如何在iPhone中创建可配置的标签栏（例如音乐应用）

Question

我想在我的应用程序（如iPhone音乐应用程序）中实现可配置的标签栏，用户可以通过在其中拖放图标来编辑标签栏。

Answer 1

Well, then it's a good thing that UITabBar has this functionality built in. Take a look at the following method:

UITabBar *mybar = [[UITabBar alloc] init];
[mybar beginCustomizingItems:[NSArray arrayWithObjects:tabItem1, tabItem2, nil]];

Answer 2

UITabBarController handles this completely automatically. If you add more than 5 tabs to the tab controller then the fifth button changes to 'More' to allow the user to access the configuration interface.

If you want to customise the behaviour or do something completely different then implement the UITabBarDelegate protocol.
