UITabBarController详解(二)UITabBa

@首先要实现协议

//设置代理

tabBarController.delegate =self; 

//UINavigationController nav tabBarController.moreNavigationController;

//[nav setNavigationBarHidden:YES animated:YES];

//控制哪些ViewController的标签栏能被点击

-(BOOL)tabBarController:(UITabBarController)tabBarControllershouldSelectViewController:(UIViewController)viewController{

//代表HMT_CViewController这个View无法显示,无法点击到它代表的标签栏

if([viewControllerisKindOfClass:[HMT_CViewControllerclass]]) {
    returnNO;
}
    returnYES;
}

// 选中哪个标签栏,一个监控作用吧

(void)tabBarController:(UITabBarController *)tabBarControllerdidS    electViewController:(UIViewController*)viewController{
}

// More view controller将要开始编辑
(void)tabBarController:(UITabBarController)tabBarControllerwillBe    ginCustomizingViewControllers:(NSArray)viewControllers{
}

// More view controller将要结束编辑

(void)tabBarController:(UITabBarController)tabBarControllerwillEn    dCustomizingViewControllers:(NSArray)viewControllers              changed:(BOOL)changed{
}

// More view controller编辑

(void)tabBarController:(UITabBarController)tabBarControllerdidEnd    CustomizingViewControllers:(NSArray)viewControllers                   changed:(BOOL)changed{
}
