EGOTableViewPullRefresh实现下拉刷新

首先定义EGORefreshTableHeaderView *_refreshView和BOOL _isRefresh;实现EGORefreshTableHeaderDelegate

//定义下拉刷新试图
_refreshView = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0, -[UIScreen mainScreen].bounds.size.height, 320, [UIScreen mainScreen].bounds.size.height)];
_refreshView.delegate = self;
[self.tableView addSubview:_refreshView];

//实现scroller的配置
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    [_refreshView egoRefreshScrollViewDidScroll:scrollView];
}
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate {
    [_refreshView egoRefreshScrollViewDidEndDragging:scrollView];
　　//实现上啦加载更多的选项
    if (scrollView.contentOffset.y+scrollView.frame.size.height>scrollView.contentSize.height+40) {
    }
}

//实现它的代理
- (NSDate *)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView *)view {
    return [NSDate date];
}
- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView *)view {
    return _isRefresh;
}
- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView *)view {
    _isRefresh = YES;
　　/*刷新的其他操作*/
}

//在结束刷新的地方调用
_isRefresh = NO;
[_refreshView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];
