Question

这可能是一个奇怪的问题，我希望以前有人拥有它。

我使用以下代码向我的TableView添加了一个SegmentControl：

   UIView *headerView = [[UIView alloc] init ];
   [headerView addSubview:resultsSegment];
    self.tableView.tableHeaderView = headerView;

    resultsSegment.frame = CGRectMake(45, 123, 250, 40);
    [self.tableView addSubview:resultsSegment];

在这些论坛的帮助下，前三行使得TableView标题的Segment部分成为滚动的原因。大。

但是，这会禁用点击SegmentControl的功能。

添加最后一行再次成为可能。

SegmentControl执行很棒的UNTIL滚动，然后它变得非常无响应。它不会引起任何错误，它最终会接受来自手指的按压，但你必须在它切换之前点击它5/6次。

如果有人能够对此有所了解，那就太棒了

您需要的任何额外信息我很乐意提供！

Answer 1

这里可能存在的问题是你有一个segmentControl，但你把它作为子视图添加到tableHeaderView和tableView。

Answer 2

通过将以下代码从viewDidLoad方法移动到titleForHeaderInSection

，我解决了滚动时无响应的SegmentControl问题

 resultsSegment.frame = CGRectMake(45, 123, 250, 40);
            [self.tableView addSubview:resultsSegment];

现在看起来像这样：

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;

{
    switch (section) {
        case 0:
            return @"";
            break;
        case 1:
            resultsSegment.frame = CGRectMake(45, 123, 250, 40);
            [self.tableView addSubview:resultsSegment];
            return @"";
            break;
        case 2:

            return @"";
            break;
        default:
            return @"Section Count Error";
            break;
    }


}

滚动TableView会影响SegmentControl的响应时间
