uiimagepicker crash when calling takepicture method - ios

Question

I am using custom camera with the help of UIImagePickerController. I am subclassing the UIImagePickerController class and using without present/dismiss. We are just opening the customise camera view and taking picture. After sometime by clicking camera takepicture method gets called and app is getting crash. No delegate method called during this. My code is this:
-(void)viewDidLoad
{
if([UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear] && self.camType==2)
{
self.sourceType=UIImagePickerControllerSourceTypeCamera;
self.cameraDevice=UIImagePickerControllerCameraDeviceRear;
self.showsCameraControls = NO;
self.wantsFullScreenLayout=NO;
self.navigationBar.hidden=NO;
self.cameraOverlayView = mainView;
}
}
else
{
self.navigationBar.hidden=YES;
self.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
[notAllowBtn setHidden:TRUE];
[cmView setHidden:TRUE];
}
self.delegate=self;
[self.view addSubview:cmView];
}
-(void)cameraTakePic {
if([UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear]) {
[self takePicture];
}
}
- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info{
if (![info objectForKey:#"UIImagePickerControllerOriginalImage"]) {
NSArray *arr=[[appDel navController] viewControllers];
id obj=[arr lastObject];
UIViewController *objContr=((UIViewController *)obj);
objContr.navigationController.navigationBar.userInteractionEnabled = YES;
[clickBtn setEnabled:YES];
return;
}
UIImage* image = nil;
UIImage *imageTemp = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
}

From the Apple UIImagePickerController class reference:
The UIImagePickerController class supports portrait mode only. This
class is intended to be used as-is and does not support subclassing.
The view hierarchy for this class is private and must not be modified,
with one exception. You can assign a custom view to the
cameraOverlayView property and use that view to present additional
information or manage the interactions between the camera interface
and your code.
You shouldn't subclass the UIImagePickerController class, instead you should use AVFoundation and make your custom capture methods.
