在我发送推送通知后，我希望应用程序在我的收件箱页面上打开，以便用户可以在收件箱中看到新消息。我的 AppDelegate 中有以下代码

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

    [self.tabController setSelectedIndex:2]; 
}

当我发送推送消息并且手机处于活动状态时，它会直接进入那里而不会发出警告。我知道这就是我的代码应该做的，但是有没有办法像这样改变它

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

    if(app.isActive == FALSE)
          [self.tabController setSelectedIndex:2]; 
}

对此的任何见解都会有很大帮助。谢谢！

来自 Stanislav Yaglo，目标 C：如何检查应用程序当前是否处于活动状态（即用户正在使用它）？：

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

    if (application.applicationState == UIApplicationStateActive) {
        // For example, update the tab bar
    }
    else {
        self.tabController.selectedIndex = 3;
    }
}

希望能帮助到你 ！

YES进入应用程序后，您可以设置一个布尔值，只需将布尔值设置为：

- (void)applicationWillEnterForeground:(UIApplication *)application

并将布尔值设置NO为

- (void)applicationDidEnterBackground:(UIApplication *)application

You can tell if the application was in the foreground by checking the applicationState like so:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateActive )
        // app is in the foreground
    else
        // app was just brought from background to foreground
    ...
}
