Ios 尝试从具有发起人UITableView的ViewController分离到另一个ViewController

我对iOS编程还是新手，我正在尝试实现一个应用程序，为参加周末黑客大赛的学生显示信息。我目前正在处理一个表格，其中包含赞助商列表，当您单击一个赞助商披露按钮时，我希望它转到另一个页面，该页面仅显示赞助商的名称和包含其网站的web视图

我认为我已经适当地设置了prepareForSegue方法，但当我尝试在iOS模拟器中进行选择时，什么都没有发生。有人能看看我的代码并告诉我是否遗漏了什么吗

SponsorMasterViewController.h文件从这里开始

SponsorDetailViewController.h文件从这里开始

我看到您已经在故事板中定义了从masterViewController到DetailViewController的推送序列

要执行此步骤，您需要实现UITableView委托方法，特别是tableView:DidSelectRowatineXpath:

PrepareForSegue是为segues做准备，它不执行segues

但是，当您点击“披露详细信息”按钮时，不会发生这种情况，但如果您遵循此实现，则当您点击单元格时会发生这种情况

您应该实施

-voidtableView:UITableView*tableView访问按钮以indexPath:NSIndexPath*indexPath格式显示

有点像

-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier:@"sponsorSegue" sender:[self.allSponsors objectAtIndexPath: indexPath]];
}

然后把你准备的步骤改成

sponsorDetailController.spon=发送方

啊，我明白了。谢谢你的澄清
