NSTableView bound to NSArrayController but not showing data until another object is added












0















Binding is working but it seems ridiculous that I need to add an object in order for the NSTableView to show the data. Calling the NSArrayController.rearrangeObjects and the NSTableView.reloadData didn't change anything. Should this be somewhere else beside viewDidLoad? Is there a property I haven't set? Thanks!



override func viewDidLoad() {
super.viewDidLoad()
// Do view setup here.

//categories is an array of strings
categories = db.categories

categoryArrayController.addObject("")
categoryArrayController.removeObject("")
}

  • In the attributes inspector of the Array Controller, categories is set as the entity name (it's also a property of the view controller). The array controller is also bound to the view controller with the model key path set to categories. The categories array has about 25 entries but they are only shown in the table view after an object is added or removed. The array controller seems to need a nudge to reload the objects into the table but this is an awkward solution. I hope there is a better way.

  • Should the array controller fetch the categories (array of NSMangedObject) or use the categories property of the view controller? Is categories marked with @objc dynamic?
