Drop-down refresh, pull-up load

If the first access to the view, for some reason, the data array is empty, so TableView alive CollectionView is not visible, naturally can not pull up, pull down action, the current thought is to perform a refresh in Viewdidapplear

[Tableviewtriggerpulltorefresh];

For CollectionView loading successful if Reloaddata CollectionView will automatically return to top, so want to see new data and continue to pull down, very distressed

Reason to find

if (WeakSelf.collectionView.pullToRefreshView) {

[WeakSelf.collectionView.pullToRefreshView stopanimating];

}

if (WeakSelf.collectionView.infiniteScrollingView) {

[WeakSelf.collectionView.infiniteScrollingView stopanimating];

}
