I see there are similar problems posted here, but none of the solutions work for me. Here goes:
I have a UIButton instance inside a UIView frame, which is positioned within another UIView frame, which is positioned in the main window UIView. To wit:
UIWindow
--> UIView (searchView)
--> UISearchBar (findField)
--> UIView (prevButtonView)
--> UIButton (prevButton)
--> UIView (nextButtonView)
--> UIButton (nextButton)
So far, so good: everything is laid out as I want it. However, the buttons aren't accepting user input of any kind. I am using the UIButton method addTarget:action:forControlEvents: and to give you an idea of what I'm doing, here's my code for nextButton:
nextButton = [UIButton buttonWithType:UIButtonTypeCustom];
[nextButton setImage:[UIImage imageNamed:@"find_next_on.png"] forState:UIControlStateNormal];
[nextButton setImage:[UIImage imageNamed:@"find_next_off.png"] forState:UIControlStateDisabled];
[nextButton setImage:[UIImage imageNamed:@"find_next_off.png"] forState:UIControlStateHighlighted];
[nextButton addTarget:self action:@selector(nextResult:) forControlEvents:UIControlEventTouchUpInside];
The method nextResult: never gets called, the state of the button doesn't change on touching, and there's not a damned thing I've been able to do to get it working. I assume that there's an issue with all these layers of views: maybe something is sitting on top of my button, but I'm not sure what it could be.
In the interest of information overload, I found a bit of code that would print out all my view info. This is what I get for my entire view hierarchy:
UIWindow
{{0, 0}, {320, 480}}
UILayoutContainerView
{{0, 0}, {320, 480}}

The relevant part is noted above the UINavigationBar section.
Anyone have any suggestions? I'm all out.
Thanks for reading.
