iphone - IOS7 がカメラでクラッシュする

Question

iOS7 で以下を実行すると、アプリケーションがクラッシュします。そのiOS6で完全に正常に動作していました

UIImagePickerController *ImagePicker;

@try {
   ImagePicker = [[[UIImagePickerController alloc]init]autorelease];
   ImagePicker.sourceType= UIImagePickerControllerSourceTypeCamera;
   ImagePicker.showsCameraControls = NO;
   ImagePicker.toolbarHidden = YES;
   ImagePicker.navigationBarHidden= YES;
   //  ImagePicker.wantsFullScreenLayout = YES;

   ImagePicker.cameraViewTransform = CGAffineTransformScale(ImagePicker.cameraViewTransform, CAMERA_TRANSFORM, CAMERA_TRANSFORM);  
}
@catch (NSException *exception) {
    [ImagePicker release];
    ImagePicker = nil;
}
@finally {

    if(ImagePicker)
    {
        [cameralayer addSubview:[ImagePicker view]];
        [cameralayer release];
    }

}
