如何卸载故事板？

Question

我需要卸载故事板并用另一个视图控制器替换根视图控制器。当我完成另一个视图控制器时，我需要卸载他并恢复故事板和根视图控制器。当我尝试替换根视图控制器时，故事板仍然可以与其他视图一起使用。

Answer 1

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

中的

{
UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:DesiredViewController];
}

当你想让storyBoard接管到desiredViewController之后......

使用desiredViewController中的代码

AppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
 UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; //MainStoryBoard is the name of your storyBorad
        UIViewController* myStoryBoardInitialViewController = [storyboard instantiateInitialViewController];

        [appDelegate.window setRootViewController:myStoryBoardInitialViewController ];
