I am downloading a JPEG image from a server and assigning it to an image object in my iPhone app using an NSURLConnection.
All works fine when I’m on a Wifi connection, but as soon as I switch to 3G, the quality of the JPEG downloaded reduces dramatically.
Has anyone else experienced this?
Does anyone know of a way to force the iPhone to download the full quality JPEG?
Thanks in advance! Nick.
If it’s the 3G provider that compresses data on the fly I don’t think you can do anything about it. Download the image with Safari via 3G -> if the image looks bad (and I expect it will) then it’s the provider that compresses it.
To workaround this problem zip the image on the server and unzip it in the application -> this should bypass the compression on the 3G side.
