Cannot post to twitter via Twitter-OAuth-iPhone in a NSThread -

i started using ben gottlieb's twitter-oauth-iphone class post status updates in app. have done so, when executed on application's main thread. but, when throw in "nsthread detachnewthreadselector" post never makes twitter. processes fine , proper [connection identifier], results never make on twitter. idea how can run in thread without bringing main thread?

code added tweet method

-(void)tweet{   if([_engine isauthorized]){     [_engine sendupdate:@"tweeting"];   }   }   

doesn't work:

[nsthread detachnewthreadselector:@selector(tweet) totarget:self withobject:nil];   

does work (from main app):

[self tweet];   

does work (from within thread):

[self performselectoronmainthread:@selector(tweet) withobject:nil waituntildone:no];
