Question

I have a UIView – which I am using as a makeshift toolbar. It contains several UIButtons. (Six, I think) in a horizontal row.

The fifth button over will only respond to [TouchUpInside] events when I click the left half of it – whereas all the other buttons work correctly.

I have gone crazy making sure there weren’t any other views overlapping it, etc – and everything seems okay.

Any idea of how to investigate further? Is there any way to see an “event inspector” to see where the touch messages may be going?

Answer 1

The problem was as follows:

The “sixth” button was a “Info Light” type button. For some odd reason – even though the bounds of this button were clearly outside of the bounds of the offending “fifth” button – the “info light” button seems to acquire touches a bit outside it’s bounding box.

When I either:

1. Moved the “Info Light” button further away from the “fifth” button

-or-

2. Changed the “Info Light” button to a regular (Round Rect) button

…the problem went away!
