Question

我正在尝试使用Parse推送通知在我的应用上运行（所有swift）但在尝试实现时，我收到错误'PFInstallation' does not have a member named 'saveInBackground'

这是我的代码。

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更改为currentInstallation.saveEvenutally()时，代码编译得很好..

但是在尝试成功注册推送通知时，控制台中会弹出一个错误Error: deviceType must be specified in this operation (Code: 135, Version: 1.4.2)

我花了好几个小时试图解决这个问题，没有骰子，任何帮助都是值得欣赏的。

Answer 1

对于出现此错误的任何其他人，请确保将Bolts框架导入您的桥接头文件

在他们的废话文档中没有概述。

这解决了这个问题。

以下是代码。

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

只需将其添加到您的桥接标题即可。感谢

Answer 2

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。（source）

所以而不是：

var currentInstallation: PFInstallation = PFInstallation()

尝试：

var currentInstallation = PFInstallation.currentInstallation()

Answer 3

只需在AppDelegate.swift文件中写import Bolts

除了导入Bolts之外，我还通过将功能更改为
