核心动画 - 片状窗口滑动 [英] Core Animation - Sheet-like Window Sliding

问题描述

使用核心动画使NSView幻灯片在视图外如何难以使用？一般来说，完成这项工作将涉及什么？我一直在阅读CA文档，但是我很难确定哪些部分与我想做的事情相关，因为我没有框架的经验。

解决方案

因为你在谈论NSView，你可能使用Cocoa的动画支持，而不是直接使用CA。在这种情况下，您只需要通过视图的animator对象设置视图的框架：

  [theView setFrame：offscreenFrame]; 
 [[theView animator] setFrame：finalFrame];不幸的是，Cocoa视图动画与CA的更高级功能（例如设置缓动）相互影响，这是非常不利的。。
 



。你可能有更多的运气使用NSViewAnimation，而不是核心动画支持，并允许一点更多的灵活性。

How difficult would it be to use core animation to make an NSView slide in an out of view like a sheet? Generally speaking, what would be involved in accomplishing this? I've been reading through the CA documentation, but it's been hard for me to pinpoint which parts are relevant to what I want to do since I have no experience with the framework.

Any tips at all would be much appreciated.

Thanks.

解决方案

Since you're talking of a NSView, you're probably using Cocoa's animation support, not CA directly. In this case, you just need to set the view's frame through the view's animator object:

[theView setFrame:offscreenFrame];
[[theView animator] setFrame:finalFrame];

Unfortunately, Cocoa view animation interacts badly with the more advanced features of CA, like setting an easing. You might have more luck using NSViewAnimation instead, which is not Core Animation-backed and allows for a little more flexibility.
