Requirements

iOS5 or later

Usage

1. add files under ISRefreshControl/ to your project.
2. import ISRefreshControl.h.

Usage of ISRefreshControl is almost the same as that of UIRefreshControl.
set refreshControl of UITableViewController in viewDidLoad.

self.refreshControl = (id)[[ISRefreshControl alloc] init];
[self.refreshControl addTarget:self
                        action:@selector(refresh)
              forControlEvents:UIControlEventValueChanged];

or just call addSubview:

UIScrollView *scrollView = [[UIScrollView alloc] init];
ISRefreshControl *refreshControl = [[ISRefreshControl alloc] init];
[scrollView addSubview:refreshControl];
[refreshControl addTarget:self
                   action:@selector(refresh)
         forControlEvents:UIControlEventValueChanged];

NOTE: currently, ISRefreshControl does not support setting on storyboard.

How it works

iOS6

works as real UIRefreshControl.
the constructor of ISRefreshControl returns an instance of UIRefreshControl.

iOS5

imitates UIRefreshControl. ISRefreshControl sends UIControlEventValueChanged when content offset of UITableView overs threshold. UITableViewController is extended to send content offset to ISRefreshControl.
