无法在 iOS8 上设置交互式推送通知

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：

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 负载设置为如下：

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

我收到了推送，但不是使用我设置的自定义按钮。

我不确定我的问题是否与您的问题相同（确保您的问题不是由于 Parse 引起的）。只要在这里发布我的解决方案，以防其他人遇到同样的问题。

我的问题出在通知类别中。

确保您在注册通知设置时设置了类别（我使用的是 Objective-C，没有太大区别）：

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，请确保有效负载中有“类别”，并且该值与您在客户端中定义的值相同。就我而言，它是这样的：

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