问题
I ran into a problem lately. The UITapgesture working on simulator perfect and even while debugging directly on the device (iPhone 4, iOS 5.0.1) but when I package the app (Dep_Target iOS4.0m Base_SDK iOS5.1(latest)) for adhoc distribution and send it to client the gestures doesn't work. I then installed the build via test flight on the same device which I am using for debugging, the gesture doesn't work on it. I rechecked everything, I am using same build for distribution. Any help will be much appreciated. Thanks
EDIT:
after doing a bit debugging it turns out that UITapgesture is not the culprit. The gesture method is getting fired but I've used a UIMenuController inside the gesture. The menu controller gets instantiated and all but not gets displayed on view. Besides the method:
- (BOOL) canPerformAction:(SEL)selector withSender:(id) sender
is not getting fired too. Do remember this all is happening in the build which is distributed via test flight, otherwise everything runs perfect.
回答1:
I was getting this issue in one of my application and writing [self becomeFirstResponder]
at the very first line in the function (i.e. before the line [[UIMenuController alloc] init]) solved my problem.
