[wself loadMoreRefresh];
}];

[self.collectionView addInfiniteScrolling:^{
[wself loadMoreRefresh];
}];
End Loading more

- (void)endRefreshAnimation_DIY:(LNRefreshComponent *)view;
- (void)startRefreshAnimation_DIY:(LNRefreshComponent *)view;
- (void)refreshView_DIY:(LNRefreshComponent *)view progress:(CGFloat)progress;
