A tweet can be opened by Safari with a link of this format:
http://twitter.com/1Direction_X/statuses/197752514391715842
On iOS 5, Twitter is built-in. How can I open the above tweet using the native Twitter app called from my app?
This is how you access other apps from your own. Just find the proper url to send for accessing status. I've included a list that should have most of the important ones. Including status finding.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"twitter://status?id=12345"]];
twitter://user?screen_name=lorenb
twitter://user?id=12345
twitter://status?id=12345
twitter://timeline
twitter://mentions
twitter://messages
twitter://list?screen_name=lorenb&slug=abcd
twitter://post?message=hello%20world
twitter://post?message=hello%20world&in_reply_to_status_id=12345
twitter://search?query=%23hashtag
Note: It can be important to make sure the user has twitter installed or this will cause a crash. So I recommend adding this in an if statement before you try to send them to twitter.
[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"twitter://"]];
