如何更改第一次加載視圖

Question

我在didFinishLaunching上獲得了此代碼，但我不知道如何自定義它以從打開應用程序時打開menuViewController。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions 
{ 
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
// Override point for customization after application launch. 
self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease]; 


self.window.rootViewController = self.viewController; 
[self.window makeKeyAndVisible]; 
// At the end of applicationDidFinishLaunching, right before 
// the return YES 
[[GCTurnBasedMatchHelper sharedInstance] authenticateLocalUser]; 
return YES; 
} 

希望有人能幫助我

Answer 1

更改以下行

self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease]; 

到

self.viewController = [[[menuViewController alloc] initWithNibName:@"menuViewController" bundle:nil] autorelease]; 

Answer 2

您需要更改該生產線是

self.window.rootViewController = self.viewController; 

要

MenuViewController *menuViewController = [[[MenuViewController alloc] init] autorelease]; 
self.window.rootViewController = menuViewController; 

這是假設你有一個名爲MenuViewController

Answer 3

創建的menuViewController對象該控制器分配給rootViewController自定義視圖控制器。

self.viewController = [[[MenuViewController alloc] initWithNibName:@"menuViewController" bundle:nil] autorelease]; 

self.window.rootViewController = self.viewController; 
[self.window makeKeyAndVisible];
