如何在 Swift 中设置推送通知 [英] How to set up push notifications in Swift

问题描述

我正在尝试为我的应用程序设置推送通知系统.我有一个服务器和一个开发者许可证来设置推送通知服务.

I am trying to set up a push notification system for my application. I have a server and a developer license to set up the push notification service.

我目前正在 Swift 中运行我的应用.我希望能够从我的服务器远程发送通知.我该怎么做?

I am currently running my app in Swift. I would like to be able to send the notifications remotely from my server. How can I do this?

推荐答案

虽然解决了推送通知的问题，但我仍然相信立即分享集成完整案例以缓解:

While the answer is given well to handle push notification, still I believe to share integrated complete case at once to ease:

为APNS注册应用程序，(在AppDelegate.swift中的didFinishLaunchingWithOptions方法中包含以下代码)

To Register Application for APNS, (Include the following code in didFinishLaunchingWithOptions method inside AppDelegate.swift)

IOS 9

var settings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes:UIUserNotificationType.Alert|UIUserNotificationType.Sound, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()

IOS 10 之后

引入了 UserNotifications 框架:

Introduced UserNotifications framework:

导入 UserNotifications 框架并在 AppDelegate.swift 中添加 UNUserNotificationCenterDelegate

Import the UserNotifications framework and add the UNUserNotificationCenterDelegate in AppDelegate.swift

注册 APNS 应用程序

To Register Application for APNS

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in

    // If granted comes true you can enabled features based on authorization.
    guard granted else { return }

    application.registerForRemoteNotifications()
}

这将调用以下委托方法

func application(application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
//send this device token to server
}

//Called if unable to register for APNS.
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {

println(error)

}

收到通知后，以下代表将调用:

On Receiving notification following delegate will call:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    println("Recived: \(userInfo)")
   //Parsing userinfo:
   var temp : NSDictionary = userInfo
   if let info = userInfo["aps"] as? Dictionary<String, AnyObject> 
            {
                var alertMsg = info["alert"] as! String
                var alert: UIAlertView!
                alert = UIAlertView(title: "", message: alertMsg, delegate: nil, cancelButtonTitle: "OK")
                alert.show()
            }
}

要确定我们可以使用的权限:

To be identify the permission given we can use:

UNUserNotificationCenter.current().getNotificationSettings(){ (setttings) in

        switch setttings.soundSetting{
        case .enabled:
            print("enabled sound")

        case .disabled:
            print("not allowed notifications")

        case .notSupported:
            print("something went wrong here")
        }
    }

APNS 的清单:

• 创建允许推送通知的 AppId
• 使用有效的证书和应用程序 ID 创建 SSL 证书
• 使用相同的证书创建配置文件，并确保在沙盒(开发配置)的情况下添加设备

注意:如果在 SSL 证书之后创建配置文件会很好.

Note: That will be good if Create Provisioning profile after SSL Certificate.

使用代码:

• 注册应用以获得推送通知
• 处理 didRegisterForRemoteNotificationsWithDeviceToken 方法
• 设定目标>能力>后台模式>远程通知
• 处理 didReceiveRemoteNotification
