Firebase Storage store metadata url in realtime database and use it asynchronous download image and cache it

[Saran]

Hi, 

I am using IOS SDWebimage library to asynchronous download image and cache it. I would like to know if below method is the right way to do it.

    func storeUserPic(uid: String, data: NSData)

    {

        let filePath = REF_STORAGE.child(“user/test.jpeg")

        let metaData = FIRStorageMetadata()

        metaData.contentType = "image/jpeg"

        

        filePath.putData(data, metadata: metaData) { (meta, error) in

            if let error = error

            {

                print(error.localizedDescription)

                return

            }

            else

            {

                self.REF_USERS.child(uid).updateChildValues([“testpic” : meta!.downloadURLs![0].absoluteString])

            }

        }

        

    }

Now when i refer to the user uid i will be able to use the URL and hence SDWebimage to display it.

Saran,

This would be one way of storing the download URL (in the database) and making it accessible to SDWebImage for download. We're working on an extension to SDWebImage to allow Firebase Storage references to be "downloaded" directly in SDWebImage, which would potentially eliminate the need for you to store a public download URL at all :)

Thanks,
