收到推送通知时打开特定的标签栏 [英] Open specific tab bar when receive push notification

问题描述

在收到推送通知时如何打开特定的标签栏？

How can i open specific tab bar when receive push notification?

我已经放置了 [self.tabBarController setSelectedIndex：2]; 放在viewDidAppear上，发生的是数据记录，它显示它通过tabBar 2 viewController传递，但没有打开/显示该页面，而是停留在firstView控制器/第一个tabBar上。

i already put [self.tabBarController setSelectedIndex:2];on viewDidAppear and what happen is in data logging, it showing that it passing through tabBar 2 viewController but it not open/showing that page and remain at the firstView controller/ first tabBar.

，然后在我终止应用程序并重新打开后，自动/突然打开tabBar 2 viewController。

and then after i terminate the app and open back, automatically/ suddenly it open the tabBar 2 viewController.

任何人都可以提出任何想法或示例代码来解决这个问题？

can anyone give any idea or sample code to solve this?

这是在我的didReceiveRemoteNotification中；

this is in my didReceiveRemoteNotification;

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

    NSLog(@"Remote notification received");

    if([userInfo valueForKey:@"app"]) {

        NSString *action_app = [userInfo valueForKey:@"app"];
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        [defaults setObject:action_app forKey:@"app"];

        NewVC *sample=[[NewVC alloc]init];
        [sample viewDidLoad];

        //[self.tabBarController setSelectedIndex:2];

        [self clearNotifications];

    }else{

        NSLog(@"---nothing to read---");
    }
}

NewVC位于选项卡栏2。

NewVC are located at tabbar 2.

推荐答案

您必须更改tabbar selectedIndex，例如

You have to change tabbar selectedIndex like,

- (void)application:(UIApplication *)application  didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if([userInfo valueForKey:@"app"]) {

      NSString *action_app = [userInfo valueForKey:@"app"];
      NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
     [defaults setObject:action_app forKey:@"app"];

   UITabBarController *tabb = (UITabBarController *)self.window.rootViewController;
   tabb.selectedIndex = 2;
 }
}
