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人员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.我希望能够从服务器远程发送通知.我该怎么办?

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

虽然给出了很好的答案来处理推送通知，但我仍然相信可以立即共享完整的完整案例以简化操作:

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

要注册APNS的应用程序，(将以下代码包含在AppDelegate.swift中的didFinishLaunchingWithOptions方法中)

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申请

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)

}

在收到通知后，以下代表将呼叫:

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()
            }
}

要确定授予的权限，我们可以使用:

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")
        }
    }

因此，APNS的清单:

So the checklist of APNS:

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

注意: ，如果在SSL证书后创建配置文件，那会很好.

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

使用代码:

With Code:

• 注册用于推送通知的应用
• 处理didRegisterForRemoteNotificationsWithDeviceToken方法
• 设置目标>功能>后台模式>远程通知
• 处理didReceiveRemoteNotification
