I have an app that uploads to Google Spreadsheets via the GData ObjC client for Mac/iPhone. It works fine as is. I'm trying to get the upload portion on its own thread and I'm attempting to call the upload method on a new thread.

Look:

-(void)establishNewThreadToUpload {
    [NSThread detachNewThreadSelector:@selector(uploadToGoogle) toTarget:self withObject:nil];
}

-(void)uploadToGoogle {
    NSAutoReleasePool *pool = [[NSAutoReleasePool alloc] init];
    //works fine
    [helper setNewServiceWithName:username password:password];
    //works fine
    [helper fetchUserSpreadsheetFeed];
    //inside the helper class, fetchUserSpreadsheet feed calls ANOTHER method, which
    //calls ANOTHER METHOD and so on, until the object is either uploaded or fails
    //However, once the class gets to the end of fetchUserSpreadsheetFeed
    //control is passed back to this method, and
    [pool release];
    //is called.  The thread terminates and nothing ever happens.
}

If I forget about using a separate thread, everything works like it's supposed to. I'm new to thread programming, so if there's something I'm missing, please clue me in!

Thanks!
