Some more info. I am on Snow Leopard but get the same results on Leopard.
I took the code from NSURLConnection.SetDelegate() and moved it into my code
like this:
Action<NSURLConnection.NSURLConnectionEventDispatcher>
assignment =
(d =>
{
d.ConnectionDidCancelAuthenticationChallenge += new
NSURLConnection.ConnectionDidCancelAuthenticationChallengeEventHandler(d_ConnectionDidCancelAuthenticationChallenge);
d.ConnectionDidFailWithError += new
NSURLConnection.ConnectionDidFailWithErrorEventHandler(d_ConnectionDidFailWithError);
d.ConnectionDidFinishLoading += new
NSURLConnection.ConnectionDidFinishLoadingEventHandler(d_ConnectionDidFinishLoading);
d.ConnectionDidReceiveAuthenticationChallenge += new
NSURLConnection.ConnectionDidReceiveAuthenticationChallengeEventHandler(d_ConnectionDidReceiveAuthenticationChallenge);
d.ConnectionDidReceiveData += new
NSURLConnection.ConnectionDidReceiveDataEventHandler(d_ConnectionDidReceiveData);
d.ConnectionDidReceiveResponse += new
NSURLConnection.ConnectionDidReceiveResponseEventHandler(d_ConnectionDidReceiveResponse);
d.ConnectionWillCacheResponse += new
NSURLConnection.ConnectionWillCacheResponseEventHandler(d_ConnectionWillCacheResponse);
d.ConnectionWillSendRequestRedirectResponse += new
NSURLConnection.ConnectionWillSendRequestRedirectResponseEventHandler(d_ConnectionWillSendRequestRedirectResponse);
d.ConnectionDidSendBodyData += new
NSURLConnection.ConnectionDidSendBodyDataTotalBytesWrittenTotalBytesExpectedToWriteEventHandler(d_ConnectionDidSendBodyData);
});
NSURLConnection.NSURLConnectionEventDispatcher @delegate =
new NSURLConnection.NSURLConnectionEventDispatcher();
assignment(@delegate);
NSURLConnection conn = new NSURLConnection(req, @delegate);
Also added some logging to
NSURLConnectionEventDispatcher.RespondsToSelector() and I do see in the log
some requests to see if my delegate responds to:
selector
connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:
selector connection:canAuthenticateAgainstProtectionSpace:
selector connection:needNewBodyStream:
But only these 3. I added the ConnectionDidSendBodyData event, which is
also not called. I did do the same code in obj-c and the same 3 selectors
are checked plus a few extra. And the didSendBodyData selectors is called
in obj-c.
Because of the logging I know that the @delegate is being inspected by
NSURLConnection. But after those 3 no selectors are called on
NSURLConnectionEventDispatcher. I even tried just returning true to
respondsToSelector hoping to raise an error, but that did not.
Any help would be greatly appreciated.
