iPad App for iPad 4.2.1 no support

My actual iPad Application causes an Exception. I try to run it on a real device. With the simulator for iPad 4.2. or 4.3. everything runs perfect. For my iPhone it also runs (for building it for iPhone device of course).

My deployment target is 3.2.2 and i get the following exception during starting the application on the iPad:

> warning: Unable to read symbols for

I have no ide开发者_如何学编程a which setting in Xcode is set wrong. ...and i am using xCode 4.0.2.!

Nothing wrong in Xcode settings, you tried to use KVC with a class that is not KVC compliant.
