Question

成功保存后，我无法让我的JPEG图像显示在Parse上。这是我的代码：

BOOL

代码运行并且所有内容都正确存储在Parse中，除了图像仍然是“未定义”，但我的print语句返回：

var createPost = PFObject(className: "Loading_Post") createPost["userObjectId"] = PFUser.currentUser()?.objectId let imageOne = image1.image as UIImage! let imageData1 = UIImageJPEGRepresentation(imageOne, 0.5) let imageFile1 = PFFile(name: "image1.jpg", data: imageData1!) print(imageFile1) createPost["image1"] = imageFile1 createPost.saveInBackgroundWithBlock { (success, error) -> Void in if error == nil { self.displayAlert("success! ", message: "Your Post has been saved successfully") } else { self.displayAlert("Could not post image", message: "Please try again later") } }

谢谢！

您可能需要首先保存PFFile图像，然后将其保存到PFObject。试试这个，

imageFile1.saveInBackgroundWithBlock { (success, error) -> Void in

  if error == nil {

     var createPost = PFObject(className: "Loading_Post")

     createPost["userObjectId"] = PFUser.currentUser()?.objectId

     createPost["image1"] = imageFile1

     createPost.saveInBackgroundWithBlock { (success, error) -> Void in

        if error == nil {

            self.displayAlert("success! ", message: "Your Post has been saved successfully")

        } else {

            self.displayAlert("Could not post image", message: "Please try again later")
        }

  } else {

     self.displayAlert("Could not post image", message: "Please try again later")
  }

尝试保存解析时，这是一个简单的拼写错误。＆＃34;图像1＆＃34;应该是＆＃34; Image1＆＃34;。很抱歉没有抓住这个！
