ios - 使用 Swift 解析推送时没有声音

Question

我在 Xcode 7.1 iOS 9.1 中使用 swift，我最近注意到当我从 parse.com 或客户端(在我的应用程序中)发送推送通知时，我的 AppDelegate 没有发出任何声音:

import UIKit
import CoreData

let kREACHABLEWITHWIFI = "ReachableWithWIFI"
let kNOTREACHABLE = "NotReachable"
let kREACHABLEWITHWWAN = "ReachableWithWWAN"

var reachability: Reachability?
var reachabilityStatus = kREACHABLEWITHWIFI

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
var internetReach: Reachability?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    Parse.setApplicationId("A30cE46XOKXwA0EaGVKzEvQ2dmt1TZQo0DaykiRb", clientKey: "isuJsPBVcHFSBSTmTCnWOG6os0RzTME2QCQEHvP3")

    //Setup Push Notifications



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

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

    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)

    //Setup Push Notifications

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "reachabilityChanged:", name: kReachabilityChangedNotification, object: nil)

    internetReach = Reachability.reachabilityForInternetConnection()
    internetReach?.startNotifier()

    if (internetReach != nil) {

        self.statusChangedWithReachability(internetReach!)

    }




    return true
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {

    UIApplication.sharedApplication().registerForRemoteNotifications()

}

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

    let currentInstallation:PFInstallation = PFInstallation.currentInstallation()
    currentInstallation.setDeviceTokenFromData(deviceToken)
    currentInstallation.save()

}

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

    print(error.localizedDescription)

}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    PFPush.handlePush(userInfo)

}

func reachabilityChanged(notification: NSNotification){

    print("Reachability Status Changed...")
    reachability = notification.object as? Reachability
    self.statusChangedWithReachability(reachability!)

}

func statusChangedWithReachability(currentReachabilityStaus: Reachability){

    var networkStatus: NetworkStatus = currentReachabilityStaus.currentReachabilityStatus()
    var statusString: String = ""

    print("Status Value: \(networkStatus.rawValue)")

    if(networkStatus.rawValue == NotReachable.rawValue){

        print("Network Not Reachable...")
        reachabilityStatus = kNOTREACHABLE

    }

    else if(networkStatus.rawValue == ReachableViaWiFi.rawValue){

        print("Network Reachable via WIFI")
        reachabilityStatus = kREACHABLEWITHWIFI

    }

    else if(networkStatus.rawValue == ReachableViaWWAN.rawValue){

        print("Network Reachable via Provider")
        reachabilityStatus = kREACHABLEWITHWWAN

    }

    NSNotificationCenter.defaultCenter().postNotificationName("NetworkStatusChanged", object: nil)


}

func applicationWillResignActive(application: UIApplication) {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

func applicationDidEnterBackground(application: UIApplication) {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

func applicationWillEnterForeground(application: UIApplication) {
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

func applicationDidBecomeActive(application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

func applicationWillTerminate(application: UIApplication) {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    // Saves changes in the application's managed object context before the application terminates.





    NSNotificationCenter.defaultCenter().removeObserver(self, name: kReachabilityChangedNotification, object: nil)

    //self.saveContext()
}

        coordinator = nil
        // Report any error we got.
        let dict = NSMutableDictionary()
        dict[NSLocalizedDescriptionKey] = "Failed to initialize the application's saved data"
        dict[NSLocalizedFailureReasonErrorKey] = failureReason

    }
    }

    catch let error as NSError {
        print(error)
    }

    return coordinator
}()

这里还有一些我试图发送客户端通知的代码:

@IBAction func sendPush(sender: UIBarButtonItem) {

    let data = [

        "sounds" : "72128__kizilsungur__sweetalertsound4-2.wav"

    ]

    do{

    let push = PFPush()
    push.setChannel("Members")
    push.setData(data)
    push.setMessage(notificationTextField.text)
    try push.sendPush()

    }catch{
        print(error)
    }

}

任何有关如何解决此问题的帮助都会很棒!

Answer 1

假设 72128__kizilsungur__sweetalertsound4-2.wav 被正确地作为 Assets 包含在您的项目中，这似乎是一个简单的拼写错误。将 "sounds": ... 更改为 "sound": ...

let data = [

    "sounds" : "72128__kizilsungur__sweetalertsound4-2.wav"

]

应该是

let data = [

    "sound" : "72128__kizilsungur__sweetalertsound4-2.wav"

]
