我是新手，因此代码可能会出现很多错误。问题是。当我单击单元格打开detailviewcontroller时，但不显示我在plist中设置的细节。 并且不要显示任何错误。

TableViewController.h：

@interface NamesTableViewController : UITableViewController <UISearchDisplayDelegate, UISearchBarDelegate>

它不起作用，因为：

  1. 未启动arrayPlace
  2. 由于＆＃34; copy＆＃34;而arrayPlace定义设置了一个数组而不是可变数组。指令
  3. 解决方案是修复但不能解决问题。更改didSelectRowAtIndexPath

    4. <强>解决方案
