ios - 如何在 appdelegate 中推送导航？

Question

我已经成功地实现了推送通知，但是如何从 didReceiveRemoteNotification 方法推送导航。

我的代码

Appdelegate 代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

    sleep(3);
    [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    [self registerForPushNotification:[UIApplication sharedApplication]];
    if (launchOptions != nil)
    {
        NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

        if (dictionary != nil)
        {
            NSLog(@"Launched from push notification: %@", dictionary);
            [self handlePush:application forRemoteNotification:dictionary];
        }
    }
 [self setupMainPage];
 [self.window makeKeyAndVisible];
    return YES;
}

- (void)setupMainPage
{
    if([[[NSUserDefaults standardUserDefaults] valueForKey:@"LoggedIn"] isEqualToString:@"0"])
    {
        if([[[NSUserDefaults standardUserDefaults] valueForKey:@"firstLaunch"] isEqualToString:@"0"])
        {
            [[NSUserDefaults standardUserDefaults] setObject:@"1" forKey:@"firstLaunch"];

            IntroVC *introView = [[IntroVC alloc] initWithNibName:@"IntroVC" bundle:nil];
            self.navController = [[UINavigationController alloc] initWithRootViewController:introView];
            [self.navController setNavigationBarHidden:YES];
        }
        else
        {
            LoginVC *loginVC = [[LoginVC alloc] initWithNibName:@"LoginVC" bundle:[NSBundle mainBundle]];
            self.navController = [[UINavigationController alloc] initWithRootViewController:loginVC];
        }
    }
    else
    {
        HomeVC *homeView = [[HomeVC alloc] initWithNibName:@"HomeVC" bundle:nil];
        self.navController = [[UINavigationController alloc] initWithRootViewController:homeView];
    }
    self.window.rootViewController = self.navController;
}

    - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
    {
        NSLog(@"%s",__FUNCTION__);
        NSLog(@"USER INFO - %@",userInfo);
        for (id key in userInfo)
        {
            NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);
        }

        [self handlePush:application forRemoteNotification:userInfo];
    }





  -(void)handlePush:(UIApplication *)application forRemoteNotification:(NSDictionary *)userInfo
    {
        UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
        NSLog(@"%@",userInfo);
        //NSString *pushType = [[[userInfo valueForKey:@"aps"] valueForKey:@"type"] lowercaseString];

        pushAlert = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"];
        pushType = [[userInfo valueForKey:@"aps"] valueForKey:@"type"];
        NSInteger pushBadge = [[[userInfo valueForKey:@"aps"] valueForKey:@"badge"] integerValue];
        strReciverId = [CommonUtils getNotNullString:[[userInfo valueForKey:@"aps"] valueForKey:@"receiver_id"]];
        if (pushBadge > 0) {
            [application setApplicationIconBadgeNumber:pushBadge];
        }
        // aceept request
        if ([pushType isEqualToString:@"palrequest"])
        {
            [CommonUtils alertViewDelegateWithTitle:AlertTitle
                                        withMessage:pushAlert
                                          andTarget:self
                                    forCancelString:@"View Invitation"
                               forOtherButtonString:@"Cancel"
                                            withTag:101];
        }
}



- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;

    if (alertView.tag == 101)
    {
             MyMatchesVC *myMatchesVC = [[MyMatchesVC alloc] initWithNibName:@"MyMatchesVC" bundle:nil];
             myMatchesVC.strType = pushType;
             [navigationController pushViewController:myMatchesVC animated:YES];

    }

}

推送工作完美，但我的问题是当我推送然后自动更改我的 Root View 时。

我的应用流程

1. 登录到应用程序，然后我更改了我的 Root View (Homeview Controller )
2. 现在我收到了来自其他用户的通知，然后我点击查看邀请，然后推送到我的比赛。
3. 现在我从比赛中回来，然后它变成了登录

需要这个结果

• when i back from mymatch then pop to home view controller

请帮我解决这个问题。

Answer 1

试试这个!简单的解决方案:)

if (alertView.tag == 101)
{
         MyMatchesVC *myMatchesVC = [[MyMatchesVC alloc] initWithNibName:@"MyMatchesVC" bundle:nil];
         myMatchesVC.strType = pushType;
           [self.window.rootViewController showViewController:myMatchesVC sender:self];


}

//如果你已经有了 MyMatchVC。请遵循以下样式。

  UINavigationController *snNavShareVC = (UINavigationController *)self.window.rootViewController;
    NSArray *viewControllers = snNavShareVC.viewControllers;
    UIViewController *findViewController = nil;
    for (UIViewController *vc in viewControllers) {
        NSLog(@"%@",[vc  class]);
        if ([MyMatchesVC class] == [vc class]) {
            findViewController = vc;
        }
    }
    if (findViewController) {
        [findViewController updateView:pushType]; // Write method to update view
    } else {
        MyMatchesVC *myMatchesVC = [[MyMatchesVC alloc] initWithNibName:@"MyMatchesVC" bundle:nil];
        myMatchesVC.strType = pushType;
        [self.window.rootViewController showViewController:myMatchesVC sender:self];

    }

//尝试在导航 Controller 中添加堆栈 View Controller 。

    ChatListVC *chatList = [[ChatListVC alloc]initWithNibName:@"ChatListVC" bundle:nil]; ChatDetailsVC *chatDetail = [[ChatDetailsVC alloc]initWithNibName:@"ChatDetailsVC" bundle:nil]; 
    chatDetail.strReceiverId = strReciverId; 
    NSMutableArray *controllers = [self.navController.viewControllers mutableCopy];
    [controllers addObject:chatList];
    [controllers addObject:chatDetail]; 
    [self.navigationController setViewControllers:controllers];
