Question

当用户点击远程通知时，会在app delegate中触发以下回调：

-application:didReceiveRemoteNotification:fetchCompletionHandler:

在此方案中，应用程序已启动，应用程序状态为UIApplicationStateActive，我将其解释为用户对远程通知执行操作。

问题： 当远程通知到达并且app处于前景且处于非活动状态时，也可以调用此方法。

示例：当通知中心视图打开时（从屏幕上边缘向下滑动）或UIAlert打开。在这两种情况下，应用程序状态都是UIApplicationStateActive，并且无法判断它是否是收到的用户操作通知或系统推送。

问：如何确定didReceiveRemoteNotification回调是否响应用户点击远程通知与远程通知的到达？

Answer 1

UIApplicationState state = [application applicationState];
     if (state == UIApplicationStateActive)
     { 
          //When your app is in foreground and it received a push notification
     }
     else if (state == UIApplicationStateInactive) 
     {
          //When your app was in background and it received a push notification
     }

此外，如果应用程序未运行且用户点击了通知，则会调用didFinishLaunchingWithOptions。我没有尝试过，但我可以假设您可以从选项中获取通知详细信息。

要区分didReceiveRemoteNotification中的两个调用，您可以从下面添加此代码。

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
{


if ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive) {

    [[NSNotificationCenter defaultCenter] postNotificationName:@“inactivePush" object:nil];


}

else if([UIApplication sharedApplication].applicationState==UIApplicationStateActive){



    [[NSNotificationCenter defaultCenter] postNotificationName:@"appOpenPush" object:nil];


}

//When the app is in the background
else {



}//End background

}

}
