How to center superview along with view when using UIPanGestureRecognizer? - ios

Question

I Created a sample application, when we click on a button another view(ResizingViewController) view shows up.
when i drag ResizingViewController it is moving correctly but i can see another view behind it.I think it is super view (as show in in this image, but not able to make both move at same time).
please help me to fix it?(if i drag view then both should move to same position)
my code is as below
- (IBAction)click_Action:(id)sender {
if (!resizingViewController) {
return;
}
//Creating Right Button, asigning a method to it.
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:#"Close"
style:UIBarButtonItemStylePlain target:self action:#selector(done)];
[resizingViewController.navigationItem setRightBarButtonItem:rightButton];
theNavigationController = [[UINavigationController alloc]
initWithRootViewController:resizingViewController];
[theNavigationController.navigationBar setTintColor:[UIColor blueColor]];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
theNavigationController.modalPresentationStyle
=UIModalPresentationFormSheet;
}
[self presentViewController:theNavigationController animated:YES completion:nil];
CGRect r = CGRectMake(100, 100, 300, 400);
r = [self.view convertRect:r toView:self.view];
theNavigationController.view.superview.frame = r;
//Adding gesture reconizer to resizingviewcontroller
UIPanGestureRecognizer *panGestureRecognizer = [[UIPanGestureRecognizer alloc]
initWithTarget:self action:#selector(handlePanFrom:)];
[theNavigationController.view addGestureRecognizer:panGestureRecognizer];
}
-(void)handlePanFrom:(UIPanGestureRecognizer *) recognizer
{
CGPoint translation = [recognizer translationInView:recognizer.view];
//Changing Center of the the view as soon as user selects the view and drags
recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x,
recognizer.view.center.y + translation.y);
CGPoint r = CGPointMake(recognizer.view.center.x+100,
recognizer.view.center.y+100);
r = [self.view convertPoint:r toView:self.view];
recognizer.view.superview.center = r;
//Should not forget to give below code, else view goes out of bounds.
[recognizer setTranslation:CGPointZero inView:self.view];
}

Answer 1

OK i fixed this.(marking this as answer so that if any one have same problem can use this)
-(void)handlePanFrom:(UIPanGestureRecognizer *) recognizer
{
CGPoint translation = [recognizer translationInView:recognizer.view.superview];
recognizer.view.superview.center =
CGPointMake(recognizer.view.superview.center.x+translation.x,
recognizer.view.superview.center.y+translation.y);
[recognizer setTranslation:CGPointZero inView:self.view];
}
