简单易用的上拉加载、下拉刷新组件，可自定义头部和底部视图，可单独实现下拉刷新，上拉加载更多。
Latest：Swift实现，只实现了下拉刷新，还没有实现上拉加载更多
/** SEE SYRefreshTable (https://github.com/reesun1130/SYRefreshTable) for instructions.
* USE SYRefreshTable LIKE:
* @interface ViewController : SYTableViewController
* OVERRIDE refresh、loadMore、scrollViewDidScroll
*/
////////// 只需实现这三个方法 即可实现下拉刷新，上拉加载更多 #Pull to Refresh
* - (BOOL)refresh
{
if (![super refresh])
return NO;
self.pageCount = 1;
[lockLoadData lock];
[self performSelector:@selector(loadItemData) withObject:nil afterDelay:0.01];
[lockLoadData unlock];
return YES;
}
#Load More
* - (BOOL)loadMore
{
if (![super loadMore])
return NO;
self.pageCount ++;
[lockLoadData lock];
[self performSelector:@selector(loadItemData) withObject:nil afterDelay:0.01];
[lockLoadData unlock];
return YES;
}
#UIScrollViewDelegate Method
* - (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[super scrollViewDidScroll:scrollView];
}
