DxRefreshView_OC

模仿锤子手机的下拉刷新效果

Demo:

Usage:

_scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
DxRefreshView *refreshHeader = [[DxRefreshView alloc] init];
refreshHeader.color = [UIColor blueColor];
refreshHeader.actionHandler = ^{
     //刷新数据
};

刷新完成之后：

[_scrollView.refreshHeader endRefreshing];

不通过下拉触发，直接开始刷新:

[_scrollView.refreshHeader beginRefreshing];
