iphone - 如何卸载 Storyboard？

Question

我需要卸载 Storyboard并用另一个 View Controller 替换 Root View Controller 。当我完成另一个 View Controller 时，我需要卸载他并恢复 Storyboard和 Root View Controller 。当我尝试替换 Root View Controller 时， Storyboard仍然与其他 View 一起存在。

Answer 1

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

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

当你希望storyBoard在desiredViewController之后接管时..

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 ];
