如果屏幕超出原始屏幕或屏幕下方，如何将y轴设置为0-在iPad中

Question

I am in the learning process ,I have this particular code, for whenever we click on the textfield or textview the screen moves up and when we resign the keyboard the screen gets to its original position its working fine for Both Landscape and Portrait Mode

What is the problem is. Initially it is in Portrait mode, When We click on the textfield or textview the screen is raising and the keyboard is shown, now when i rotate to landscape and resign the keyboard the screen is getting downwards and the same is happening for the vice-versa.

    - (void)animateTextField:(UITextField*)textField textView:(UITextView *)textView up:(BOOL)up{   
            int animatedDistance;  
            int moveUpValue; 

            if (textField) {  
                moveUpValue = textField.frame.origin.y+ textField.frame.size.height;  
              }  
           else {  
                moveUpValue = textView.frame.origin.y+ textView.frame.size.height;   
             }  

            NSLog(@"moveup%d",moveUpValue);

            UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];

            if (orientation == UIInterfaceOrientationPortrait ||
                 orientation == UIInterfaceOrientationPortraitUpsideDown)
              {
               if(textField){
                  animatedDistance = 216-(650-moveUpValue-5);
                }
               else{
                 animatedDistance = 216-(850-moveUpValue-5);
                }
              }
           else
             {
               if(textField){
                  animatedDistance = 162-(505-moveUpValue-5);
                }
               else{
                  animatedDistance = 162-(750-moveUpValue-5);
             }
         }
         NSLog(@"animated%d",animatedDistance);

        if(animatedDistance>0)
         {
           const int movementDistance = animatedDistance;
           const float movementDuration = 0.3f; 
           int movement = (up ? -movementDistance : movementDistance);
           NSLog(@"movement portrait%d",movement);
           [UIView beginAnimations: nil context: nil];
           [UIView setAnimationBeginsFromCurrentState: YES];
           [UIView setAnimationDuration: movementDuration];
           scrollview.frame = CGRectOffset(scrollview.frame, 0, movement);       
           [UIView commitAnimations];

         }
   }

I would like to now how can i solve this issue, or how can we change the y axis to 0.

Please Kindly do help. Thanks in Advance

当设备方向改变时，请验证animationDistance设置。
