+**Important**: The easiest way by far to share content from iOS app is to use `UIActivityViewControler`. If this is not enough for you, than ShareKit might be useful. Beware though - ShareKit is rather dated, although kept updated as time permits. Some services might have changed their API's or deprecated their SDK's in the meantime. It is a lot of work to keep ShareKit updated, and urgent help is needed, so you are more than welcome to test, add issues or open pull requests.

 ShareKit allows you to share content easily:
 ```objective-c
 - (void)myButtonHandlerAction {
 
     // Create the item to share (in this example, a url)
     NSURL *url = [NSURL URLWithString:@"http://getsharekit.com"];
     SHKItem *item = [SHKItem URL:url title:@"ShareKit is Awesome!" contentType:SHKURLContentTypeWebpage];
-    
+
     // Get the ShareKit action sheet
     SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];
 
     // ShareKit detects top view controller (the one intended to present ShareKit UI) automatically,
     // but sometimes it may not find one. To be safe, set it explicitly
     [SHK setRootViewController:self];
-
-    // Display the action sheet
-    if (NSClassFromString(@"UIAlertController")) {
-        
-        //iOS 8+
-        SHKAlertController *alertController = [SHKAlertController actionSheetForItem:item];
-        [alertController setModalPresentationStyle:UIModalPresentationPopover];
-        UIPopoverPresentationController *popPresenter = [alertController popoverPresentationController];
-        popPresenter.barButtonItem = self.toolbarItems[1];
-        [self presentViewController:alertController animated:YES completion:nil];
-        
-    } else {
-        
-        //deprecated
-        SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];
-        [actionSheet showFromToolbar:self.navigationController.toolbar];
-    }
 
+    // Display the action sheet
+    SHKAlertController *alertController = [SHKAlertController actionSheetForItem:item];
+    [alertController setModalPresentationStyle:UIModalPresentationPopover];
+    UIPopoverPresentationController *popPresenter = [alertController popoverPresentationController];
+    popPresenter.barButtonItem = self.toolbarItems[1];
+    [self presentViewController:alertController animated:YES completion:nil];
 }
 ```
 Everything else (user authentication, API calls, shareUI etc) is handled by ShareKit. Moreover, you can use and customise [SHKAccountsViewController](https://github.com/ShareKit/ShareKit/blob/master/Classes/ShareKit/UI/SHKAccountsViewController.h) (where users can login/logoff, displays username if someone is logged to a particular service) and [SHKUploadsViewController](https://github.com/ShareKit/ShareKit/blob/master/Classes/ShareKit/UI/SHKUploadsViewController.h) (similar to safari downloads, works with sharers able to report progress). For a brief introduction, check [the demo app](https://github.com/ShareKit/ShareKit-Demo-App). To know more about configuration options see [DefaultSHKConfigurator.m](https://github.com/ShareKit/ShareKit/blob/master/Classes/ShareKit/Configuration/DefaultSHKConfigurator.m). To know more about what type of content can be shared, see [SHKItem.h](https://github.com/ShareKit/ShareKit/blob/master/Classes/ShareKit/Core/SHKItem.h). To find out what services and actions are supported, check [Sharer implementations](https://github.com/ShareKit/ShareKit/tree/master/Classes/ShareKit/Sharers). To get a picture of what they are capable of check their .m (implementation) files, methods named:
