点击时修改 UIT 可访问Cell 的文字
原标题:change text of a UITableViewCell when tapped

我试图更新一个UITableViewCell,

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    if ([[self.menuItems objectAtIndex:aPath.row] isEqualToString:@"AirPrint Order"]) {

        UITableViewCell *cell = (UITableViewCell *)[tableView cellForRowAtIndexPath:indexPath];
        cell.textLabel.text=@"Generating Order Receipt";
        NSArray *nsa = [[NSArray alloc] initWithObjects:indexPath, nil];
        [tableView reloadRowsAtIndexPaths:nsa withRowAnimation:UITableViewRowAnimationNone];
    }
}

即使调试器在调试器里 确实能进入我的体内 如果声明,但单元格文本没有发生什么。

最佳回答

当您调用 loadRowsAtIndexPath 时,它实际上调用 cellForRowAtIndexPath: 并重新装入单元格,删除您在 didSelectRowAtIndexPath 中应用的修改。我建议您做的是:在 SelectRowAtIndexPath 方法中更新您的数据,并在 CelforRowAtIndexPath 中读取。
