Why don't you also use a block to return the response? Something like:

-(void)sendTweet:(Tweet *)tweet withResponseCallback:(void (^)(NSMutableDictionary *responseDictionary))callback {

    NSLog(@"Sending tweet");

    NSMutableDictionary *twitterRequestDictionary = [[NSMutableDictionary alloc] init];
    [twitterRequestDictionary setObject:tweet.tweetBody forKey:@"status"];

    TWRequest *request = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"https://api.twitter.com/1/statuses/update.json"]
                                             parameters:twitterRequestDictionary
                                          requestMethod:TWRequestMethodPOST];
    [request setAccount:self.userAccount];


    [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
        NSMutableDictionary *responseDictionary  = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:nil];
        NSLog(@"Response dictionary: %@", responseDictionary);
        callback(responseDictionary);
    }];
}
