objective-c - 如何从作为 xib 的 loginviewcontroller 推送 Storyboard

Question

我有 Loginview 控制器，我用 Xib 创建了它，我想在点击登录按钮时推送 mainstoryboard。

LoginViewController *lObjloginview = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil];
UINavigationController *lObjtempview = [[UINavigationController alloc] initWithRootViewController:lObjloginview];
self.window.rootViewController = lObjtempview;
[self.window makeKeyAndVisible];

这将从xib添加登录视图。但是在按下登录按钮后我想加载故事板。任何人都可以帮助我推动mainstoryboard，它在mainstoryboard中有标签栏控制器来链接xib。

Answer 1

Load the initial view controller from the storyboard and present it

UIStoryboard * storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
UIViewController * initialVC = [storyboard instantiateInitialViewController];
self.window.rootViewController = initialVC;

If you know a priori the class you're instantiating

UITabBarController * initialVC = (UITabBarController *)[storyboard instantiateInitialViewController];
