Black screen stays in iphone when application is launched from Xcode 4.2
===

I am directly running the application in my iPhone from Xcode. When the application is launched, a black screen appears and it hangs there. The same project runs smoothly in another MAC using the same device. How to make it work ?

**XCode 4.2 Build 4c199**

**Mac OS X 10.6.8**

The application is working well in iOS Simulator.

**Output from the console :**
