由于某些奇怪的原因，我的图像已停止保存以进行解析。之前，我的代码运行良好，我根本没有对其进行任何更改。

这是我的代码:

 var posts = PFObject(className: "Product")
            posts["shortDescription"] = productShortDescription
            posts["user"] = PFUser.currentUser()
            posts["longDescription"] = productLongDescription
            posts["title"] = productTitle
            posts["price"] = productPrice
            posts.saveInBackgroundWithBlock({
                (success: Bool, error: NSError?) -> Void in

                if error == nil {
                    //success saving, now save image

                    //create image data

                    var imageData = UIImagePNGRepresentation(self.newItemImageView.image)


                    //create parse file

                    var parseImageFile = PFFile(name: "upload_image.png", data: imageData)
                    posts["imagePNG"] = parseImageFile
                    posts.saveInBackgroundWithBlock({
                        (success: Bool, error: NSError?) -> Void in

                        if error == nil {
                            // take user home
                            println("data uploaded")
                            self.performSegueWithIdentifier("returnHomeAfterUpload", sender: self)
                        }else {
                            println(error)

                        }


                    })

                }else {

                    println(error)
                }

            })

其他一切都保存完好，但我的图像数据有什么问题？ 谢谢!

最佳答案

在你的代码中，你没有保存 parseImageFile，所以首先 parseImageFile.SaveInBackground 成功后将其设置为 posts 然后保存 帖子以及

应该是这样的

         var posts = PFObject(className: "Product")
                posts["shortDescription"] = productShortDescription
                posts["user"] = PFUser.currentUser()
                posts["longDescription"] = productLongDescription
                posts["title"] = productTitle
                posts["price"] = productPrice
                posts.saveInBackgroundWithBlock({
                    (success: Bool, error: NSError?) -> Void in

                    if error == nil {
                        //success saving, now save image
                        //create image data
                        var imageData = UIImagePNGRepresentation(self.newItemImageView.image)                            
                        //create parse file
                        var parseImageFile = PFFile(name: "upload_image.png", data: imageData)
parseImageFile.saveInBackgroundWithBlock({
posts["imagePNG"] = parseImageFile
                        posts.saveInBackgroundWithBlock({
                            (success: Bool, error: NSError?) -> Void in

                            if error == nil {
                                // take user home
                                println("data uploaded")
                                self.performSegueWithIdentifier("returnHomeAfterUpload", sender: self)
                            }else {
                                println(error)

                            }


                        })
})


                    }else {

                        println(error)
                    }

                })

我没有在编辑器上测试这段代码，你可能会发现一些语法错误，但它应该是这样的......

事情是当你创建 parseImageFile 然后 saveInBackground 和内部 block 设置它发布然后再次保存发布
