ios - UITabBar 中的 UITableViewController

Question

我正在尝试围绕我的 UITableView Controller 创建一个 UITabBarController。我正在使用这段代码。但问题是，当使用它时，导航栏消失了。我该如何解决这个问题？

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
StyledTableViewController *viewController1 = [[StyledTableViewController alloc] initWithNibName:@"StyledTableViewController" bundle:nil];

self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = @[viewController1];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;

需要将 UINavigationController 添加到 Navigation Bar 并且它会维护您的 View 层次结构

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
StyledTableViewController *viewController1 = [[StyledTableViewController alloc] initWithNibName:@"StyledTableViewController" bundle:nil];
 UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:viewController1];

self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = @[navController];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
