iOS 推送通知流程

Question

我正在处理推送通知流程，但不知道如何处理它。我需要一个简单的解释，当推送通知到来时，调用哪个委托

1. 当用户点击推送通知标签时
2. 当用户在推送通知到来时点击应用图标时

我无法维持我的应用程序状态，对我来说流程应该是这样的：

1. 当用户点击推送通知标签时：它应该打开一个特定的视图控制器
2. 当用户在推送通知时点击应用程序图标时：它应该从应用程序在后台打开相同的视图控制器

如何在 Xcode 8.1/iOS 10.1.1 中实现这一点？

我也在使用后台模式远程通知和后台获取。

Answer 1

在 AppDelegate.m 中使用它来检查用户点击图标的位置

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    //Handle notification when the user click it while app is running in background or foreground.
    if(application.applicationState == UIApplicationStateInactive) {

        NSLog(@"Inactive - the user has tapped in the notification when app was closed or in background");
        //do some tasks


    }
    else if (application.applicationState == UIApplicationStateBackground) {

        NSLog(@"application Background - notification has arrived when app was in background");

    }
    else {
        NSLog(@"application Active - notication has arrived while app was opened");

        //do tasks


    }


}

当推送通知从服务器发送应用端的委托调用，但您必须通过添加 registerForPushNotifications 从应用端注册。

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

    //Handle notification when the user click it while app is running in background or foreground.


    //Where userinfo is a dict. It has the data sent from server

  }
