Question

嘿伙计们我对Parse中的一个内容有很多意见。我想得到关于一条评论的输入数量。与计算喜欢类似。我怎么能这样做？

let guessstat:PFObject = PFObject(className: "Guesscontent")
var guessData:NSMutableArray = NSMutableArray()
func loadData(){

    guessData.removeAllObjects()

    let findTimeLineData:PFQuery = PFQuery(className: "Guesses")

    findTimeLineData.whereKey("content", equalTo: self.guessTextView.text)
    findTimeLineData.findObjectsInBackgroundWithBlock{

        (objects: [PFObject]?, error: NSError?) -> Void in

        if error == nil{
            if let objects = objects {
                for object in objects{

                    self.guessData.addObject(object)

                }
            }
            let array:NSArray = self.guessData.reverseObjectEnumerator().allObjects
            self.guessData = NSMutableArray(array: array)


        }

    }
    guessstat["sell"] = guessData.count

}

Answer 1

您应用中的每个输入都对应一个评论。您是否在实际猜测和猜测内容之间建立了关系？

首先，您可能需要在两个类之间建立关系......

var Guesscontent = PFObject(className:"GuessContent")

var Guesses = PFObject(className:"Guesses")

//Create the relationship
Guesses["parent"] = GuessContent

//Everytime a user has made a guess, save it
Guesses.saveInBackground()

然后尝试你正在做的事情......让我知道，我无法发表评论

嘿伙计们我找到了解决方案

让query = PFQuery（className：“Guesses”）

    query.whereKey("content", equalTo:self.guessTextView.text)
    query.countObjectsInBackgroundWithBlock {

    (count: Int32, error: NSError?) -> Void in
        if error == nil

        {
        self.stattlabelsell.text = "\(count)"
        }
    }
