Add pull to refresh

__weak typeof (self) wself = self;
//UITableView
[self.tableView addPullToRefresh:^{
  [wself pullToRefresh];
}];

//UICollectionView
[self.collectionView addPullToRefresh:^{
  [wself pullToRefresh];
}];

//UIWebView
[self.webView.scrollView addPullToRefresh:^{
   [wself.webView reload];
}];

End Pull to refresh

//UITableView
[self.tableView endRefreshing];

//UICollectionView
[self.collectionView endRefreshing];

//UIWebView
[self.webView.scrollView endRefreshing];

//UITableView
[self.tableView addInfiniteScrolling:^{
  [wself loadMoreRefresh];
}];

//UICollectionView
[self.collectionView addInfiniteScrolling:^{
  [wself loadMoreRefresh];
}];

End Loading more

//UITableView
[self.tableView endLoadingMore];

//UICollectionView
[self.tableView endLoadingMore];

//UITableView
[self.tableView noticeNoMoreData];

//UICollectionView
[self.tableView noticeNoMoreData];

[self.scrollView startRefreshing];

self.tableView.ln_header.animator.trigger = 100;
