ios7 Storyboard UIViewController(first ViewController,root ViewController)

取消 Is Initial View Controller 的勾勾

設定Storyboard ID

刪除 Main Interface 內的文字

程式啟動時第一個 UIViewController welcomeStoryboard

// in AppDelegate.m

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

{

    self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

    UIViewController *firstViewController = [storyboard instantiateViewControllerWithIdentifier:@"welcomeStoryboard"];

    self.window.rootViewController = firstViewController;

    [self.window makeKeyAndVisible];

    return YES;

}

後續想轉跳的UIViewController myStoryboard

// in ViewController.m

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

UIViewController *view = [storyboard instantiateViewControllerWithIdentifier:@"myStoryboard"];

[view setModalPresentationStyle:UIModalPresentationFullScreen];

[self presentViewController:view animated:NO completion:nil];
