在情节提要中实现 tableView didSelectRowAtIndexPath

Question

您将如何在情节提要中实现 tableView didSelectRowAtIndexPath。我已经创建了一个创建表的视图控制器。当单击表格中的每个单元格时，我不知道在情节提要中如何使视图转换。

这是我最初以编程方式在该方法中的内容：

Show *show = [self.shows objectAtIndex:indexPath.section];
ShowContentItem *showItem = show.showContentItems[indexPath.row];

if ([showItem.contentType isEqualToString:@"Headline_Section"]) {
    HeadlinesViewController *headlinesVC = [[HeadlinesViewController alloc] init];
    headlinesVC.shows = [[NSMutableArray alloc] initWithObjects:show, nil];
    [self.navigationController pushViewController:headlinesVC animated:YES];
} else {
    NSInteger contentIndex = [self.storyPostContent indexOfObject:showItem];
    NSRange rangeForView = NSMakeRange(contentIndex, [self.storyPostContent count] - contentIndex );

    ShowContentViewController *showContentVC = [[ShowContentViewController alloc] init];
    showContentVC.contentList = [self.storyPostContent subarrayWithRange: rangeForView];

    [self.navigationController pushViewController: showContentVC animated:YES];
}

我将如何专门更改上面的代码以使用情节提要？

您可以控制从原型单元到目标控制器的拖动。然后在prepareForSegue 你做这样的事情：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"yourSegue"]) {
        yourViewController *destinationController = segue.destinationViewController;
        destinationController.someVariable = yourTable.indexPathForSelectedRow;
    }

}
