UITabBarController详解(二)UITabBarController的代理方法以及模态显示

@首先要实现协议<UITabBarControllerDelegate>

    //
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 *)tabBarControllerdidSelectViewController:(UIViewController *)viewController{

}

// More view controller将要开始编辑
- (void)tabBarController:(UITabBarController *)tabBarControllerwillBeginCustomizingViewControllers:(NSArray
*)viewControllers{

}
// More view controller将要结束编辑
- (void)tabBarController:(UITabBarController *)tabBarControllerwillEndCustomizingViewControllers:(NSArray *)viewControllers
changed:(BOOL)changed{

}
// More view controller编辑
- (void)tabBarController:(UITabBarController *)tabBarControllerdidEndCustomizingViewControllers:(NSArray *)viewControllers
changed:(BOOL)changed{

}
