UITabBarController详解(二)UITabBarController的代理方法以及模态显示
最后更新于：2022-04-01 06:58:49
@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{
}
