如何检索详细信息披露按钮的视图?

问题描述

我有一个带有单元格的 UITableView，带有详细信息披露指示符 (UITableViewCellAccessoryDe​​tailDisclosureButton).

I have a UITableView with cells on it with detail disclosure indicator (UITableViewCellAccessoryDetailDisclosureButton).

我需要详细信息披露按钮的视图(以从中显示一些自定义弹出菜单)，但它始终为空.为什么?

I need the detail disclosure button's view (to show some custom popup menu from it), but it is always null. Why?

-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
[self showMenu: cell.accessoryView];
NSLog(@"%@",cell.accessoryView);}

如何将公开按钮的视图检索为 UIVIew*?(注意，我有披露按钮，并为它触发了点击事件)

How an I retrieve disclosure button's view as UIVIew*?(note, i have the disclosure buttons and tap event is fired for it)

提前致谢！

推荐答案

您可以通过检查单元格子视图找到附件按钮:

You can find the accessory button by checking the cells subviews:

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
    //[self showMenu: cell.accessoryView];
    NSLog(@"%@",cell.accessoryView);

    NSArray *subviews = [cell subviews];

    for (UIView *subview in subviews) {
        if ([subview isKindOfClass:[UIButton class]]) {
            NSLog(@"This is that button");
        }
    }
    NSLog(@"Subviews: %@", subviews);
}
