Deleting an object in NSArrayController

Question

I have an NSTableView which gets its data from an NSArrayController and I need to delete the currently selected row. I know NSManagedObjectContext has a deleteObject: method but, I can't think of how to delete it from the NSArrayController.

Answer 1

Use the NSArrayController's remove: action.

Answer 2

To remove programmatically

[NSArrayController removeObjectAtArrangedObjectIndex:NSInteger];

or

[NSArrayController removeObjectAtArrangedObjectIndexes:NSIndexset];

Answer 3

@NewStack's answer in Swift 3:

ArrayController.remove(atArrangedObjectIndex: Int)
