At which point does the code behaving as you expect? Can you post the logs? – Turves

I get the EXC_BAD_ACCESS Error....and error showing STTwitterErrorDomain code:220 Your Credentials do not allow to this resource.STHTTPRequest-code:403 – Iodic

You cannot post if you haven't authenticated a user. Also, you shouldn't re-instantiate STTwitterAPI in the successBlock. See the STTwitterDemoiOS and STTwitterDemoOSX for working examples. – Turves

you haven't authenticated a user. means how to get authenticate my user ?and in successBlock i put like this successBlock:^(NSDictionary *status) { NSLog(@"===1===Sucess"); }errorBlock:^(NSError *error) { NSLog(@"_____ERROR ===1==%@",error);}]; even though getting STTwitterErrorDomain code:220 – Iodic
