怎么在每个视图控制器上创建导航控制器

Question

我在分栏控制器上加了4个视图控制器，只能在根视图控制器上加导航控制器，分栏控制器上的每个视图控制器都加上导航控制器，怎么做。

Answer 1

每一个viewController都得有一个UINavigationController 就行了，类似我下面的写法就行了

 HomePageVC * HomeVC = [[HomePageVC alloc] init];
    UINavigationController * HomeNav = [[UINavigationController alloc] initWithRootViewController:HomeVC navigationBarBackgroundColor:backGroudColor];

    ChatSessionVC *msgVC = [[ChatSessionVC alloc] init];
    UINavigationController *msgNav = [[UINavigationController alloc]initWithRootViewController:msgVC navigationBarBackgroundColor:backGroudColor];

    FindHomeVC * FindVC = [[FindHomeVC alloc] init];
    UINavigationController * FindNav = [[UINavigationController alloc] initWithRootViewController:FindVC navigationBarBackgroundColor:backGroudColor];

    MineVC * UserVC = [[MineVC alloc] init];
    UINavigationController * UserNav = [[UINavigationController alloc] initWithRootViewController:UserVC navigationBarBackgroundColor:backGroudColor];
    [UserNav setNavigationBarHidden:YES];

    NSArray *tabArray = @[HomeNav,msgNav,FindNav,UserNav];
