推荐答案

可以使用 UIView的动画很容易达到这一目的。
用法取决于你如何把你的标签在屏幕上。

you can use UIView animation very easily for this purpose. The usage depends on how your are placing your label on screen.

1，如果你把它放在你的观点用故事板和您正在使用自动布局，您需要将约束在您的视图控制器的头文件链接到一个出口的动画恒定值。

1- if you've placed it on your view using storyboard and you are using auto layout, you need to link your constraint to an outlet in your view controller's header file for animating the constant value.

        [UIView animateWithDuration:0.2f animations:^{self.labelConstrint.constant=anyNumberoulike; 
        [self.view layoutIfNeeded]; 
        }];

2 - 如果你使用故事板没有自动排版（你应该），或者如果你正在创建你code标记，动画只是动画x或标签的框架矩形的Ÿ一部分。

2- if you are using storyboard without the auto layout (which you should) or if you are creating you label in code, the animation is simply animating the x or y part of the label's frame rect.

 [UIView animateWithDuration:0.2f animations:^{
self.label.frame=CGRectMake(finaLocationsX,self.label.frame.origin.y,self.label.frame.size.width, self.label.frame.size.height);
            }];
