推荐答案

编辑完整视图时会向上移动并在完成后编辑将向下移动...

While editing complete View will move up and after done editing will move down...

- (void)textViewDidBeginEditing:(UITextView *)textView
{
   [self animateTextView: YES];
 }

- (void)textViewDidEndEditing:(UITextView *)textView
 {
   [self animateTextView:NO];
  }

- (void) animateTextView:(BOOL) up
    {
        const int movementDistance =heightKeyboard; // tweak as needed
        const float movementDuration = 0.3f; // tweak as needed
        int movement= movement = (up ? -movementDistance : movementDistance);
        NSLog(@"%d",movement);

        [UIView beginAnimations: @"anim" context: nil];
        [UIView setAnimationBeginsFromCurrentState: YES];
        [UIView setAnimationDuration: movementDuration];
        self.view.frame = CGRectOffset(self.inputView.frame, 0, movement);
        [UIView commitAnimations];
    }
