Setting layer properties for IBOutletCollection

I'm trying to set the layer properties of multiple buttons connected to an IBOutletCollection but the IBOutletCollection doesn't let me access UIButton.layer the same as it does for a regular IBOutlet.

Interface file:

@property (strong, nonatomic) IBOutletCollection(UIButton) NSArray *customButton;
@property (weak, nonatomic) IBOutlet UIButton *myButton;

Implementation file

myButton.layer.cornerRadius = 9; // this works for individual buttons
customButton.layer.cornerRadius = 9; //This doesn't work for the collection of buttons

Am I missing something? Do I need to do something else to adjust the layer properties of a collection? I've imported QuartzCore into my implementation file.

I'm only trying to add 4 buttons to the collection so its not the end of the world if I have to set each on independently but it would be nice to be able to set them up together.

Solution

  • customButton is an NSArray.It doesnt have the layer as property.

    Use this

    for (UIButton *button in customButton) {
        button.layer.cornerRadius = 9;
    }
