如何在使用UIPanGestureRecognizer時將超級視圖與視圖集中在一起？

Question

我創建了一個示例應用程序，當我們點擊一​​個按鈕時出現另一個視圖（ResizingViewController）視圖。 當我拖動ResizingViewController時，它正在正確移動，但我可以看到它背後的另一個視圖。我認爲它是超級視圖（如圖中所示，但不能同時移動）。

請幫我解決這個問題？（如果我拖到視圖，則兩者都應該移動到相同的位置）

我的代碼如下

- (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]; 

}

OK我解決了這個問題。 （標記爲答案，以便如果任何人有同樣的問題可以使用此）

-(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]; 

}
