iphone - 在 iPhone 应用程序中显示加载视图并切换到 TabBarController

Question

我正在开发一个带有两个选项卡的 TabBarController 的 iPhone 应用程序。
每个选项卡都包含一个从我的网站加载网页的 UIWebView。

我想添加一个视图，该视图将用作不显示 TabBarController 本身（全屏视图）并指示正在加载应用程序的欢迎屏幕。
之后我想隐藏欢迎屏幕并显示 TabBarController

谁能指出我如何实现此功能的正确方向？

谢谢！

I would suggest using a modal view controller for the loading view:

- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated

If you present the modal view controller as soon as your app launches (with no animation), it will be on top of everything, including the tab bar, even if it was presented by one of the tab view controllers.

Once the loading is done, you can dismiss the modal view controller:

- (void)dismissModalViewControllerAnimated:(BOOL)animated

You could animate the dismissal or not.

If your Default.png (launch screenshot) looks like the modal view, the whole thing should be pretty seamless.
