将 Parse 推送通知集成到 Xcode 7 项目 (Swift)

Question

我正在将 Parse 推送通知集成到一个应用程序中，并且已经陷入 Swift 2.0 转换。代码是：

if application.respondsToSelector("registerUserNotificationSettings:") {
            let userNotificationTypes: UIUserNotificationType = [.Alert, .Badge, .Sound]
            let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
            application.registerUserNotificationSettings(settings)
            application.registerForRemoteNotifications()
        } else {
            let types: UIUserNotificationType = [.Badge, .Alert, .Sound]
            application.registerForRemoteNotificationTypes(types)
        }

Xcode 抱怨“无法将类型 'UIUserNotificationType' 的值转换为预期的参数类型 'UIRemoteNotificationType'

Answer 1

尝试下面的代码，尽管 Xcode 仍然显示 UIRemoteNotificationType 在 iOS 8.0

中被弃用的警告

let types : UIRemoteNotificationType = [.Badge, .Alert, .Sound]
application.registerForRemoteNotificationTypes(types)

Answer 2

尝试以下代码，因为 UIRemoteNotification 已弃用，请使用 registerUserNotificationSettigns 设置通知设置。但是记得在apple的会员中心和parse处配置push notifications才能正常工作。您可以从第 1 步到第 4 步按照本教程进行操作，这很棒。 https://www.parse.com/tutorials/ios-push-notifications

if application.respondsToSelector("registerUserNotificationSettings:") {
   let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
   application.registerUserNotificationSettings(settings)
   application.registerForRemoteNotifications()
}

Answer 3

试试这个代码...

应用delegate.swift

import UIKit
import Parse

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

//--------------------------------------
// MARK: - UIApplicationDelegate
//--------------------------------------

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    Parse.setApplicationId("APIKEYHERE", clientKey: "CLIENTKEYHERE")

    let types:UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
    let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)

    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

    return true
}

//--------------------------------------
// MARK: Push Notifications
//--------------------------------------

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let installation = PFInstallation.currentInstallation()
    installation.setDeviceTokenFromData(deviceToken)
    installation.saveInBackground()

    PFPush.subscribeToChannelInBackground("") { (succeeded: Bool, error: NSError?) in
        if succeeded {
            print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.\n");
        } else {
            print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.\n", error)
        }
    }
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    if error.code == 3010 {
        print("Push notifications are not supported in the iOS Simulator.\n")
    } else {
        print("application:didFailToRegisterForRemoteNotificationsWithError: %@\n", error)
    }
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    PFPush.handlePush(userInfo)
    if application.applicationState == UIApplicationState.Inactive {
        PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(userInfo)
    }
  }

}
