I am new to iOS development and I was trying to implement the pull to refresh in iOS 6. Well looking for a solution, I stumbled across this blog post and found it to be very helpful, http://www.intertech.com/Blog/Post/iOS-6-Pull-to-Refresh-(UIRefreshControl).aspx. It lays out the steps to implementing pull to refresh in a way that is easy to follow. Anyone looking to do this themselves in iOS 6 should check out the blog.
The UIRefreshControl is only useable with a Table View currently. There are a few steps to follow to successfully add a refresh control:
1. Create a callback method to handle your refresh logic. The callback method should be invoked when a user pulls down on the table view. The signarture of the method should take one parameter: a pointer to the UIRefreshControl.
Note: Steps 2-4 are all done within the Table View Controller’s viewDidLoad method.
2. Instantiate the UIRefreshControl with a basic "alloc/init".
3. Connect an action to the refresh control to invoke your callback method when the ValueChange event is fired.
4. Add the refresh control to the Table View Controller's "refreshControl" property.
