In my example I am using iCarousel in which I am trying to expand image on clicking on it? What I have done,after image expands I am adding backButton on right
backButton
I also had the same problem but I have resolved with below code.
view.userInteractionEnabled = YES;
view = your carousel view item
OR
[yourButton.superview setUserInteractionEnabled:YES];
hope it helps to others.
cheers!!!!
