swift - 看不到我在 Parse 中发布的消息

Question

我正在创建一个 yik yak 克隆，但我似乎看不到我在 Parse 上的 textField(string) 中发布的消息。我的代码中是否有什么错误导致它没有显示在 Parse 上？

  @IBAction func postPressed(sender: AnyObject) {


    if(currLocation != nil){
        let testObj = PFObject(className: "BubbleTest")

        testObj["userName"] = PFUser.currentUser()?.username
        //testObj["profileName"] = PFUser.valueForKey("profileName") as! String
        //testObj["photo"] = PFUser.currentUser()?.valueForKey("photo") as! PFFile
        testObj["textField"] = self.textField.text
        testObj["location"] = PFGeoPoint(latitude: currLocation!.latitude , longitude: currLocation!.longitude)
        testObj["count"] = 0
        testObj["replies"] = 0
        testObj.saveInBackground()


        self.dismissViewControllerAnimated(true, completion: nil)
    }
    else {
        alert()
    }

您看不到任何内容的原因是您将其发布到错误的类中。根据图片BubbleTest是类名而不是YikYakTest

替换此行

   let testObj = PFObject(className: "YikYakTest")

由

let testObj = PFObject(className: "BubbleTest")

您的代码应如下所示:

注意使用 saveInBackgroundWithBlock 方法，以便您可以检查保存时是否有错误

 let testObj = PFObject(className: "BubbleTest")
    let username = PFUser.currentUser()?.username
    testObj["userName"] = username
    testObj["textField"] = self.textField.text
    testObj["Location"] = PFGeoPoint(latitude:currLocation.latitude , longitude: currLocation.longitude)
    testObj["count"] = 0
    testObj["replies"] = 0
    testObj.saveInBackgroundWithBlock { (success:Bool, error :NSError?) -> Void in
        if error == nil
        {
           print("detail is saved")
           self.dismissViewControllerAnimated(true, completion: nil)
        }
        else
          {
              print("error")
          }
    }

当您保存PFGeopoint坐标时，将其保存到Location列而不是location
