Use UIActivityIndicatorView to provide a pull-to-refresh function for UIScrollView.

• iOS 8.0+
• Xcode 11.0+

Add pull-up trigger event

[tableView lc_addHeaderRefreshingWithActionHandler:^{

}];

Manual refresh

[tableView lc_beginHeaderRefreshing];

Add dropdown trigger event

[tableView lc_addFooterRefreshingWithActionHandler:^{
  
}];

Add dropdown trigger event

[tableView lc_beginFooterRefreshing];

Because only one UIActivityIndicatorView is created, lc_endRefreshing will end all refreshes.

[self.tableView lc_endRefreshing];

You can set horizontal or vertical refresh.

tableView.lc_refreshScrollDirection = LCRefreshScrollDirectionHorizontal;
