iPhone OS是否支持隐式动画？ [英] Does iPhone OS support implicit animation?

问题描述

Mac OS X中的示例：

Example from Mac OS X:

[[aView animator] setFrame:NSMakeRect(100.0,100.0,300.0,300.0)]; 

我在UIKit中尝试过类似的方法，但是UIView似乎没有动画器方法。因此，没有隐式动画吗？

I have tried something similar in UIKit, but it seems the animator method is not there for UIView. So there's no "implicit" animation?

推荐答案

iPhone支持隐式动画，尽管它不使用动画对象，但它是直接内置到UIView中。改为尝试以下操作：

The iPhone supports implicit animation, though it does not use an animator object, it is built directly into UIView. Try this instead:

[UIView beginAnimations:nil context:nil];
[aView setFrame:NSMakeRect(100.0,100.0,300.0,300.0)];
[UIView commitAnimations];

确切的详细信息已记录在此处。

每个视图也始终具有图层支持，因此您不必打开图层即可获得用于显式动画的图层。

Every view is always layer backed as well, so you don;t have to turn on layers in order to get a layer for explicit animation.
