Integrate twitter into iOS 5 but maintain backwards compatibility with older iOS

Been following this great tutorial on how to integrate twitter into your app. I know there are other ways that programmers have used to integrate twitter before iOS 5 but my question is this:

My app supports iOS 3.0+ so if I integrate twitter using just the iOS 5 way of doing it, how will this affect my users that aren't using iOS 5? Will it even work for them?

Thanks!

Use weak linking and some code like the following:

 - (void)tweet
{
Class tweeterClass = NSClassFromString(@"TWTweetComposeViewController");

if(tweeterClass != nil) {   
    if([TWTweetComposeViewController canSendTweet]) {
        TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];
        tweetViewController.completionHandler = ^(TWTweetComposeViewControllerResult result) {
            if(result == TWTweetComposeViewControllerResultDone) {

            }
            [self dismissViewControllerAnimated:YES completion:nil];
        };

        [self presentViewController:tweetViewController animated:YES completion:nil];
    } else {
#if !(TARGET_IPHONE_SIMULATOR)
        [self displayAlert:@"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup."];
#else
        NSString *tweetString = [NSString stringWithFormat:@"http://mobile.twitter.com/home?status=%@%@", [self urlEncode:@"Check out this awesome pic: "] ,[self urlEncode:[_blobTweet.shortUrl absoluteString]]];
        NSURL *tweetURL = [NSURL URLWithString:tweetString];
        if ([[UIApplication sharedApplication] canOpenURL:tweetURL]) { 
            [[UIApplication sharedApplication] openURL:tweetURL]; 
        }
#endif
    }
} else {        
    // no Twitter integration could default to third-party Twitter framework

}
}

@end

The official API framework wouldn't work unfortunately as the twitter app/integration is only available in iOS 5

A good solution is to use ShareKit, a free API that allows you to integrate twitter, facebook and other social network support.

If you are OK by only making Twitter available for iOS 5 users, you can check if Twitter is available with this:

// Don't forget to import Twitter!
#import <Twitter/Twitter.h>
....
if([TWTweetComposeViewController class] != nil) {
    // your code here
}

Also, make sure that when adding the Twitter framework you set it as optional.

You should look into DETweetComposeViewController. We built it just for this purpose. It is an iOS4 compatible re-implementation of the TWTweetComposeViewController.
