   [but setbackgroundImage:[UIImage imageNamed:@"XXX.png"] forState:UIControlStateNormal];



[self.view addSubview:but];



-(void) buttonClicked:(UIButton*)sender

 {

NSLog(@"you clicked on button %@", sender.tag);

 }

Swift

    let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)

    myButton.setTitle("Hai Touch Me", forState: .Normal)

    myButton.setTitleColor(UIColor.blueColor(), forState: .Normal)

    myButton.frame = CGRectMake(15, 50, 300, 500)

    myButton.addTarget(self, action: "pressedAction:", forControlEvents: .TouchUpInside)



    self.view.addSubview( myButton)





func pressedAction(sender: UIButton!) {

   // do your stuff here 

  NSLog("you clicked on button %@", sender.tag)

}

Swift3 and above

  let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)

    myButton.setTitle("Hi, Click me", for: .normal)

    myButton.setTitleColor(UIColor.blue, for: .normal)

    myButton.frame = CGRect(x: 15, y: 50, width: 300, height: 500)



    myButton.addTarget(self, action: #selector(pressedAction(_:)), for: .touchUpInside)

    self.view.addSubview( myButton)







func pressedAction(_ sender: UIButton) {

   // do your stuff here 

  print("you clicked on button (sender.tag)")

}

To add a button programatically to your controller's view, use the following:

-(void)viewDidLoad

{

   UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

   btn.frame = CGRectMake(0, 0, 100, 50);

   [btn setTitle:@"Hello, world!" forState:UIControlStateNormal];

   [self.view addSubview:btn];

}

To add three of these, rinse and repeat.

Here you can create dynamically a UIButton:

//For button image

UIImage *closebtnimg = [UIImage imageNamed:@"close_btn.png"];

//Custom type button

btnclose = [[UIButton buttonWithType:UIButtonTypeCustom]retain];

//Set frame of button means position

btnclose.frame = CGRectMake(103, 257, 94, 32);

//Button with 0 border so it's shape like image shape

[btnclose.layer setBorderWidth:0];

//Set title of button

[btnclose setTitle:@"CLOSE" forState:UIControlStateNormal];

[btnclose addTarget:self action:@selector(methodname:) forControlEvents:UIControlEventTouchUpInside];

//Font size of title

btnclose.titleLabel.font = [UIFont boldSystemFontOfSize:14];

//Set image of button

[btnclose setBackgroundImage:closebtnimg forState:UIControlStateNormal];

Come on, it's 2014! Why isn't code block evaluation assignment being used yet, as trends show it's the future!

UIButton* button = ({

    //initialize button with frame

    UIButton* button = [[UIButton alloc] initWithFrame:({

        CGRect frame = CGRectMake(10.0, 10.0, 200.0, 75.0);

        frame;

    })];

    //set button background color

    [button setBackgroundColor:({

        UIColor* color = [UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0];

        color;

    })];

    //set button title for state

    [button setTitle:({

        NSString* string = [NSString stringWithFormat:@"title words"];

        string;

    }) forState:({

        UIControlState state = UIControlStateNormal;

        state;

    })];

    //set selector

    [button addTarget:self action:({

        SEL select = @selector(method:);

        select;

    }) forControlEvents:({

        UIControlEvents event = UIControlEventTouchUpInside;

        event;

    })];

    //return button

    button;

});

[self.view addSubview:button];

whoa!

Or the exact results can be accomplished as such:

UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(10.0, 10.0, 200.0, 75.0)];

[button setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:0.0 alpha:1.0]];

[button setTitle:@"title words" forState:UIControlStateNormal];

[button addTarget:self action:@selector(method:) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:button];

'action:@selector(aMethod:)' write method like this :

- (void)aMethod:(UIButton*)button

   {

         NSLog(@"Button  clicked.");

  }

It works for me. Thanks. KS.

Objective-C

// Create the Button with RoundedRect type

UIButton *mybutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

// instend of "Click Me" you can write your own message/Label

[mybutton setTitle:@"Click Me" forState:UIControlStateNormal];

// create the Rectangle Frame with specified size

mybutton.frame = CGRectMake(10, 10, 300, 140); // x,y,width,height    [self.view addSubview:mybutton];// add button to your view.

Swift

let button   = UIButton(type: UIButtonType.System) as UIButton

button.frame = CGRectMake(100, 100, 100, 50)

button.backgroundColor = UIColor.greenColor()

button.setTitle("Test Button", forState: UIControlState.Normal)

self.view.addSubview(button)

try this code to create a button and repeat it for 2 more times with different coordinates and the method(myButtonClick) is called when the button is pressed

UIButton *editButton = [UIButton buttonWithType: UIButtonTypeCustom];

editButton.frame = CGRectMake(0, 0, width, height);

[editButton setBackgroundImage: editButtonImage forState: UIControlStateNormal];

[myButton addTarget:self action:@selector(myButtonClick:)    forControlEvents:UIControlEventTouchUpInside]; 

editButton.adjustsImageWhenHighlighted = YES;

editButton.titleLabel.text = @"Edit";

editButton.titleLabel.textColor = [UIColor whiteColor];

editButton.titleLabel.textAlignment = UITextAlignmentCenter;

editButton.titleLabel.font = [UIFont fontWithName: @"Helvetica" size: 14];

[self.view addSubview: editButton];



-(void) myButtonClick:(NSString *)myString{



   NSLog(@"you clicked on button %@", myString);

}

You can just put the creator instance within a loop and dynamically add names from an array if you so wish.

Check out this code:

CGRect frameimg = CGRectMake(15, 46, 55,70);

UIButton  *SelectionButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

SelectionButton.frame=frameimg;

SelectionButton.tag=i;

[SelectionButton setTitle:[SelectionArray objectAtIndex:0] forState:UIControlStateNormal];

[SelectionButton addTarget:self action:@selector(BtnSelected:)

                  forControlEvents:UIControlEventTouchUpInside];

[SelectionButton.titleLabel setFont:[UIFont boldSystemFontOfSize:12.0]];

SelectionButton.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;

SelectionButton.titleLabel.numberOfLines = 2;

SelectionButton.titleLabel.textAlignment = NSTextAlignmentCenter;

[SelectionButton setTitleColor:[UIColor grayColor] forState:(UIControlStateNormal)];

[SelectionButton setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];

[SelectionButton setShowsTouchWhenHighlighted:YES];

[self.view addSubview:SelectionButton];

I hope you find this code useful.

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

[button addTarget:self 

           action:@selector(aMethod:)

 forControlEvents:UIControlEventTouchUpInside];

[button setTitle:@"Show View" forState:UIControlStateNormal];

button.frame = CGRectMake(10.0, 100.0, 300.0, 20.0);

[self.view addSubview:button];

-(UIButton *)addButton:(NSString *)title :(CGRect)frame : (SEL)selector :(UIImage *)image :(int)tag{



UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

btn.frame = frame;

[btn addTarget:self action:selector forControlEvents:UIControlEventTouchUpInside];

[btn setTitle:title forState:UIControlStateNormal];

[btn setImage:image forState:UIControlStateNormal];

btn.backgroundColor = [UIColor clearColor];

btn.tag = tag;



return btn;



}

and you can add it to the view:

[self.view addSubview:[self addButton:nil :self.view.frame :@selector(btnAction:) :[UIImage imageNamed:@"img.png"] :1]];

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

[button addTarget:self 

       action:@selector(aMethod:)

 forControlEvents:UIControlEventTouchDown];

[button setTitle:@"Show View" forState:UIControlStateNormal];

button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);

[view addSubview:button];

This is an example as well to create three buttons. Just move their location.

UIImage *buttonOff = [UIImage imageNamed:@"crysBallNorm.png"];

UIImage *buttonOn = [UIImage imageNamed:@"crysBallHigh.png"];



UIButton *predictButton = [UIButton alloc];

predictButton = [UIButton buttonWithType:UIButtonTypeCustom];

predictButton.frame = CGRectMake(180.0, 510.0, 120.0, 30.0);

[predictButton setBackgroundImage:buttonOff forState:UIControlStateNormal];

[predictButton setBackgroundImage:buttonOn forState:UIControlStateHighlighted];

[predictButton setTitle:@"Predict" forState:UIControlStateNormal];

[predictButton setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];

[predictButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:predictButton];

You can create button by this code.

 UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

 [btn addTarget:self action:@selector(btnAction) forControlEvents:UIControlEventTouchDragInside];

 [btn setTitle:@"click button" forState:UIControlStateNormal];

  btn.frame = CGRectMake(50, 100, 80, 40);

  [self.view addSubview:btn];

Here is the button action method

 -(void)btnAction

 {

   NSLog(@"button clicked");

 }

For Swift 2.0:

let btnObject : UIButton  = UIButton() 

btnObject.frame = CGRect(x: 8, y: 89, width: 70, height: 22)



btnObject.titleLabel?.font = UIFont(name: "Helvetica Neue", size: 13)

btnObject.titleLabel?.textColor = UIColor.whiteColor()

btnObject.backgroundColor = UIColor(red: 189/255, green: 176/255, blue: 0/255, alpha: 1)

btnObject.titleLabel?.textAlignment = NSTextAlignment.Center

btnObject.addTarget(self, action: "btnbtnObjectClick:", forControlEvents: UIControlEvents.TouchUpInside)

subView.addSubview(btnObject)

For creating UIButton programmatically we can create in both objective c and swift

SWIFT 3

let buttonSwift   = UIButton(type: UIButtonType.system) as UIButton

                      //OR 

let buttonSwift   = UIButton(type: UIButtonType.Custom) as UIButton

//Set Frame for Button

buttonSwift.frame = CGRect(x: 100, y: 100, width: 200, height: 100)

//Set title for button

buttonSwift.setTitle("ClickMe", for: .normal)

//If you want to set color for button title

buttonSwift.setTitleColor(UIColor.white, for: .normal)

//If you want to set Background color for button

buttonSwift.backgroundColor = UIColor.black

//If you want to set tag for button

buttonSwift.tag = 0

//If you want to add or set image for button

let image = UIImage(named: "YourImageName") as UIImage?

buttonSwift.setImage(image, for: .normal)

//If you want to add or set Background image for button

buttonSwift.setBackgroundImage(image, for: .normal)

//Add action for button

buttonSwift.addTarget(self, action: #selector(actionPressMe), for:.touchUpInside)

//Add button as SubView to Super View

self.view.addSubview(buttonSwift)

UIButton Action Method

func actionPressMe(sender: UIButton!) 

{

    NSLog("Clicked button tag is %@", sender.tag)

               OR

    print("Clicked button tag is (sender.tag)")



    //Then do whatever you want to do here



    ........  

}

OBJECTIVE C

UIButton *buttonObjectiveC = [UIButton buttonWithType:UIButtonTypeCustom];

           OR

UIButton *buttonObjectiveC = [UIButton buttonWithType:UIButtonTypeSystem];

buttonObjectiveC.frame = CGRectMake(200, 100, 200, 100);

//Set title for button

[buttonObjectiveC setTitle:@"ClickMe" forState:UIControlStateNormal];

//If you want to set color for button title

[buttonObjectiveC setTitleColor:[UIColor  whiteColor] forState: UIControlStateNormal];

//If you want to set Background color for button

[buttonObjectiveC setBackgroundColor:[UIColor blackColor]];

//If you want to set tag for button

buttonSwift.tag = 0;

//If you want to add or set image for button

UIImage *image = [UIImage imageNamed:@"YourImageName"];

[buttonObjectiveC setImage:image forState:UIControlStateNormal];

//If you want to add or set Background image for button

[buttonObjectiveC setBackgroundImage:image forState:UIControlStateNormal];

//Add action for button

[buttonObjectiveC addTarget:self action:@selector(actionPressMe:)forControlEvents:UIControlEventTouchUpInside];

//Add button as SubView to Super View

[self.view addSubview:buttonObjectiveC];

UIButton Action Method

- (void)actionPressMe:(UIButton *)sender 

{

    NSLog(@"Clicked button tag is %@",sender.tag);

    //Then do whatever you want to do here

    ..........

}

Output Screenshot is

-(void)addStuffToView

{

    UIButton *aButton = [[UIButton alloc] initWithFrame:CGRectMake(20, 20, 20, 20)]; //(x, y, width, height of button on screen

    [aButton setTitle:@"Button" forState:UIControlStateNormal];//puts the text on the button

    aButton.titleLabel.font = somefont;//sets the font if one is already stated

    aButton.titleLabel.font = [UIFont fontWithName:@"Arial-MT" size:12];//sets the font type and size

    [aButton addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];//see back method below

    [aButton setBackgroundImage:[UIImage imageNamed:@"someImage.png"] forState:UIControlStateNormal];//sets the image of the button

    [self.view addSubview:back];

}



-(void)back

{

    UIAlertView *alert = [[UIAlertView alloc]initWithTitle.....]

}



-(void)viewDidLoad

{

    [super viewDidLoad];

    [self addStuffToView];//adds all items built in this method to the view

}

For Swift 2.2 (with the with the new "selector" declaration).

let btn = UIButton(type: UIButtonType.System) as UIButton

btn.frame = CGRectMake(0, 0, 100, 20) // set any frame you want

btn.setTitle("MyAction", forState: UIControlState.Normal)

btn.addTarget(self, action: #selector(MyClass.myAction(_:)), forControlEvents: UIControlEvents.TouchUpInside)

self.view.addSubview(btn)





func myAction(sender:UIButton!){

  // Some action 

}

You can implement it in your ViewDidLoad Method:

continuebtn = [[UIButton alloc]initWithFrame:CGRectMake(10, 100, view1.frame.size.width-20, 40)];

    [continuebtn setBackgroundColor:[UIColor grayColor]];

    [continuebtn setTitle:@"Continue" forState:UIControlStateNormal];

    continuebtn.layer.cornerRadius = 10;

    continuebtn.layer.borderWidth =1.0;

    continuebtn.layer.borderColor = [UIColor blackColor].CGColor;

    [continuebtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    [continuebtn addTarget:self action:@selector(continuetonext) forControlEvents:UIControlEventTouchUpInside];

    [view1 addSubview:continuebtn];

Where continuetonext is:

-(void)continuetonext

{

    GeneratePasswordVC *u = [[GeneratePasswordVC alloc]init];

    [self.navigationController pushViewController:u animated:YES];

}

As of Swift 3, several changes have been made to the syntax.

Here is how you would go about creating a basic button as of Swift 3:

    let button = UIButton(type: UIButtonType.system) as UIButton

    button.frame = CGRect(x: 100, y: 100, width: 100, height: 50)

    button.backgroundColor = UIColor.green

    button.setTitle("Example Button", for: UIControlState.normal)

    self.view.addSubview(button)

Here are the changes that have been made since previous versions of Swift:

let button = UIButton(type: UIButtonType.System) as UIButton



// system no longer capitalised



button.frame = CGRectMake(100, 100, 100, 50)



// CGRectMake has been removed as of Swift 3



button.backgroundColor = UIColor.greenColor()



// greenColor replaced with green



button.setTitle("Example Button", forState: UIControlState.Normal)



// normal is no longer capitalised



self.view.addSubview(button)

Try it....

UIButton *finalPriceBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];

finalPriceBtn.frame=CGRectMake(260, 25, 45, 15);

[finalPriceBtn addTarget:self action:@selector(goBtnClk:) forControlEvents:UIControlEventTouchUpInside];

finalPriceBtn.titleLabel.font=[UIFont systemFontOfSize:12];

[finalPriceBtn setTitle:[NSString stringWithFormat:@"$%.2f",tempVal] forState:UIControlStateNormal];

finalPriceBtn.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f  alpha:1];

finalPriceBtn.titleLabel.textAlignment=UITextAlignmentLeft;

[imageView addSubview:finalPriceBtn];

Hope i helped.

UIButton *custombutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

[custombutton addTarget:self

                 action:@selector(aMethod:)

       forControlEvents:UIControlEventTouchUpInside];

[custombutton setTitle:@"Click" forState:UIControlStateNormal];

custombutton.frame = CGRectMake(80.0, 110.0, 160.0, 40.0);

custombutton.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f  alpha:1];

 [custombutton setImage:[UIImage imageNamed:@"hh.png"] forState:UIControlStateNormal];

 [view addSubview:custombutton];

For Swift 3 (even shorter code)

let button = UIButton(type: UIButtonType.custom)

button.frame = CGRect(x: 0, y: 0, width: 200.0, height: 40.0)

button.addTarget(nil, action: #selector(tapButton(_:)), for: UIControlEvents.touchUpInside)

button.tintColor = UIColor.white

button.backgroundColor = UIColor.red

button.setBackgroundImage(UIImage(named: "ImageName"), for: UIControlState.normal)

button.setTitle("MyTitle", for: UIControlState.normal)

button.isEnabled = true



func tapButton(sender: UIButton) {



}

Swift3 version should be

let myButton:UIButton = {

            let myButton = UIButton() // if you want to set the type use like UIButton(type: .RoundedRect) or UIButton(type: .Custom)

            myButton.setTitle("Hai Touch Me", for: .normal)

            myButton.setTitleColor(UIColor.blue, for: .normal)

            myButton.frame = CGRect(x: 20, y: 20, width: 100, height: 40)



            myButton.addTarget(self, action: #selector(ViewController.pressedAction(_:)), for: .touchUpInside)

            self.view.addSubview(myButton)



            return myButton



        }()

UIButton *buttonName = [UIButton

buttonWithType:UIButtonTypeRoundedRect];

[buttonName addTarget:self 

    action:@selector(aMethod:)forControlEvents:UIControlEventTouchDown];

[buttonName setTitle:@"Show View" forState:UIControlStateNormal];

.frame = CGRectMake(80.0, 210.0, 160.0, 40.0); [view

addSubview:buttonName];

In Swift 4.1 and Xcode 10

Basically we have two types of buttons.

1) System type button

2) Custom type button (In custom type button we can set background image for button)

And these two types of buttons has few control states https://developer.apple.com/documentation/uikit/uicontrol/state

Important states are

1) Normal state

2) Selected state

3) Highlighted state

4) Disabled state etc...

//For system type button

let button = UIButton(type: .system)

button.frame = CGRect(x: 100, y: 250, width: 100, height: 50)

//  button.backgroundColor = .blue

button.setTitle("Button", for: .normal)

button.setTitleColor(.white, for: .normal)

button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 13.0)

button.titleLabel?.textAlignment = .center//Text alighment center

button.titleLabel?.numberOfLines = 0//To display multiple lines in UIButton

button.titleLabel?.lineBreakMode = .byWordWrapping//By word wrapping

button.tag = 1//To assign tag value

button.btnProperties()//Call UIButton properties from extension function

button.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)

self.view.addSubview(button)



//For custom type button (add image to your button)

let button2 = UIButton(type: .custom)

button2.frame = CGRect(x: 100, y: 400, width: 100, height: 50)

//        button2.backgroundColor = .blue

button2.setImage(UIImage.init(named: "img.png"), for: .normal)

button2.tag = 2

button2.btnProperties()//Call UIButton properties from extension function

button2.addTarget(self, action:#selector(self.buttonClicked), for: .touchUpInside)

self.view.addSubview(button2)



@objc func buttonClicked(sender:UIButton) {

    print("Button (sender.tag) clicked")

}



//You can add UIButton properties like this also

extension UIButton {

    func btnProperties() {

        layer.cornerRadius = 10//Set button corner radious

        clipsToBounds = true

        backgroundColor = .blue//Set background colour

        //titleLabel?.textAlignment = .center//add properties like this

    }

}

UIButton *btnname = [UIButton buttonWithType:UIButtonTypeRoundedRect];



[btnname setTitle:@"Click Me" forState:UIControlStateNormal];



btnname.frame = CGRectMake(10, 10, 100, 140);



[self.view addSubview:btnname];

UIButton * tmpBtn = [UIButton buttonWithType:UIButtonTypeCustom];

[tmpBtn addTarget:self action:@selector(clearCart:) forControlEvents:UIControlEventTouchUpInside];

tmpBtn.tag = k;

tmpBtn.frame = CGRectMake(45, 0, 15, 15);

[tmpBtn setBackgroundImage:[UIImage imageNamed:@"CloseButton.png"] forState:UIControlStateNormal];

[self.view addSubview:tmpBtn];
