Question

Essentially what I want is for the app, once the user has allowed access to their Twitter account, to be able to tweet whatever the user has selected in a UITableView. Ideally I’d like to use the Twitter framework in iOS 5, but the main issue I’m having is the modal view controller for tweeting. Is this optional? Is it possible to tweet without it and if not, what do you suggest I do?

Thanks!

Answer 1

It’s definitely possible to tweet without it, the following is in production iOS 5 apps. It even takes the user to the requisite section of preferences if they haven’t registered an account.

- (void)postToTwitter
{
    // Create an account store object.
    ACAccountStore *accountStore = [[ACAccountStore alloc] init];

    // Create an account type that ensures Twitter accounts are retrieved.
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

    // Request access from the user to use their Twitter accounts.
    [accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) {
        if(granted) {
            // Get the list of Twitter accounts.
            NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];


            if ([accountsArray count] > 0) {
                // Grab the initial Twitter account to tweet from.
                ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
                TWRequest *postRequest = nil;

                postRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] parameters:[NSDictionary dictionaryWithObject:[self stringToPost] forKey:@"status"] requestMethod:TWRequestMethodPOST];



                // Set the account used to post the tweet.
                [postRequest setAccount:twitterAccount];

                dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {
                    [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                        dispatch_async(dispatch_get_main_queue(), ^(void) {
                            if ([urlResponse statusCode] == 200) {
                                Alert(0, nil, @"Tweet Successful", @"Ok", nil);
                            }else {

                                Alert(0, nil, @"Tweet failed", @"Ok", nil);
                            }
                        });
                    }];
                });

            }
            else
            {
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]];
            }
        }
    }];
}
