解析推送通知-快速安装不起作用

Question

我正在尝试让Parse通知在我的应用程序上工作(都是快速的)，但是在尝试实现时，我得到了错误'PFInstallation' does not have a member named 'saveInBackground'。

这是我的密码。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    Parse.setApplicationId("APP ID HIDDEN", clientKey: "CLIENT ID HIDDEN")

   // let notificationTypes:UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
    //let notificationSettings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    var notificationType: UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound

    var settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationType, categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    UIApplication.sharedApplication().registerForRemoteNotifications()

    //UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
    // Override point for customization after application launch.
    return true
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings!) {
   UIApplication.sharedApplication().registerForRemoteNotifications()

}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

    var currentInstallation: PFInstallation = PFInstallation()
    currentInstallation.setDeviceTokenFromData(deviceToken)
    currentInstallation.saveInBackground()

    println("got device id! \(deviceToken)")

}


func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    println(error.localizedDescription)
    println("could not register: \(error)")
}

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

当我将currentInstallation.saveInBackground改为currentInstallation.saveEvenutally()时，代码编译得很好。

但是，当尝试成功地注册推送通知时，控制台中会弹出一个错误，上面写着Error: deviceType must be specified in this operation (Code: 135, Version: 1.4.2)。

我花了好几个小时试图弄清楚，没有骰子，任何帮助都是感激的。

对于其他有此错误的人，请确保将Bolts框架导入桥接头文件中。

在他们的垃圾文件里没有提到。

这就解决了问题。

下面是密码。

#import <Parse/Parse.h>
#import <Bolts/Bolts.h>

只要把这个加到你的桥接头上，你就可以走了。谢谢

有效的PFInstallation只能通过PFInstallation currentInstallation实例化，因为所需的标识符字段是只读的。(来源)

因此，与其：

var currentInstallation: PFInstallation = PFInstallation()

尝试：

var currentInstallation = PFInstallation.currentInstallation()

只需在您的import Bolts文件中写入AppDelegate.swift
