copywithzone exception on object not included in current class - ios

Question

I am using a 4 UIButton that bring up the same UIPickerView but with different NSArray(4) appearing for each button. Using a 4 bool to let the UIPickerView to decide which to load, and which row's text to grab. The buttons methods just include the four bool properties, that sets the three to false and the correct one(button tapped) to true. Then UIViewAnimateWithDuration is called that brings up the UIPickerView (printed in a UIView - for both UIPickerView and UIToolbar to work together). All buttons are working just fine(no matter how many time I bring/close the UIPickerView)apart from one (even if it is pressed in first-middle-last-any order). Xcode throws the following exception:
What I did:
remove the button, create a new one
tried both storyboard/controller method of creating a button
added method to button using addtarget
linked button with method using storyboard
So what I am asking if anyone can see anything that I cannot see in my debugger's exception thrown:(sportCenter is a NSObject and it is not imported in this controller -tried that too!)

Answer 1

You must add your own copyWithZone: method in your objects...
However, I don't really understand your question / context. It looks designed in a bit complex way. Booleans array have chances to be a bad approach. It is better to have a selectedButton ( UIButton ) property in your controller, to know which one is selected, than maintain four booleans.
And finally, no matter the situation, if things are working for all objects, excepted the first one, it often means that you have an array index error somewhere.
I hope it helps.
