一 APNS推送机制
1、 官方解释如下图
推送.jpg
图中，Provider是指某个iPhone软件的Push服务器。
APNS 是Apple Push Notification Service（Apple Push服务器）的缩写，是苹果的服务器。
上图可以分为三个阶段。
第一阶段：服务器把要发送的消息、目的iPhone的标识打包，发给APNS。
第二阶段：APNS在自身的已注册Push服务的iPhone列表中，查找有相应标识的iPhone，并把消息发到iPhone。
第三阶段：iPhone把发来的消息传递给相应的应用程序， 并且按照设定弹出Push通知。
2、 详细工作流程
推送.jpg
根据图片我们可以概括一下：
a、应用程序注册APNS消息推送。
b、iOS从APNS Server获取devicetoken，应用程序接收device token。
c、应用程序将device token发送给程序的PUSH服务端程序。
d、服务端程序向APNS服务发送消息。
e、APNS服务将消息发送给iPhone应用程序。
二 注册证书
三 SDK 集成 CocoaPods
$ cd/你的项目地址
$ open -e Podfile
target 'zanqian' do
pod 'JPush', '~> 3.0.0'
end
$ pod install
四 代码示例
1、基本配置
//appdelegate.swift 遵循 JPUSHRegisterDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// 极光
if #available(iOS 10.0, *) {
let entity = JPUSHRegisterEntity()
entity.types = Int(UNAuthorizationOptions.alert.rawValue|UNAuthorizationOptions.badge.rawValue|UNAuthorizationOptions.sound.rawValue)
JPUSHService.register(forRemoteNotificationConfig: entity, delegate: self)
}else {
let types = UIUserNotificationType.badge.rawValue |
UIUserNotificationType.sound.rawValue |
UIUserNotificationType.alert.rawValue
JPUSHService.register(forRemoteNotificationTypes: types, categories: nil)
}
JPUSHService.setup(withOption: launchOptions, appKey: "", channel: "app store", apsForProduction: false)
// 获取远程推送消息 iOS 10 已取消
let remote = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? Dictionary<String,Any>;
// 如果remote不为空，就代表应用在未打开的时候收到了推送消息
if remote != nil {
// 收到推送消息实现的方法
}
//自定义消息 需要自己在receiveNotification中自己实现消息的展示
NotificationCenter.default.addObserver(self, selector: #selector(receiveNotification(notification:)), name: NSNotification.Name.jpfNetworkDidReceiveMessage, object: nil)
}
//注册APNs成功并上报DeviceToken
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
JPUSHService.registerDeviceToken(deviceToken)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
debugPrint("极光注册失败",error.localizedDescription)
}
2、代理回调
// 接收到消息回调方法
@available(iOS 10.0, *)
func jpushNotificationCenter(_ center: UNUserNotificationCenter!, willPresent notification: UNNotification!, withCompletionHandler completionHandler: ((Int) -> Void)!) {
let userInfo = notification.request.content.userInfo
if notification.request.trigger is UNPushNotificationTrigger {
JPUSHService.handleRemoteNotification(userInfo)
}else {
//本地通知
}
//需要执行这个方法，选择是否提醒用户，有Badge、Sound、Alert三种类型可以选择设置
completionHandler(Int(UNNotificationPresentationOptions.alert.rawValue))
}
@available(iOS 10.0, *)
func jpushNotificationCenter(_ center: UNUserNotificationCenter!, didReceive response: UNNotificationResponse!, withCompletionHandler completionHandler: (() -> Void)!) {
let userInfo = response.notification.request.content.userInfo
if response.notification.request.trigger is UNPushNotificationTrigger {
JPUSHService.handleRemoteNotification(userInfo)
}else {
//本地通知
}
//处理通知 跳到指定界面等等
receivePush(userInfo as! Dictionary<String, Any>)
completionHandler()
}
// iOS 9.0
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
JPUSHService.handleRemoteNotification(userInfo);
completionHandler(UIBackgroundFetchResult.newData);
}
3、推送处理
func receivePush(_ userInfo : Dictionary<String,Any>) {
//根据服务器返回的字段判断
let userInfo = userInfo["key"] as! String
let jsonData:Data = userInfo.data(using: .utf8)!
var dict = try! JSONSerialization.jsonObject(with: jsonData, options: .allowFragments) as! [String:AnyObject]
let messageJson = JSON(dict ["data"]!)
let message = Message.init(json: messageJson)
if message.type == 2
{
let rootView = getRootViewController()
rootView.pushViewController(MessageViewController.init(type: 2), animated: true)
}
// 角标变0
UIApplication.shared.applicationIconBadgeNumber = 0
}
//获取当前页面的是控制器
func getRootViewController () ->(UINavigationController)
{
let rootViewController = UIApplication.shared.keyWindow?.rootViewController
if (rootViewController?.isKind(of: TabBarViewController.self))!
{
//let firstController = rootViewController?.childViewControllers[tabBarController.selectedIndex]
let firstController = tabBarController.selectedViewController
if (firstController?.isKind(of: UINavigationController.self))! {
return firstController as! UINavigationController
}else
{
return UINavigationController.init(rootViewController: firstController!)
}
}else if (rootViewController?.isKind(of: UINavigationController.self))!
{
return rootViewController as! UINavigationController
}
return UINavigationController.init(rootViewController: rootViewController!)
}
func applicationDidBecomeActive(_ application: UIApplication) {
//角标至0
UIApplication.shared.applicationIconBadgeNumber = 0
}
如有不妥，请多多指教。
