My App crashes when launched on my Iphone
- by Miky Mike
hi guys,
I have a problem here : my app crashed on my Iphone (JB) though Xcode doesn't complain about anything. The app works fine on the simulator though.
However, there is this in the device logs :

Any idea what the problem can be ?
I've already spent my whole day on that, but... I'm stuck.
Thanks in advance...
