iOS UITableView headerView 没有隐藏

Question

我对 EGORefreshTableHeaderView 的使用有疑问:

如果我使用此代码，就可以了:

 - (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView *)view  
{
    _reloading = YES; 
    [self performSelector:@selector(refreshData) withObject:nil afterDelay:0.1f];
}

 - (void)refreshData
{
    _reloading = NO;
   [self.dataSourceArr removeAllObjects]; 
   [self.dataSourceArr addNewData];
   [self.egoHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.mainTableView];
   [self.mainTableView reloadData];
}

但是，当我使用此代码时，EGOrefreshHeaderView 将始终显示在 mainTableView 顶部，它不会隐藏:

 - (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView *)view  
{
    _reloading = YES; 
    [self refreshData];
}
 - (void)refreshData
{
    _reloading = NO;
   [self.dataSourceArr removeAllObjects]; 
   [self.dataSourceArr addNewData];
   [self.egoHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.mainTableView];
   [self.mainTableView reloadData];
}

Answer 1

代码的顶部部分运行如下:

// someone calls egoRefreshTableHeaderDidTriggerRefresh
    [_delegate egoRefreshTableHeaderDidTriggerRefresh:self]
        // sets up a refreshData to run after set period of time
    scrollView.contentInset = UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f);  // a
// some time later, refreshData runs
    [self.egoHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.mainTableView];
        [scrollView setContentInset:UIEdgeInsetsMake(0.0f, 0.0f, 0.0f, 0.0f)];  // b

底部运行如下:

// someone calls egoRefreshTableHeaderDidTriggerRefresh
    [_delegate egoRefreshTableHeaderDidTriggerRefresh:self]
        [self refreshData];
            [self.egoHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.mainTableView];
                [scrollView setContentInset:UIEdgeInsetsMake(0.0f, 0.0f, 0.0f, 0.0f)];  // b
    scrollView.contentInset = UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f);  // a

行a 和b 颠倒过来。即使更改是动画的，第二行也会覆盖第一行。

修复 1:

修改文件EGORefreshTableHeaderView.h

将 - (void)egoRefreshTableHeaderDidTriggerRefresh:... 更改为 - (bool)egoRefreshTableHeaderDidTriggerRefresh:...

修改文件EGORefreshTableHeaderView.m

更改-(void)egoRefreshScrollViewDidEndDragging:

if ([_delegate respondsToSelector:@selector(egoRefreshTableHeaderDidTriggerRefresh:)]) {
    if([_delegate egoRefreshTableHeaderDidTriggerRefresh:self]) {
       return;
    }
}

最后更改您的egoRefreshTableHeaderDidTriggerRefresh:

- (bool)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView *)view  
{
    _reloading = YES; 
    [self refreshData];
    return true;
}

修复 2:

如果你不想更改第三方代码，顶级版本是唯一的方法。您可以将持续时间指定为 0，这样选择器就会排队等待运行。
