UIButton inside UIView doesn't respond to touch events

Looking at the test project, I believe your problem in the way you create TestView, you do not specify the frame for it, so basically the parent view is 0 size, and the subviews you see from XIB extending out of the parent view and thus do not get anything in responder chain.

You should either specify the frame when creating TestView, or adjust the frame after loading XIB file.

I have had this problem as well. The cause for me was that the UIButton superview frame was of height 0, so I believe that even though a touch was happening, it was not being passed down to the button.

After making sure that the button's superview took a larger rectangle as a frame the button actions worked.

The root cause for this problem on my side was a faulty auto layout implementation (I forgot to set the height constraint for the button's superview).

I've found the solution. I was initializing my custom view as:

MyView *view = [[MyView alloc] init];

I've initialized it instead with a frame of my view's size, and it started responding to events:

CGRect rect = CGRectMake(0,0,width,height);
MyView *view = [[MyView alloc] initWithFrame:rect];
