I'm implementing a Facebook video upload using the new Social APIs for iOS 6, everything is working fine, except that I didn't find a way to know how the upload is progressing... the only API that Apple seems to provide is that if the upload is completed or if it failed, it's possible that they are so ------- that they don't provide a method to know it?
I also didn't find ANY question regarding this topic, it's not possible that I'm the only one interested in it, if someone knows anything else, let us know.
Use preparedURLRequest to get the NSURLRequest object. Sending the request by hand with NSURLConnection lets you provide a delegate that can handle delegate methods like, say, connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:.
