无法在 iOS8 上设置交互式推送通知

Question

我已经能够设置交互式本地通知，但远程通知不起作用。我正在使用 Parse.com 发送 JSON

我的 AppDelegate.Swift 看起来像这样：

//
//  AppDelegate.swift
//  SwifferApp
//
//  Created by Training on 29/06/14.

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
        UINavigationBar.appearance().barTintColor = UIColor.orangeColor()
        UINavigationBar.appearance().tintColor = UIColor.whiteColor()


        Parse.setApplicationId("eUEC7O4Jad0Kt3orqRouU0OJhkGuE20n4uSfrLYE", clientKey: "WypmaQ8XyqH26AeWIANttqwUjRJR4CIM55ioXvez")

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

        UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)

        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.saveInBackground()
    }

    func application(application: UIApplication!, didFailToRegisterForRemoteNotificationsWithError error: NSError!) {
        println(error.localizedDescription)
    }

    func application(application: UIApplication!, didReceiveRemoteNotification userInfo:NSDictionary!) {

        var notification:NSDictionary = userInfo.objectForKey("aps") as NSDictionary

        if notification.objectForKey("content-available"){
            if notification.objectForKey("content-available").isEqualToNumber(1){
                NSNotificationCenter.defaultCenter().postNotificationName("reloadTimeline", object: nil)
            }
        }else{
            PFPush.handlePush(userInfo)
        }
    }

    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 active 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:.
    }
}

在 Parse 上，我将 Push 负载设置如下：

{
"alert": "Tune in for the World Series, tonight at 8pm EDT",
"badge": "Increment",
"sound": "chime",
"category": "FIRST_CATEGORY"
}

我收到了推送，但没有使用我设置的自定义按钮。

Answer 1

我不确定我的问题是否与您的相同（确保您的问题不是 Parse 造成的）。只需在此处发布我的解决方案，以防其他人遇到同样的问题。

我的问题在于通知类别。

确保注册通知设置时已经设置好类别（我用的是Objective-C，差别不大）：

UIMutableUserNotificationCategory *notificationCategory = [[UIMutableUserNotificationCategory alloc] init];
            notificationCategory.identifier = @"CallNotificationCategory";
            [notificationCategory setActions:@[declineAction, answerAction] forContext:UIUserNotificationActionContextDefault];

            NSSet *categories = [[NSSet alloc] initWithObjects:notificationCategory, nil];

并且，当您发送远程通知时，请确保您在有效负载中具有“类别”，并且该值与您在客户端中定义的值相同。就我而言，它类似于：

{
  "alert": "Tune in for the World Series, tonight at 8pm EDT",
  "badge": "Increment",
  "sound": "chime",
  "category": "CallNotificationCategory"
}

这是以防万一有人在使用 Firebase 远程通知时遇到此问题。

请后台开发者发送：

"notification" : {
  "title" : YOUR_TITLE,
  "body" : YOUR_BODY,
  "click_action" : YOUR_CATEGORY_NAME
}

Answer 3

您需要在注册 APNS 时传递类别。

看看我的示例：

   var replyAction : UIMutableUserNotificationAction = UIMutableUserNotificationAction()
    replyAction.identifier = "REPLY_ACTION"
    replyAction.title = "Yes, I need!"

    replyAction.activationMode = UIUserNotificationActivationMode.Background
    replyAction.authenticationRequired = false

    var replyCategory : UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
    replyCategory.identifier = "REPLY_CATEGORY"

    let replyActions:NSArray = [replyAction]

    replyCategory.setActions(replyActions, forContext: UIUserNotificationActionContext.Default)
    replyCategory.setActions(replyActions, forContext: UIUserNotificationActionContext.Minimal)

    let categories = NSSet(object: replyCategory)



    let settings : UIUserNotificationType = UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge
    UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: settings, categories: categories))
    UIApplication.sharedApplication().registerForRemoteNotifications()

这对我来说很有效，我可以通过 Parse 在 Swift 中显示和使用交互式推送通知。请注意，您需要为要创建的每个交互按钮创建一个UIMutableNotificationAction。下面的源代码更详细地介绍了按钮的配置选项。

在您的应用委托文件中：

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

    let notificationTypes:UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound

    var notificationActionAccept :UIMutableUserNotificationAction = UIMutableUserNotificationAction()
    notificationActionAccept.identifier = "ACCEPT_IDENTIFIER"
    notificationActionAccept.title = "Accept"
    notificationActionAccept.destructive = true
    notificationActionAccept.authenticationRequired = false
    notificationActionAccept.activationMode = UIUserNotificationActivationMode.Background

    var notificationCategory:UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
    notificationCategory.identifier = "CallNotificationCategory"
    notificationCategory .setActions([notificationActionAccept], forContext: UIUserNotificationActionContext.Default)

    let notificationSettings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: NSSet(array:[notificationCategory]))
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)

    return true
}

在 Parse Cloud 中，当您发送推送时，您会将 category 匹配到 UIMutableUserNotificationCategory，就像上面提到的 @Xialin 一样。

看起来您没有设置类别，或者至少在您注册 UINotificationSettings 之后才设置它们 - 您需要先设置它们，否则它将不起作用。

我在下面的链接中获得了大部分信息。如果需要，它会更详细地介绍。希望这会有所帮助：
