Question

我刚刚开始学习如何使用iOS和Parse实现推送通知。目前，我可以从Parse仪表板向应用程序发送推送通知，收到通知，正如我在Xcode控制台中看到的那样，但现在我的问题是我无法从AppDelegate打开视图控制器。

这是我的代码：

- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler {
    // Create empty photo object
    NSString *photoId = [userInfo objectForKey:@"p"];
    NSLog(@"P=%@",photoId);


    UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
    Aceptado *targetViewController = (Aceptado*)[mainStoryboard instantiateViewControllerWithIdentifier:@"servicio_aceptado"];
    UINavigationController *controlador = [[UINavigationController alloc]init];
    [controlador pushViewController:targetViewController animated:YES];

    }

正如我所说，控制台显示日志NSLog(@"P=%@",photoId)，收到通知，但未显示视图控制器，显示任何警告或错误。

欢迎任何帮助。

我已经解决了这个问题：

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

    Aceptado *controller = (Aceptado*)[mainStoryboard
                                                       instantiateViewControllerWithIdentifier: @"servicio_aceptado"];
        controller.id_not =_id_not;
        controller.idemployee = _idemployee;
        controller.fullname = _fullname;
        controller.phone = _phone;
        controller.photo = _photo;
        controller.dni = _dni;
        controller.licenseplate = _licenseplate;
        controller.model = _model;
        controller.color = _color;
        controller.latitude = _latitude;
        controller.longitude = _longitude;

    self.window.rootViewController = controller;

现在我可以从AppDelegate文件向目标视图控制器传递值，保留SWRevealViewController结构。感谢大家的提议。

您不应该创建新的NavigationController，而是使用一个现有的。通常它是关键窗口的 rootViewController 属性。

试试这个：

UINavigationController *controlador = self.window.rootViewController;

如果要在SWRevealViewController中显示 targetViewController ，可以更改代码：

SWRevealViewController *controlador = (SWRevealViewController)self.window.rootViewController;
[controloador pushFrontViewController:targetViewController animated:YES];

如果您需要在SWRevealViewController上显示 targetViewController ，请使用：

WRevealViewController *controlador = (SWRevealViewController)self.window.rootViewController;
[controloador presentViewController:targetViewController
                 animated:YES
               completion:nil];

如果您只需要用 targetViewController 替换SWRevealViewController，请使用：

self.window.rootviewController=targetViewController;

但请不要忘记将SWRevealViewController保存在其他属性中。

试试这段代码。

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
Aceptado *targetViewController = (Aceptado*)[mainStoryboard instantiateViewControllerWithIdentifier:@"servicio_aceptado"];

UINavigationController *navVc=(UINavigationController *) self.window.rootViewController;

[navVc pushViewController: targetViewController animated:YES];

可以帮到你。

Answer 4

尝试一次。

UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
Slider1ViewController *viewcontroller = [storyBoard instantiateViewControllerWithIdentifier:@"Slider1ViewController"];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewcontroller];
[navController setViewControllers: @[viewcontroller] animated: YES];

[self.revealViewController setFrontViewController:navController];
[self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];

Answer 5

试试这个：

SomePageViewController *someVC = [self.storyboard instantiateViewControllerWithIdentifier:@"SomeVC"];

self.navController = [[UINavigationController alloc] initWithRootViewController:someVC];
self.window.rootViewController = self.navController;

[self.window makeKeyAndVisible];

如果要将视图控制器从appDelegate推入导航堆栈，则需要将rootView控制器转换为UINavigation Controller

从AppDelegate推送视图控制器
