问题 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?
