Image within PFFile will be uploaded to parse inst

Question

I am using swift with the Parse Framework (1.6.2). I am storing data into the local datastorage. The data consists of a few strings and an image. This image will be stored within a PfFile and then will be added to the PfObject.

Now I wondered why the image doesn't get saved until I noticed I needed to call the save() method of the PFFile. Problem is that the Image then seems to be uploaded to Parse which I don't want. I want it to be stored on the local device..

Is there a solution for this?

Thanks

Edit:

The code works like this:

var spot = PFObject(className: "Spot")
let imageData = UIImageJPEGRepresentation(spotModel.getPhoto(), 0.05)
let imageFile = PFFile(name:"image.jpg", data:imageData)

spotObj.setObject(spotModel.getCategory(), forKey: "category")
spotObj.setObject(imageFile, forKey: "photo")


//if I simply would do this, the PFObject will be saved into the local datastorage, but the image won't be saved
spotObj.pin()

//if I do this, the image will be saved also BUT it won't be saved into the local data storage but will be uploaded to parse
imageFile.save()
spotObj.pin()

Okay, take a look here Save eventually on PFObject with PFFile (Parse Local Datastore)?. One this is for sure, if you call save on PFFile it will get save to online datastore. So you should use PFFile.save(). I think best option for you is to save the file in some folder. locally and save that path in PFObject. Parse documentation just say this

"Pinning a PFObject is recursive, just like saving, so any objects that are pointed to by the one you are pinning will also be pinned. When an object is pinned, every time you update it by fetching or saving new data, the copy in the local datastore will be updated automatically. You don't need to worry about it at all."

It recursively calls .pin() on the other objects in your main PFObject. But if you take a look at PFFile API doc it doest have a .pin() which means it doesn't support saving PFFile to local datastore. So I would say you should save them in some directory and save path in your PFObject.

Update

save:

Saves the file synchronously and sets an error if it occurs.

- (BOOL)save:(NSError **)error
Parameters
error
Pointer to an NSError that will be set if necessary.

Return Value
Returns whether the save succeeded.
