Don't Declare the picker in .h file. Simple Declare and Use in Button Action and Release after work will finish.

-(IBAction)cameraAction:(id)sender
{

   NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
   [defaults setValue:@"rear" forKey:@"rearcamera"];
   [defaults synchronize];
   NSLog(@"hai App %@",[defaults valueForKey:@"closeApp"]);

   dispatch_async(dispatch_get_main_queue(), ^{
       [cameraBut setSelected:NO];
      UIImagePickerController *picker = [[UIImagePickerController alloc] init];
      picker.sourceType = UIImagePickerControllerSourceTypeCamera;
      picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
      picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
      picker.showsCameraControls = NO;
      picker.navigationBarHidden = YES;
      picker.toolbarHidden = YES;
      picker.wantsFullScreenLayout = YES;

      [self presentViewController:picker animated:YES completion:nil];

   });


}

As per your explanation, I guess you require to open camera shutter only and your camera is working perfectly.

So I would suggest you to add one animation, which will simulate camera shutter opening.

Here is the code for that, this one is Core Animation for CALayer:

CATransition *shutterAnimation = [CATransition animation];
     [shutterAnimation setDelegate:self];
     [shutterAnimation setDuration:0.6];

     shutterAnimation.timingFunction = UIViewAnimationCurveEaseInOut;
     [shutterAnimation setType:@"cameraIris"];
     [shutterAnimation setValue:@"cameraIris" forKey:@"cameraIris"];
     CALayer *cameraShutter = [[CALayer alloc]init];
     [cameraShutter setBounds:CGRectMake(0.0, 0.0, 320.0, 425.0)];
     [self.layer addSublayer:cameraShutter];
     [self.layer addAnimation:shutterAnimation forKey:@"cameraIris"];

This is not the exact solution, but this is one of the way around.

Hope this will help you to achieve your requirement.
