10. Twitter iOS 5 build in Twitter framework Tweet with dialog // Set up the built-in twitter composition view controller. TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init]; // Set the initial tweet text. See the framework for additional properties that can be set. [tweetViewController setInitialText:@"Hello. This is a tweet."]; // Create the completion handler block. [tweetViewController setCompletionHandler:^(TWTweetComposeViewControllerResult result) { NSString *output; switch (result) { case TWTweetComposeViewControllerResultCancelled: output = @"Tweet cancelled."; break; case TWTweetComposeViewControllerResultDone: output = @"Tweet done."; break; default: break; } // Dismiss the tweet composition view controller. [self dismissModalViewControllerAnimated:YES]; }]; // Present the tweet composition view controller modally. [self presentModalViewController:tweetViewController animated:YES]; Sunday, 13 May, 12
11. Twitter Tweet with custom message // 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]; // For the sake of brevity, we'll assume there is only one Twitter account present. if ([accountsArray count] > 0) { // Grab the initial Twitter account to tweet from. ACAccount *twitterAccount = [accountsArray objectAtIndex:0]; // Create a request, which in this example, posts a tweet to the user's timeline. TWRequest *postRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] parameters:[NSDictionary dictionaryWithObject:@"Hello. This is a tweet." forKey:@"status"] requestMethod:TWRequestMethodPOST]; // Set the account used to post the tweet. [postRequest setAccount:twitterAccount]; // Perform the request created above and create a handler block to handle the response. [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { NSString *output = [NSString stringWithFormat:@"HTTP response status: %i", [urlResponse statusCode]]; [self performSelectorOnMainThread:@selector(displayText:) withObject:output waitUntilDone:NO]; }]; } } }]; Sunday, 13 May, 12

13. Sina Weibo All authorization data is stored in KeyChain No need to handle token save in delegate // in WBEngine #define kWBURLSchemePrefix @"WB_" #define kWBKeychainServiceNameSuffix @"_WeiBoServiceName" #define kWBKeychainUserID @"WeiBoUserID" #define kWBKeychainAccessToken @"WeiBoAccessToken" #define kWBKeychainExpireTime @"WeiBoExpireTime" Sunday, 13 May, 12
14. Initialize weibo object Login Send Weibo After login WBEngine *engine = [[WBEngine alloc] initWithAppKey:[GeneralHelper weiboAppKey] appSecret:[GeneralHelper weiboAppSecret]]; WBEngine *weiBoEngine = [ad weiBoEngine]; weiBoEngine.rootViewController = self; [ad setWbEngineDelegate:self]; [weiBoEngine logIn]; [weiboEngine sendWeiBoWithText:@"message" image:self.image]; Sunday, 13 May, 12
