iPhone开发 - 的UINavigationController可以动画视图的一部分？ [英] iphone dev - Can UINavigationController animate part of the view?

问题描述

我的应用程序使用的是导航控制器，它有一个导航栏，表视图以及每个视图的图像。这些元素从顶部布局底部没有重叠。

My app is using a navigation controller and it has a navigation bar, a table view and an image on each view. Those elements layout from top to bottom with no overlapping.

现在，因为我有完全相同的图像对每个视图（标志），是有可能的，而推意见和流行的动画只有导航栏和表视图？我想要的标志始终保持在屏幕上。

Now because I have the exactly same image for every view (a logo), is it possible to animate only the navigation bar and the table view while the views push and pop? I want the logo always stays on the screen.

先谢谢了。

推荐答案

有趣的想法。您可以尝试直接添加视图导航控制器的视图的子视图，而不是使它成为任何IT控制器的一部分管理，在这种情况下，你可能也想给查看特定标签，然后检索在各个控制器对它的引用 -viewWillAppear：动画：并调用 -bringSubviewToFront：用它导航控制器上。

Interesting idea. You might try adding the view directly as a subview of the navigation controller's view, rather than making it part of any of the controllers it manages—in that case, you probably also want to give the view a particular tag, then retrieve a reference to it in your individual controllers' -viewWillAppear:animated: and call -bringSubviewToFront: with it on the navigation controller.
