Question

I move some UIButtons off screen and I can still enumerate them when I go through the subviews. I want to “release” them to make the script run faster, but how do I do that on iOS with ARC?

Answer 1

Thank you for all your respond but the correct answer to my question (in releasing instance objects. I should have put that in the question…sorry guys) are as follow:

for (int x =0; x<[toBeDeletedArray count]; x++) {
     UIButton* __weak butt = (UIButton*)[toBeDeletedArray objectAtIndex:x];
     [butt removeFromSuperview];
     butt = nil;
     }

The key point is to declare it “__weak”, then it can be set to nil.

Thanks for all your inspiration!
