如何设置Parse客户端侧推通知

Question

我正在尝试使用Parse在测试项目上设置推送通知。

我已按照推送设置教程/指南进行操作。

我已在Parse仪表板中启用客户端推送。

我已更新.plist

我已在目标和项目的构建设置中设置了代码签名设置。

我发送推文：

PFPush.sendPushMessageToChannelInBackground("global", withMessage: "First push ever") { (success: Bool!, error: NSError!) -> Void in
 ...
}

当我尝试发送推送时，我收到以下错误

Error Domain=Parse Code=115 "The operation couldn’t be completed. (Parse error 115.)" UserInfo=0x1764cad0 {code=115, error=Client-initiated push isn't enabled.}

这

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError)

我是否错误地设置了配置文件和证书？有没有办法检查这个？我是否在appDelegate中错误地设置了Parse？有没有办法检查这个？

我的应用代表看起来像这样：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
 Parse.setApplicationId("xxx", clientKey: "xxx")
 var userNotificationTypes = (UIUserNotificationType.Alert | UIUserNotificationType.Badge)
 var settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
 application.registerUserNotificationSettings(settings)
 application.registerForRemoteNotifications()
 return true
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
 var currentInstallation = PFInstallation.currentInstallation()
 currentInstallation.setDeviceTokenFromData(deviceToken)
 currentInstallation.channels = ["global"]
 currentInstallation.save()
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
 if error != nil {
  println(error)
 }
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
 PFPush.handlePush(userInfo)
}

func applicationDidBecomeActive(application: UIApplication) {
 var currentInstallation = PFInstallation.currentInstallation()
 if currentInstallation.badge != 0 {
 currentInstallation.badge = 0
 currentInstallation.saveEventually()
 }

您不会从应用代理发送客户推送。您从触发推送的操作发送它们。

这是Objective C中的一个例子：

// Create our Installation query
PFQuery *pushQuery = [PFInstallation query];
[pushQuery whereKey:@"channels" equalTo:@"Giants"]; // Set channel
[pushQuery whereKey:@"scores" equalTo:YES];

// Send push notification to query
PFPush *push = [[PFPush alloc] init];
[push setQuery:pushQuery];
[push setMessage:@"Giants scored against the A's! It's now 2-2."];
[push sendPushInBackground];

而且，如果您计划将此应用程序发送到应用程序商店，您应该使用云代码来处理客户端推送，因为直接客户端到客户端会将您的应用程序推向安全漏洞。
