アラート ビューを介して AppDelegate からビュー コントローラーにプッシュしたいと考えています。しかし、うまくいきません。アラート ビューのみが閉じます。問題はどこだ？助けてくれてありがとう。(注 > 私の最初のビューはストーリーボードにありますが、ビュー コントローラーのペン先に押し込んでいます)

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

loginReapeat = [NSTimer scheduledTimerWithTimeInterval:60.0 target:self selector:@selector(repeatLoginProcess) userInfo:nil repeats:YES];

//First Launch Settings
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"FirstLaunch"])
{

}
else
{
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"FirstLaunch"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    [self alertShow];
}

[window addSubview:[navigationController view]];

[window makeKeyAndVisible];

return YES;
} 

-(void)alertShow{

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Help!" message:@"Need some help to use this App? Please tap the 'Help' button." delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Help",nil];
[alert show];
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
if([title isEqualToString:@"Help"])
{
    SignUp *signUp = [[SignUp alloc]initWithNibName:@"SignUp" bundle:nil];

    [self.navigationController pushViewController:signUp animated:YES];

}
}

これを試して：

SignUp *signUp = [[SignUp alloc]initWithNibName:@"SignUp" bundle:nil];                
self.navigationController = [[UINavigationController alloc] initWithRootViewController:signUp];
self.window.rootViewController = self.navigationController;

    SignUp *signUp = [[SignUp alloc]initWithNibName:@"SignUp" bundle:nil];                
   UINavigationController *masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:signUp ] autorelease];
    self.window.rootViewController = masterNavigationController;

App Delegate 内からプッシュすることはできません。代わりにUIViewController、ユーザーがUIAlertView.

self.window.rootViewController = self.navController;

[self.window makeKeyAndVisible];
return YES;
