How to save images to Parse? - ios

Question

For some odd reason, my images have stopped saving to parse. Before, my code worked fine and I have not made any changes to it at all.
Here is my code:
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)
}
})
Everything else is stored perfectly, but what's the issue with my image data?
Thanks!

In your code you are not saving parseImageFile, so first parseImageFile.SaveInBackground and on success set it to posts and then save posts as well
Should be something like this
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)
}
})
I haven't test this code on editor you may find some syntax error, but it should be something like this...
so things is when you create parseImageFile and then saveInBackground and inside block set it posts and then save post again

I've checked your code and it's works fine.
let image = UIImage(named: "img.jpg")
let data = UIImagePNGRepresentation(image)
let file = PFFile(name: "img", data: data)
let parseObj = PFObject(className: "testClass")
parseObj["text"] = "hello"
parseObj["image"] = file
parseObj.saveInBackgroundWithBlock { (_, _) -> Void in }
Try this, if this code will be works - easiest way for you is remove "Product" table and create it again.
