iphone - 多对象拖动

Question

使用以下代码拖动多个对象时，当我触摸对象时，对象正在晃动，

   -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
    {
UITouch *touch = [[event allTouches] anyObject];
    if ([touch view] == img1)
    {
        CGPoint location = [touch locationInView:touch.view];
        img1.center = location;
        return;
    }
    if (touch.view == img2)
    {
        CGPoint location = [touch locationInView:touch.view];
        img2.center = location;
        return;
    }
    }
    -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchesBegan:touches withEvent:event];
     }

我的代码有什么问题，还有其他方法可以拖动吗？如果视图包含更多对象？请帮我解决这个问题

我认为，如果您正在谈论一次要拖动的更多对象，那么您应该从 touch begin 方法中删除返回
