Error trying to run app on iOS device. It runs on emulator

Question

I'm getting a weird issue trying to load my app using ZXing on my iPhone. It runs on the simulator, but when I tried to run it on my iPhone it says:

error: failed to launch '/Users/....../MyApp.app/MyApp' -- No such file or directory

And If a look into that path the file already exist!

Why could this be happening?

Am woking on iOS 5.1 (targeting 4.0) with the last version of ZXing.

重新启动XCode，也许这是解决方案。
