Question

Error when deploying app to the device in iphone

Answer 1

+2 A:

There's no method in either Cocoa or Cocoa Touch called dateInformation. So it sounds like you've got one of the following:

A category on NSDate that provides dateInformation, but isn't being compiled into your device builds (Possible, but unlikely)
A method on some other object that's not an NSDate but does have a dateInformation method. However, if your other object gets deallocated, it's possible that the memory formerly occupied by the object could be recycled for use with an NSDate. (much more likely) You can debug this by running with NSZombieEnabled set to YES in your program environment (or use the Zombies instrument).

But there is no place in my code that I called a method with that name. Why this doesn't happen in the simulator? Shouldn't be the same?

@Rafael no, the differences between the simulator and the device are well documented elsewhere. From the Run menu in Xcode, choose "Stop on Objective-C Exceptions" and re-run. When it hits that error, it'll stop and you'll be able to see where the error is originating.

@dave thank you very much for you help. It happened to be the case 1. I was using a library that implemented dateInformation... It wasn't building properly in the device because I forgot to add a flag in the build that was required by the library... The only thing I don't understand is why this didn't cause a problem for the simulator... I need to learn more about it...
