Question

I have a few UIpickerView’s that sends setNeedsDisplay to their parent view.
Is there any way to get the identity of the sender ?

Thanks

Answer 1

There is no way for you to get the sender of that method. There are a couple important things to note here: first, you shouldn’t be overriding setNeedsDisplay at all, you should override drawRect: which will be called if the view needs to be redrawn. Second, I would suggest you use UIPickerView‘s delegate property, set it your parent view, and then do any processing you need to do in the pickerView:didSelectRow:inComponent: delegate method.
