ios - 未调用handleWatchKitExtensionRequest 的问题？

Question

我正在尝试更新我的 watch 套件应用程序以添加一些从 JSON 文件解析的数据。我正在结合从 Parse 获取一些数据来执行此操作。

我收到错误:

The UIApplicationDelegate in the iPhone App never called reply() in -[UIApplicationDelegate application:handleWatchKitExtensionRequest:reply:]

我尝试调试 handleWatchKitExtensionRequest 但它没有崩溃，并且由于某种原因我添加的 println 从未打印。

这是我的代码:

func application(application: UIApplication, handleWatchKitExtensionRequest userInfo: [NSObject : AnyObject]?, reply: (([NSObject : AnyObject]!) -> Void)!) {
    var favouritesArrayDefaults: NSMutableArray! = [""]

    println("1")
    var keyStore = NSUbiquitousKeyValueStore()
    if keyStore.arrayForKey("FavouritesList") != nil {
        let tempFavourites: NSArray = keyStore.arrayForKey("FavouritesList")!
        favouritesArray = tempFavourites.mutableCopy() as! NSMutableArray
    } else {
        println("3")
    }

    println(favouritesArrayDefaults)

    if let pfqueryRequest: AnyObject = (userInfo as? [String: AnyObject])?["parkName"] {
        println("HELLO")

        let taskID = beginBackgroundUpdateTask()
        //Must start and end task to allow time for query to complete

        var name = ""
        var waitTime = ""
        var hasWaitTime = false
        var fastPass = false
        var heightRestriction = false
        var singleRider = false
        var disabledAccess = false
        var mustSee = false
        var fastPassTime = ""

        var namesArray: [String] = []
        var waitTimesArray: [String] = []
        var favouritesArray: [String] = []
        var hasWaitTimeArray: [Bool] = []
        var fastPassArray: [Bool] = []
        var heightRestrictionArray: [Bool] = []
        var singleRiderArray: [Bool] = []
        var disabledAccessArray: [Bool] = []
        var mustSeeArray: [Bool] = []
        var fastPassTimeArray: [String] = []

        var query = PFQuery(className: pfqueryRequest as! String)
        query.orderByAscending("Name")
        var objects = query.findObjects()

        if let objects = objects as? [PFObject] {
            for object in objects {
                name = (object.objectForKey("Name") as? String)!
                waitTime = (object.objectForKey("WaitTime") as? String)!
                hasWaitTime = (object.objectForKey("HasWaitTime") as? Bool)!
                fastPass = (object.objectForKey("FastPass") as? Bool)!
                heightRestriction = (object.objectForKey("HeightRestriction") as? Bool)!
                singleRider = (object.objectForKey("SingleRider") as? Bool)!
                disabledAccess = (object.objectForKey("DisabledAccess") as? Bool)!
                mustSee = (object.objectForKey("MustSee") as? Bool)!

                namesArray.append(name)
                waitTimesArray.append(waitTime)
                hasWaitTimeArray.append(hasWaitTime)
                fastPassArray.append(fastPass)

            }

            var urlString = (DataManager.sharedInstance.getParkByName(pfqueryRequest as! String)?.dataSource)!

            if let url = NSURL(string: urlString) {
                if let data = NSData(contentsOfURL: url, options: .allZeros, error: nil) {
                    let json = JSON(data: data)

                    for count in 0...json.count - 1 {
                        let rideName: JSON = json[count]["name"]
                        let waitTime: JSON = json[count]["waitTime"]
                        var fastPassTime: JSON = json[count]["fastPass"]

                        if find(namesArray, rideName.string!) != nil {
                            let index = find(namesArray, rideName.string!)

                            var modifiedWaitTime = "".join(waitTime.string!.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet))

                            if waitTime == "Down" || waitTime == "Closed" {
                                modifiedWaitTime = "Closed"
                            }

                            if fastPassTime.string == nil {
                                fastPassTime = "Unavailable"
                            } else if fastPassTime.string == "N/A" {
                                fastPassTime = "Expired"
                            }

                            waitTimesArray.removeAtIndex(index!)
                            waitTimesArray.insert(waitTime.string!, atIndex: index!)

                            fastPassTimeArray.removeAtIndex(index!)
                            fastPassTimeArray.insert(fastPassTime.string!, atIndex: index!)
                        }
                    }
                }
            }

            for favourite in favouritesArrayDefaults {
                favouritesArray.append(favourite as! String)
            }

            println(fastPassTimeArray)
            reply(["success": true, "name": namesArray, "waitTime": waitTimesArray, "hasWaitTime": hasWaitTimeArray, "favourites": favouritesArray, "fastPass": fastPassArray, "heightRestriction": heightRestrictionArray, "singleRider": singleRiderArray, "disabledAccess": disabledAccessArray, "mustSee": mustSeeArray, "fastPassTime": fastPassTimeArray])

            endBackgroundUpdateTask(taskID)
        }
    } else if let pfqueryRequest: AnyObject = (userInfo as? [String: AnyObject])?["parkNameSubmit"] {
        let taskID = beginBackgroundUpdateTask()

        var query = PFQuery(className: pfqueryRequest as! String)
        //query.orderByAscending("Name")
        query.whereKey("Name", equalTo: userInfo!["name"]!)
        query.getFirstObjectInBackgroundWithBlock {
            (object: PFObject?, error: NSError?) -> Void in
            if error != nil {
                println("The getFirstObject request failed.")
            } else {
                if let obj = object {
                    obj.setValue(userInfo!["waitTime"], forKey: "WaitTime")
                    obj.saveInBackground()
                }
                println("Successfully retrieved the object.")
            }
        }

        reply(["success": true, "message": "Hello!"])

        endBackgroundUpdateTask(taskID)
    }
}

对于大量的代码，我深表歉意，但我真的不知道问题出在哪里。

大家有什么想法吗？

将您的 reply() 调用放入“不相关代码”部分。问题是在任何情况下都应该调用 reply() 处理程序，但在您的示例中，如果 pfqueryRequest 为 nil 处理程序永远不会被调用已调用。
