Time limit for an IBAction?

It may sound as a dumb question. In fact, I am still thinking if that might be the cause but working with XCode and having set iOS 4.3 as my Deployment Target and iPad a开发者_如何学Cs my Device I am getting an unexpected error.

While running my app through the Simulator I can get it working. But when I run it through my iPad a single IBAction, fired when user taps an UIButton, that takes almost 4 minutes is not completing. In fact it's getting stopped at the same point, in a for loop.

I searched for memory leaks using XCode and it didn't find any, therefore I'm asking if there's a time limit for IBActions. I read there are 10 minutes limit for methods in background but I didn't find anything related to IBActions in foreground yet.

I think the user gets tired of waiting for a response long before the system. Normally, a button press or similar should finish after one second at most (well, maybe 1.5s), or the user thinks that the system is "slow".

I would make sure that you have your button outlets properly hooked up. It is possible that it just isn't throwing the exception so you get a slow system. Put NSLog displays in your IBAction method and make sure it is executing it properly. You should be able to track it back to figure out what is going on.
