Swift - 解析查詢whereKey包含

我有一個解析對象，我已經保存到LDS，我想通過1鍵和另一個鍵下的條目進行搜索。Swift - 解析查詢whereKey包含

關鍵：這很好。

checkQuery.whereKeyExists("File-rZVgZNpNuB")

包含的鍵：這不起作用。

checkQuery.whereKey("seachKey", contains: "myItem0000000000")

該控制檯是打印：

-[__NSArrayM length]: unrecognized selector sent to instance 0x7c09bbb0

我猜因爲mySearchString是它返回一個NSMutable陣列的「searchKey」字段內的對象。它很容易從數組中獲取數據，一旦我有對象，但我需要在「searchKey」字段中搜索此字符串以查找對象。由於各種原因，我不能用「myItem0000000000」鍵來保存對象。也許我可以添加它作爲第三個關鍵，當我保存對象，但似乎有點混亂。

它在那裏，如果我通過SQL Lite查看對象，我可以看到它。

{"className":"downloadedAudio","__complete":true,"__operations":[{"ACL":{"*":{"read":true},"rZVgZNpNuB":{"write":true,"read":true}},"File-rZVgZNpNuB":{"__op":"Add","objects":[{"url":"https:\/\/parse-server-nextbreath-s3-bucket.s3.amazonaws.com\/b5d2110dce0b50dc3a1c620731fad66e_The%20Name%20of%20the%20Wind%2024-92.mp3","name":"b5d2110dce0b50dc3a1c620731fad66e_The Name of the Wind 24-92.mp3","__type":"File"}]},"__uuid":"77AE38AF-1ADB-4795-9BB0-5A5AB7205E28","__updatedAt":{"iso":"2017-03-03T21:28:19.637Z","__type":"Date"},"searchKey":{"__op":"Add","objects":["myItem0000000000"]}}],"isDeletingEventually":0}

---- ----編輯搜索：

 let searchKey = "File-\(PFUser.current()!.objectId!)" 
     let checkQuery = PFQuery(className: "downloadedAudio") 
     checkQuery.whereKeyExists(searchKey) 
     //checkQuery.whereKeyExists(item.name) 
     //checkQuery.whereKey("seachKey", contains: item.name) 
     checkQuery.fromLocalDatastore() 
     checkQuery.getFirstObjectInBackground(block: { (object, error) in 
      if object != nil { 
       // object?.unpinInBackground() 
       object?.unpinInBackground(block: { (success, error) in 
        if success {

節省：

let query = PFQuery(className: "Part") 
query.whereKey("objectId", equalTo: selectedObjectId) 
query.getFirstObjectInBackground { (object, error) in 
    if error != nil || object == nil { 
     // ---- 
    } else { 

     let searchKey = "File-\(PFUser.current()!.objectId!)" 
     downloadedAudio.add(object?.object(forKey: "partAudio") as! PFFile, forKey: file) 
     downloadedAudio.add(object?.object(forKey: "partName") as! String, forKey: searchKey) 
     let downloadedFile = object?.object(forKey: "partAudio") as! PFFile 
     downloadedFile.getDataInBackground({ (data, error) in

searchKey字段是否爲解析服務器中的數組類型？你的最後一行有一些額外的東西...共享你的整個快速解析下載代碼，它打印什麼錯誤...在我的項目中，它的工作很棒... –

我相信你得到的是錯誤，因爲"File-rZVgZNpNuB"是無效鍵。請記住，密鑰只能以小寫字母開頭。
