Hi Rick, You can implement the following NSURLSessionTaskDelegate method in order to receive progress updates about the upload task while your app is running:
- (void)URLSession:(NSURLSession <https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLSession_class/index.html#//apple_ref/doc/c_ref/NSURLSession> *)session task:(NSURLSessionTask <https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLSessionTask_class/index.html#//apple_ref/doc/c_ref/NSURLSessionTask> *)task didSendBodyData:(int64_t)bytesSent totalBytesSent:(int64_t)totalBytesSent totalBytesExpectedToSend:(int64_t)totalBytesExpectedToSend https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLSessionTaskDelegate_protocol/index.html#//apple_ref/occ/intfm/NSURLSessionTaskDelegate/URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend: You can also poll for progress at any times via the countOfBytesSent and countOfBytesExpectedToSend properties on NSURLSessionTask. There are equivalent properties / delegate methods for download tasks as well.
