• Many (as of this writing, all) of these iOS-Native components originally appeared in Salesforce for iPad, a free, unofficial, unsupported, open-source app that's available on GitHub.

0. These components have a required dependency on the Force.com Mobile SDK for iOS. First ensure you have it added to your app.
1. Grab the component source code: git clone https://github.com/ForceDotCom/MobileComponents.git
2. iOS Native components are in the iOS-Native directory. Copy the component(s) of your choice into your xcode project.

A UIBarButtonItem intended to make it easy to create a follow/unfollow toggle between the running user and any other user or Chatter-enabled record.

Usage:

1. Create a new button with the parent object's ID (the id of the user/record to follow/unfollow). Use the built-in constructor. FollowButton *myFollowButton = [FollowButton followButtonWithParentId:@"00530000001emdl"];
2. Set the follow button's delegate to your viewcontroller (myFollowButton.delegate = self;), add the FollowButtonDelegateto your viewcontroller's header, and add the button itself to your view.
3. Once your view has loaded, instruct your follow button to load its current follow state. [myFollowButton loadFollowState];
4. When the user taps the button, it will call your delegate with followButtonWillChangeState and followButtonDidChangeState. Salesforce for iPad uses these delegate events to swap out the FollowButton in favor of an activity loading spinner to indicate to the user that a network operation is in progress, but that's entirely optional. When the follow or unfollow action is completed, the button should update its state and displayed text.
