    copied!<p>I am thinking that how can I make a class for twitter or facebook or anything. So just I import that class to my project and it start working with one code. For example. If I use twitter framework then I have to write its functions. I just want to make a class of that funcation which will work on my all future projects by just importing it. example:</p> <p>Any class or anything:</p> <pre><code>-(void)shareOnTwitter:(NSString *)text withUrl:(NSURL *)url withImage:(UIImage *)image { // ALL TWITTER Code HERE; } </code></pre> <p>And in my Main viewController of any project:</p> <pre><code>- (IBAction)socialBtn:(id)sender { [self shareOnTwitter:@"This is Text" withUrl:nil withImage:nil]; } </code></pre> <p><strong>UPDATE: Just tried Category way but no response return, any idea where I am wrong?:</strong></p> <p><strong>UIViewController+CustomMethods.h</strong></p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import &lt;Social/Social.h&gt; @interface UIViewController (CustomMethods) -(void)shareOnTwitter:(NSString *)text withUrl:(NSURL *)url withImage:(UIImage *)image; @end </code></pre> <p><strong>UIViewController+CustomMethods.m</strong></p> <pre><code>#import "UIViewController+CustomMethods.h" @implementation UIViewController (CustomMethods) -(void)shareOnTwitter:(NSString *)text withUrl:(NSURL *)url withImage:(UIImage *)image { if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) { SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; [tweetSheet setInitialText:text]; [tweetSheet addImage:image]; [tweetSheet addURL:url]; [self presentViewController:tweetSheet animated:YES completion:nil]; } else { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry" message:@"You can't Post a Status right now, make sure your device has an internet connection and you have at least one Twitter account setup" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; } } @end </code></pre> <p><strong>mainViewController:</strong></p> <pre><code>NSString *title = [webViewOutlet stringByEvaluatingJavaScriptFromString:@"document.title"]; NSURL *url = [[webViewOutlet request] URL]; [self shareOnTwitter:title withUrl:url withImage:nil]; </code></pre>
