14. Salesforce Connect API
• Use Rest based Connect API for interaction with Force.com
• Each Resource in Force.com REST API is a named URI –
accessible using HEAD, GET, POST, PATCH or DELETE.
• Examples:
• Get user feed, followers, following etc.
• Perform a query or search
• Update or delete records
https://na1.salesforce.com/services/data/v25.0/sobjects/

15. Example of using Chatter REST API
The following code snippet uses the 'me' keyword to retrieve the
current users news feed:
NSString *res_url = [NSString
stringWithFormat:@"%@/services/data/v22.0/chatter/feeds/new
s/me/feed-items", [auth.parameters
objectForKey:@"instance_url"]];

16. Using iOS v5 and v6 SDK
Integrating with Social Media

17. iOS v5 Social Media Support
• Starting with iOS v5 Apple provided Twitter Framework built in
the SDK
• TWTweetComposeViewController inherits from UIViewController
and provides a very simple mechanism to tweet

18. iOS v5 – Sending Tweet – UI Integration
Check for service availability
 canSendTweet
Create a view controller
Supply a completion handler
Present modally

19. iOS v5 – Using TWTweetComposeViewController
- (void)tweetThis:(id)sender{
- self.tweetController = [[TWTweetComposeViewController alloc] init];
- [self.tweetController setInitialText:@"Tweeting Tweeting!"];
- [self.tweetController setTitle:@"Tweet Please"];
- [self.tweetController setCompletionHandler:^(TWTweetComposeViewControllerResult result) {
- NSString *output;
- switch (result) {
- case TWTweetComposeViewControllerResultCancelled:
- output = @"Tweet Cancelled";
- break;
- case TWTweetComposeViewControllerResultDone:
- output = @"Tweet Done";
- break;
- default:
break;
- }
- // Dismiss the tweet compose view controller
- [self.navController dismissModalViewControllerAnimated:YES]; }];
- [self.navController presentModalViewController:self.tweetController animated:YES]; }
