The AUDragLoadingView and the Aupullloadingview provide the loading style when the page is pulled up or down.
The following controls are not customized for businesses and must be switched to the AUPullLoadingView or AUDragLoadingView control.
CommonUI: ODRefreshControl, APCircleRefreshControl, EGORefreshTableHeaderView, and APNextPagePullView.
