Swift - JPush极光推送的使用4（根据Tag标签，给同一类别用户发推送）

一、标签（tag）介绍
（1）前文讲的别名（alias）是为了对每一个用户进行标识。而标签（tag）是用来将用户分类分组，这样便于批量推送消息。
（2）可为每个用户打多个标签。（比如： vip、women、game 等等）
（3）不同应用程序、不同的用户，可以打同样的标签。
四、完整代码
1，客户端代码

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    var window: UIWindow?
    
    func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions
                        launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
      
        //通知类型（这里将声音、消息、提醒角标都给加上）
        let userSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound],
                                                      categories: nil)
        if ((UIDevice.current.systemVersion as NSString).floatValue >= 8.0) {
            //可以添加自定义categories
            JPUSHService.register(forRemoteNotificationTypes: userSettings.types.rawValue,
                                                            categories: nil)
        }
        else {
            //categories 必须为nil
            JPUSHService.register(forRemoteNotificationTypes: userSettings.types.rawValue,
                                                            categories: nil)
        }
        
        // 启动JPushSDK
        JPUSHService.setup(withOption: nil, appKey: "7b96331738ea713195698fd",
                                     channel: "Publish Channel", apsForProduction: false)

        return true
    }
 
    
    func application(_ application: UIApplication,
                     didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        //注册 DeviceToken
        JPUSHService.registerDeviceToken(deviceToken)
    }
    
    func application(_ application: UIApplication,
                     didReceiveRemoteNotification userInfo: [AnyHashable : Any],
                     fetchCompletionHandler
                        completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        //增加IOS 7的支持
        JPUSHService.handleRemoteNotification(userInfo)
        completionHandler(UIBackgroundFetchResult.newData)
    }
    
    func application(_ application: UIApplication,
                     didFailToRegisterForRemoteNotificationsWithError error: Error) {
        //可选
        NSLog("did Fail To Register For Remote Notifications With Error: \(error)")
    }
    
    //..........
}

（2）ViewController.swift（标签注册相关）

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var switch1: UISwitch!
    @IBOutlet weak var switch2: UISwitch!
    @IBOutlet weak var switch3: UISwitch!
    @IBOutlet weak var textView: UITextView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    //按钮点击
    @IBAction func btnTouchUp(sender: AnyObject) {
        //获取标签
        var tags = Set<NSObject>()
        if switch1.on {
            tags.insert("movie")
        }
        if switch2.on {
            tags.insert("music")
        }
        if switch3.on {
            tags.insert("game")
        }
        
        //注册标签
        JPUSHService.setTags(tags,
                              callbackSelector: #selector(tagsAliasCallBack(_:tags:alias:)),
                              object: self)
    }
    
    //标签注册回调
    func tagsAliasCallBack(resCode:CInt, tags:NSSet, alias:NSString) {
        textView.text = "响应结果：\(resCode)"
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

2，服务端代码（index.php）

<?
//引入代码
require 'JPush/autoload.php';

use JPush\Client as JPush;

if(isset($_POST["message"])){
  //初始化
  $app_key = "7b528333738ec729165798fd";
  $master_secret = "32da4e2c36957b247a2c9828";
  $client = new JPush($app_key, $master_secret);

  //将逗号隔开的字符串拆分成标签数组
  $tags = explode(',', $_POST["tags"]);

  //简单的推送样例
  $result = $client->push()
      ->setPlatform('ios', 'android')
      ->addTag($tags)
      ->setNotificationAlert($_POST["message"])
      ->options(array(
          "apns_production" => true  //true表示发送到生产环境(默认值)，false为开发环境
        ))
      ->send();

  echo 'Result=' . json_encode($result);
}
