【问题描述】：
我是新手，所以代码中可能有很多错误。问题是。当我单击单元格打开detailviewcontroller.但不显示我在plist中设置的详细信息时。 并且不显示任何错误。
TableViewController.h：
@interface NamesTableViewController : UITableViewController <UISearchDisplayDelegate, UISearchBarDelegate>
@property (strong, nonatomic) IBOutlet UISearchBar *searchBar;
@end
TableViewController.m：

_textPlace.text = _titleGet;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
和属性列表：
<plist version="1.0">
<dict>
<key>A</key>
<dict>
<key>Azer Huseynov</key>
<dict>
<key>Company</key>
<string>test ac</string>
<key>Position</key>

<key>Email</key>
<string>test ae</string>
<key>Number</key>

<key>Photo</key>
<string>test ai</string>
</dict>
</dict>
<key>B</key>

帮帮我！
【问题讨论】：
-
在推动视图控制器显示文本“Hello world”之前是否设置
titleGet像“Hello world”这样的常量值？请在 'DetailsViewController' 内的viewDidLoad中添加日志以供进一步检查。 -
我觉得inn这个概念不需要Plist，你可以直接把字段移到下一页
-
@Anbu.Karthik 怎么办？
