问题描述
自定义的UICollectview:
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];//[refreshControl beginRefreshing];refreshControl.tintColor = [UIColor colorWithWhite:0.9 alpha:0.35];[self addSubview:refreshControl];self.refreshUp = refreshControl;
在数据加载时调用:
[self.refreshUp beginRefreshing];[self setContentOffset:CGPointMake(0, self.contentOffset.y - self.refreshUp.frame.size.height) animated:YES];//-self.refreshUp.frame.size.height dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{[self loadNetData]; });
没有转圈加载的动画效果,一直是白屏,然后知道数据显示完成。而我是需要转圈那个加载工程的,有没有大神解答一下,在此谢过了。
