iOS Dropbox error loading thumbnails - ios

Question

I wanna get thumbnails for dropbox files that I display on a view. I know that I've to use the loadThumbnail method, but I don't get exactly how to do it.
I wrote this :
for file in dropboxMetadata.contents {
dbRestClient.loadThumbnail(file.path, ofSize: "s", intoPath: "https://api-content.dropbox.com/1/thumbnails/auto/")
}
but I get some errors like this :
error making request to /1/thumbnails/dropbox/star.jpg - (4) Error Domain=NSCocoaErrorDomain Code=4 "The operation couldn’t be completed.
Thanks for your help !

Petesh has the right idea. intoPath is the destination directory for those thumbnails.
Try this:
func createTempDirectory() -> String? {
let tempDirectoryTemplate = NSTemporaryDirectory().stringByAppendingPathComponent("XXXXX")
let fileManager = NSFileManager.defaultManager()
var err: NSErrorPointer = nil
// remove any previous temporary folder that's there, in case it's there
fileManager.removeItemAtPath(tempDirectoryTemplate)
if fileManager.createDirectoryAtPath(tempDirectoryTemplate, withIntermediateDirectories: true, attributes: nil, error: err) {
return tempDirectoryTemplate
} else {
print("can't create temporary directory at \(tempDirectoryTemplate)")
return nil
}
}
The above code for which I found in this question
Then you could change your own code to do something like:
let temporaryDirectory = createTempDirectory()
for file in dropboxMetadata.contents {
dbRestClient.loadThumbnail(file.path, ofSize: "s", intoPath: temporaryDirectory)
}
If this works, then you could change the "intoPath" parameter into any directory you think is more appropriate.
