我正在创建一个iOS应用程序，它是一个目录系统，在第一页上我加载数据，例如tableview中的某些状态列表（来自sqlite数据库）。单击状态时，只有特定状态下的区域必须显示在详细视图的tableview中。我的问题是，当点击每个区时，该区的电话号码必须显示在下一个视图控制器中。有人可以帮忙吗？
这是第一次观看。

答案 0 :(得分：0)
你需要将包括phoneNumbers的数据从第一个stateViewController传递到District然后从District传递给DetailsPage ...我建议传递一个NSdictionary，其中包含从一个视图到另一个视图的数据，例如......在第二个ViewController中声明一个全局字典as mainDictionary ..
并在didSelectRowAtIndexPath中将数据传递为
self.ddetails = [self.storyboard instantiateViewControllerWithIdentifier:@"phonelistViewController"] ;
_ddetails.mainDict=AllThe Details;
使用PhoneNumbers做同样的事情
