Very useful for refreshing table and collection views that contain most recent items at the bottom. For example in chats.

#import <CCBottomRefreshControl/UIScrollView+BottomRefreshControl.h>

...

UIRefreshControl *refreshControl = [UIRefreshControl new];
refreshControl.triggerVerticalOffset = 100.;
[refreshControl addTarget:self action:@selector(refresh) forControlEvents:UIControlEventValueChanged];
self.tableView.bottomRefreshControl = refreshControl;

- (void)refresh {
    // Do refresh stuff here
}
