如何在Swift中设置推送通知
我正在尝试为我的应用程序设置推送通知系统。我有服务器和开发人员许可证来设置推送通知服务。
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。我怎样才能做到这一点?
回答:
尽管可以很好地处理推送通知,但我仍然相信可以立即共享完整的完整案例以简化操作:
要注册APNS的应用程序,(在AppDelegate.swift中的didFinishLaunchingWithOptions方法中包含以下代码)
var settings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes:UIUserNotificationType.Alert|UIUserNotificationType.Sound, categories: nil)UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
引入了UserNotifications框架:
导入UserNotifications框架,并在AppDelegate.swift中添加UNUserNotificationCenterDelegate
注册APNS的申请
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,以下代表将致电:
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()
}
}
要确定给定的许可,我们可以使用:
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")
}
}
- 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Provisioning配置文件,并确保在添加沙箱的情况下添加设备(开发Provisioning)
如果在SSL证书后创建配置文件,那会很好。
- 注册应用程序以进行推送通知
- 处理didRegisterForRemoteNotificationsWithDeviceToken方法
- 设置目标>功能>后台模式>远程通知
- 处理didReceiveRemoteNotification
