How to get the frame of a view inside another view?

Question

Answer 1

There are four UIView methods which can help you, converting CGPoints and CGRects from one UIView coordinate reference to another:

– convertPoint:toView:
– convertPoint:fromView:
– convertRect:toView:
– convertRect:fromView:

so you can try

CGRect f = [imageView convertRect:button.frame toView:self.view];

or

CGRect f = [self.view convertRect:button.frame fromView:imageView];
