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，我按照这样设置Push有效负载：

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

我接受推送，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问题相同（确保您的问题不是由于Parse）。只需在此处发布我的解决方案，以防其他任何人遇到同样的问题。

我的问题出在通知类别中。

确保在注册通知设置时设置了类别（我使用的是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，请确保有效负载中有“类别”，其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"
}

如果有人在使用 Firebase远程通知时遇到此问题，则会出现这种情况。

请让后端开发人员发送：

"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。

看看我的样本：

   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()

这对我来说可以获得在Swift中使用Parse显示和工作的交互式推送通知。请注意，您需要为要创建的每个交互式按钮创建UIMutableNotificationAction。下面的内容详细介绍了配置按钮选项的详细信息。

在您的app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
}

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

在您注册UINotificationSettings之前，您似乎没有设置类别或至少没有设置类别 - 您需要先设置它们，否则它将无法正常工作。

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。希望这会有所帮助：
