首次启动时viewDidLoad中的presentModalViewController [英] presentModalViewController in viewDidLoad on first launch

问题描述

我一直在寻找，但遗憾的是没有运气。

I've been searching around but unfortunately have had no luck.

我的应用要求用户在他或她启动时首次登录/注册应用程序。我知道如何确定首次启动（使用NSUserDefaults），但每当我尝试呈现包含登录/注册控件的模态时，都没有任何反应。

My app requires the user to sign in/sign up the first time he or she launches the app. I know how to determine first launch (using NSUserDefaults) but whenever I try to present the modal containing the sign in/ sign up controls, nothing happens.

这是我的拥有：

-(void)viewDidLoad {
    [self showLogin];
    [super viewDidLoad];
}

-(void)showLogin {    
    FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"AccountView" bundle:nil];
    controller.delegate = self;

    controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:controller animated:YES];

    [controller release];
}

然而，没有任何反应。主视图正常加载。非常感谢任何帮助。

However, nothing happens. The main view just loads as normal. Any help is greatly appreciated.

[UPDATE]

只需使用..

-(void)viewDidAppear:(BOOL)animated 
{

}

而不是

-(void)viewDidLoad
{

}

非常感谢！
