我想通过警报视图从AppDelegate推送到视图控制器。但它不起作用。只有警报视图才会解散。问题出在哪儿?在此先感谢您的帮助。 (N.B>我的初始视图在故事板中,但我正在推动视图控制器笔尖)
- (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];
}
}

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

您无法从App Delegate中进行推送,而是可以根据用户从UIViewController
的选择决定将哪个UIAlertView
显示为rootviewcontroller。
self.window.rootViewController = self.navController;
答案 2 :(得分:0)
SignUp *signUp = [[SignUp alloc]initWithNibName:@"SignUp" bundle:nil];
UINavigationController *masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:signUp ] autorelease];
self.window.rootViewController = masterNavigationController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
ViewControllerName *home=[[ViewControllerName alloc] initWithNibName:@"ViewControllerName" bundle:nil];
self.window.rootViewController=home;
navcontroller=[[UINavigationController alloc]initWithRootViewController:home];
self.window.rootViewController = self.navController.view;
[self.window makeKeyAndVisible];
return YES;
