1) On iOS < 5.0 implement following method in your delegate:

Sent as the body (message data) of a request is transmitted (such as in an http POST request). (Available in iOS 3.0 through iOS 4.3.)

- (void)connection:(NSURLConnection *)connection didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite

2) In iOS >= 5.0

No documentation available

[NSURLConnectionDataDelegate connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:]
