應用第一次啓動，修改rootViewController方法

1、第一次設置

C代碼  

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
NewEntryController *controller = [[NewEntryController alloc] initWithNibName:@"NewEntryController" bundle:nil];
self.window.rootViewController = [[GKNavigationController alloc] initWithRootViewController:controller];
[self.window makeKeyAndVisible];
return;

 

2、修改rootViewController

C代碼  

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
// 在delegate中初始化新的controller
[delegate initTabbarController];
// 修改rootViewController
[delegate.window addSubview:delegate.tabbarController.view];
[self.view removeFromSuperview];
delegate.window.rootViewController = delegate.tabbarController;
