iOS - 标签或图像的动画移动

iOS - animate movement of a label or image(iOS - 标签或图像的动画移动)

问题描述

如何为标签或图像的移动设置动画?我只想从屏幕上的一个位置缓慢过渡到另一个位置(没什么花哨的).

How can I animate the movement of a label or image? I would just like to make a slow transition from one location on the screen to another (nothing fancy).

推荐答案

您正在寻找 -beginAnimations:context: 和 -commitAnimations 方法="http://developer.apple.com/iphone/library/documentation/uikit/reference/UIView_Class/UIView/UIView.html" rel="noreferrer">UIView.

You're looking for the -beginAnimations:context: and -commitAnimations methods on UIView.

简而言之，您可以执行以下操作:

In a nutshell, you do something like:

[UIView beginAnimations:nil context:NULL]; // animate the following:
myLabel.frame = newRect; // move to new location
[UIView setAnimationDuration:0.3];
[UIView commitAnimations];
