本文详细介绍了iOS开发中模态视图、UITabBarController实现并列画面跳转及UINavigationController实现多层画面跳转的用法，通过实例展示了如何在导航控制器和Tab控制器中进行界面切换。

1.模态视图

-(void)presentModel
{
RootViewController *rootview = [[RootViewController alloc]init];

rootview.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:rootview animated:YES completion:^{
    NSLog(@"call back");
}];

}

2,UITabBarController实现并列画面跳转

self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];

UIViewController *vc1 = [[UIViewController alloc]init];
vc1.title = @"消息";
vc1.view.backgroundColor = [UIColor redColor];
UIViewController *vc2 = [[UIViewController alloc]init];
vc2.title = @"设置";
vc2.view.backgroundColor = [UIColor orangeColor];
UIViewController *vc3 = [[UIViewController alloc]init];
vc3.title = @"主页";
vc3.view.backgroundColor = [UIColor yellowColor];
UIViewController *vc4 = [[UIViewController alloc]init];
vc4.title = @"微博";
vc4.view.backgroundColor = [UIColor greenColor];
UIViewController *vc5 = [[UIViewController alloc]init];
vc5.title = @"图片";
vc5.view.backgroundColor = [UIColor blueColor];

NSArray *controller = @[vc1,vc2,vc3,vc4,vc5];
UITabBarController *tabbar = [[UITabBarController alloc]init];
tabbar.viewControllers = controller;

3,UINavigationController实现多层画面跳转，在导航控制器中，载入有层级关系的界面

-(void)pushNavigation
{
SecondViewController *controller2 = [[SecondViewController alloc]init];
[self.navigationController pushViewController:controller2 animated:YES];
}

-(void)index
{
UIViewController *second = [[self.navigationController viewControllers]objectAtIndex:1];
[self.navigationController popToViewController:second animated:YES];
}
注：UInavigationController中各视图之间有层级关系，用栈的模式来管理视图控制器，而UITabBarController中各视图之间是并列关系，无层级之分。
两者混合使用时最好将UINavigationController加到UITabBarController上！
