Question

我想要它，然后触摸部分标题然后跳到本节的结尾。我怎么能这样做？有什么建议？干杯

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
    UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
    [headerView setBackgroundColor:[[UIColor grayColor] colorWithAlphaComponent:0.7]];
    UILabel *titleInSection = [[[UILabel alloc] initWithFrame:CGRectMake(50, 3, tableView.bounds.size.width/3, 20)] autorelease];
    [titleInSection setBackgroundColor:[[UIColor grayColor] colorWithAlphaComponent:0]];
    [titleInSection setTextColor:[UIColor whiteColor]];
    if (isSectionLoad == YES){
        [categoryData retain];
        titleInSection.text = [categoryData objectAtIndex:section];
    }

    titleInSection.tag = section;
    UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(sectionTapped:)];
    [titleInSection addGestureRecognizer:recognizer];
    [recognizer release];

    [headerView addSubview:titleInSection];
    return headerView;
}

- (IBAction)sectionTapped:(UITapGestureRecognizer *)recognizer
{
    switch (recognizer.view.tag) {
        case 0:
            // do what you want for section with index 0
            NSLog(@"HELLO WORLD!!!");
            break;

        default:
            break;
    }
}

Answer 1

在您的委托中实施方法- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section。在此方法中，使用必要的子视图（标签，图像等）创建UIView。最后，只需将UITapGestureRecognizer添加到该视图即可。然后把它还给它。

例如：

- (IBAction)sectionTapped:(UITapGestureRecognizer *)recognizer
{
    switch (recognizer.view.tag) {
        case 0:
            // do what you want for section with index 0
            break;

        default:
            break;
    }
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UILabel *label;
    label.text = [NSString stringWithFormat:@"Section %d", section];
    label.tag = section;
    UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(sectionTapped:)];
    [label addGestureRecognizer:recognizer];
    [recognizer release];
    return  label;
}

这是一个老问题，但对这个问题有更好的答案：

请参阅此答案：https://stackoverflow.com/a/19173639/2371425

tl; dr - iOS6为我们提供了这些用于更改节标题/页脚属性的新方法。

-(void)tableView:(UITableView *)tableView 
    willDisplayHeaderView:(UIView *)view 
    forSection:(NSInteger)

- (void)tableView:(UITableView *)tableView
    willDisplayFooterView:(UIView *)view 
    forSection:(NSInteger)section

使用这些方法将UITapGestureRecognizer添加到headerView。

实施例

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section
{ 
    UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(sectionTapped:)];

    [view addGestureRecognizer:recognizer];

}
- (IBAction)sectionTapped:(UITapGestureRecognizer *)recognizer {
 NSLog(@"Tapped");
}

我们怎么能在UITable中使节标题可触摸？
