【问题描述】：

我的应用程序处于未运行状态我点击通知其打开的主页但我想打开特定页面，但它适用于应用程序处于前台和后台时，但我在应用程序委托的一种方法中编写了此代码警报视图显示所有状态。

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)())completionHandler
         

          NSDictionary *userInfo = response.notification.request.content.userInfo;
           NSDictionary *dict = userInfo[kAps];
           NSString *str = [NSString stringWithFormat:@"%@",[dict valueForKey:kAlert]];
           UINavigationController *navController = (UINavigationController *)self.window.rootViewController;
           MyOrderDetailVC *view =  [[UIStoryboard storyboardWithName:kMainStoryboard bundle:nil] instantiateViewControllerWithIdentifier:@"MyOrderDetailVC"];

           NSString *orderstatus = userInfo[kgcmnotificationorderstatus];
           NSString *ordertype = userInfo[kgcmnotificationordertype];
           view.isFromSideMenu = YES;
           view.isfromViewOrders = YES;
           view.status =  orderstatus;  //[NSString stringWithFormat:@"%@",[dictOrderDetails valueForKey:korderstatus]];
           view.isProduct =ordertype;
           view.strOrderStatus = orderstatus;
           view.strProgramId = @"-1";
           if([ordertype isEqualToString: @"0"])
           
           view.isBookedOrders = NO;
           
           if([ordertype isEqualToString: @"1"])
           
             view.isBookedOrders =YES;
           
           if([orderstatus isEqualToString:@"0"])
           
             view.strOrderStatus = kPending;
           
           else if([orderstatus isEqualToString:@"1"])
           
             view.strOrderStatus = kConfirmed;
           
           else if ([orderstatus isEqualToString:@"2"])
           
             view.strOrderStatus = kCompleted;
           
           [navController.visibleViewController.navigationController pushViewController:view animated:YES];

     [[Shared sharedInstance] showAlertViewInViewController:kAppName message:str buttonTitles:@[OK] viewC:self.window.rootViewController handler:nil];

【参考方案1】：

当您的应用未运行并且您想在didFinishLaunchingWithOptions 方法中检测您的Notification 时，如下所示

-(BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
    
  UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];    
  if (localNotif) 
     // Notification detect here
     // Put your code here so it will be call when your App will not running state and tapped on Notification.
      

【讨论】：

但它会“- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler”这个方法，因为它显示警报视图在此方法中调用，但不导航到仅在此方法中写入的其他页面。

您可以通过 if ( application.applicationState == UIApplicationStateInactive) //当应用在后台时从推送通知中打开

获取应用状态

【参考方案2】：

在 didFinishLaunchingWithOptions 检查通知是或注意

NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (notification)

    NSLog(@"app recieved notification %@",notification);
  // open your particular controller


else
    NSLog(@"app did not recieve  notification");

我试过这个，但当我点击通知时，它会转到主页并显示警报视图，但不会导航到特定页面。

你可以打开 partilcaur 视图控制器作为这个 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil]; Yourcontroller *myVC = (Yourcontroller *)[storyboard instantiateViewControllerWithIdentifier:@"YourcontrollerId"]; [self.navigationController pushViewController: myVC animated:YES];
