IOS——UITextField自动适应键盘弹出

         //键盘变化监听
          [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardChange:) name:@"UIKeyboardWillChangeFrameNotification" object:nil];
  
 

      - (void)keyboardChange:(NSNotification *)aNotification
      {
         NSValue *value = [[aNotification userInfo] objectForKey:@"UIKeyboardFrameEndUserInfoKey"];
         float keyEnd_y = [value CGRectValue].origin.y;
         float animationDuration = [[aNotification userInfo][@"UIKeyboardAnimationDurationUserInfoKey"] floatValue];
         CGRect frame = [[UIScreen mainScreen]bounds];//屏幕尺寸
         CGRect viewFrame = self.view.frame;
          viewFrame.origin.y = keyEnd_y - frame.size.height;
         self.view.frame = viewFrame;
          [UIView animateWithDuration:animationDuration animations:^{
          }];
      }
