标题: iphone - 有没有办法让 App Delegate 运行条件然后选择 Storyboard入口点？

如果我使用的是 Storyboard并且入口点是 viewController1。

有没有办法让 App Delegate 运行条件，然后选择 Storyboard 入口点 - viewController1 或 viewController2？

我想从 App Delegate 中选择是否打开位置服务，然后执行以下操作:

   (![CLLocationManager locationServicesEnabled]) 
   {

        self.viewController = [[viewController1 alloc] init];

        NSLog(@"vc is viewController2 from app del. loc svcs off");

    }
    else if ([CLLocationManager locationServicesEnabled])  
    {
        // alert location services denied

        self.viewController = [[viewController2 alloc] init];

        NSLog(@"vc is viewController2 from app del. loc svcs on");

        NSLog(@"core location is on");

    }

Best Answer-推荐答案

是的，你可以这样做。

用以下方法写下你的条件:

- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions

做这样的事情

if(Con1)
{
   window.rootViewController = [window.rootViewController.storyboard instantiateViewControllerWithIdentifier"rootViewController1"];
}
else
{
    window.rootViewController = [window.rootViewController.storyboard instantiateViewControllerWithIdentifier"rootViewController2"];
}
