我用写了个动画来播放图片，但我发现当我点击按钮切换下一张图片时

flag/**

• 执行动画
  *
• @param position 目标位置

• @param fromPosition 初始位置
  */

• (void)setAnimateWithPosition:(CGFloat)position fromPosition:(CGFloat)fromPosition
  {

  
  CGRect frame = self.totalView.frame;
  frame.origin.x = fromPosition;
  self.totalView.frame = frame;
  frame.origin.x = position;
  self.totalView.hidden = NO;
  [UIView animateWithDuration:0.5 animations:^{
      self.totalView.frame = frame;
      
  } completion:^(BOOL finished) {
      
  }];

  }
