iOS开发之下拉刷新和上拉加载更多

- (void)PullDownLoadEnd {
    _count = 1;
    _tableView.canPullUp = YES;
    [self startDownloadData];
    [_tableView reloadData];
    [_tableView stopLoadWithState:PullDownLoadState];
}

- (void)PullUpLoadEnd {
    _count += 1;
    if (_count > 10) {
        _tableView.canPullUp = NO;
    }
    [self startDownloadData];
    [_tableView reloadData];
    [_tableView stopLoadWithState:PullUpLoadState];
}



*注意事项：

    if(self.interceptor.downView)
//        [self.interceptor.downView setFrame:CGRectMake(0, self.contentSize.height, self.frame.size.width, 300)];
        [self.interceptor.downView setFrame:CGRectMake(0, self.contentSize.height - 140 - 64 - 49, self.frame.size.width, 300 - 140 - 64 - 49)];

用此类实现下拉加载时，默认显示的视图为整个self.view,即：

 [self.interceptor.downView setFrame:CGRectMake(0, self.contentSize.height, self.frame.size.width, 300)];

需要改为：

[self.interceptor.downView setFrame:CGRectMake(0, self.contentSize.height - 140 - 64 - 49, self.frame.size.width, 300 - 140 - 64 - 49)];
