我需要在 iOS 上删除/移动应用程序效果的提示/代码, 通常我已经启动代码, 我在使用 UI按钮 列表中的 UIScroll

所以,我的问题是,假设我在屏幕中有8到10个按钮, 我想用拖动来改变它们的位置。 例如,选择 6 个按钮, 移动或设置在 1 到 2 之间, 当我把它们放在其它按钮的位置之间时, 将会改变 。

我使用 UIPanGestureRecognize 来拖曳。

问题回答

如果您已经拥有拖曳代码, 其余的很容易。 只要使用 UIView 动画即可 。

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
...
[button setFrame:newFrame];
...
[UIView commitAnimations];

基本上,只要把按钮移到他们的新位置, 开始动画- 执行动画块 。

希望这能帮上忙
