iOS 10前后推送的区别

处理远程推送消息的几种情况

app在前台时

在 iOS9 下调用：

1
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

在 iOS10 下调用：

1
2
3
4
5
6
7
8
9
10
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{
    NSDictionary * userInfo = notification.request.content.userInfo;
    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        //应用处于前台时的远程推送接受
    }else{
        //应用处于前台时的本地推送接受
    }
    //当应用处于前台时提示设置，需要哪个可以设置哪一个
 completionHandler(UNNotificationPresentationOptionSound|UNNotificationPresentationOptionBadge|UNNotificationPresentationOptionAlert);
}

app在后台时

在 iOS9 下调用：

1
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

在 iOS10 下调用：

1
2
3
4
5
6
7
8
9
//iOS10新增：处理后台点击通知的代理方法
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
    NSDictionary * userInfo = response.notification.request.content.userInfo;
    if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        //应用处于后台时的远程推送接受       
    }else{
        //应用处于后台时的本地推送接受
    }
}

app未启动的情况

在 iOS9 下调用：

1
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

其中 launchOptions 中可以获取推送消息内容，然后根据消息内容进行处理。

在iOS10系统下，app接收远程推送消息分为两步：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
//先调用
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{
    NSDictionary * userInfo = response.notification.request.content.userInfo;
    if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
        //应用处于后台时的远程推送接受
        //必须加这句代码       
    }else{
        //应用处于后台时的本地推送接受
    }
}

//然后 AppDelegate 中，launchOption 包含推送消息内容。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
  
}

最后消息数据格式的区别

//iOS9消息格式
{
  aps = {
    alert = "\U65b0\U6d88\U606f";
    ound = default;
  };
  d = us60289150408047357911;
  p = 0;
  pustId = 45267;
  pustType = 5;
}

//iOS消息格式
{
  aps = {
    alert = {
      body = sdfsfsdf;
      subtitle = xxxx;
      title = xxx;
    };
    sound = default;
  };
  d = us29253150408072030511;
  p = 0;
  pustId = 45267;
  pustType = 5;
}
