在拖动UIButton时移动拖动手柄

我有一个视图具有响应拖动事件的UIButton。这一切都正常工作，问题是该按钮只有70X70，拖动时用于手指的按钮图像大部分被手指遮住（该过程是用户拖动图像（UIButton）到视图上的目标区域）。有没有办法来抵消拖动手柄，所以它不是UIButton的中心点？理想情况下，我希望它是UIbutton图像的右上角，因为左下角是我最关心用户看到的区域。在拖动UIButton时移动拖动手柄

编辑：这是我用来处理触摸（拖拽）事件的代码：

- (IBAction) imageTouch:(id) sender withEvent:(UIEvent *) event 
{ 
    UIButton *thisButton = (UIButton *)sender; 

    CGPoint centerPoint = [[[event allTouches] anyObject] locationInView:self.view]; 
    UIControl *control = sender; 
    control.center = centerPoint; 

    UIColor *selColor = [WebImageOperations getColorFromImage:self.targetImageView.image atX:point.x andY:point.y]; 

    NSInteger thisScore = [Scoring scoreFromUIColor:selColor withArrow:thisButton.tag]; 

    switch (thisButton.tag) { 
     case 10: 
      arrow10Score = thisScore; 
      self.score10Label.text = [NSString stringWithFormat:@"%d", arrow10Score]; 
      break; 
     case 12: 
      arrow12Score = thisScore; 
      self.score12Label.text = [NSString stringWithFormat:@"%d", arrow12Score]; 
      break; 
     case 14: 
      arrow14Score = thisScore; 
      self.score14Label.text = [NSString stringWithFormat:@"%d", arrow14Score]; 
      break; 

     default: 
      break; 
    } 

    NSInteger totalScore = arrow10Score + arrow12Score + arrow14Score; 
    self.totalScoreLabel.text = [NSString stringWithFormat:@"%d", totalScore]; 
}
