objective-c - 射击失败

我有一个storyboard

在此storyboard有一个UITableViewController它使用自定义类 comMasterViewController。

使用storyboard ,我只需从 UITableViewController 按住 Control 键拖动即可到另一个场景。

模态 segue被 build 。我将其标识符更改为“loadingDataSegue”。

在我的UITableViewController代码,我触发这一行:

[self performSegueWithIdentifier:@"loadingDataSegue" sender:nil];

我收到:

Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: 'Receiver (<comMasterViewController: 0x1b6290>) has no segue with
identifier 'loadingDataSegue''

什么地方没有正确连接?

感谢您的帮助

编辑:我很确定我链接的是 TVC,而不是任何 subview 。查看 Storyboard代码,我看到以下内容:

<tableViewController storyboardIdentifier="comMasterViewController"
title="comMasterViewController" clearsSelectionOnViewWillAppear="NO" id="19"
userLabel="comMasterViewController" customClass="comMasterViewController"
sceneMemberID="viewController">

在底部,作为 <tableViewController> 的子标签而不是它的任何 subview :

<connections>
<segue destination="UCh-sM-lba" kind="modal" identifier="loadingDataSegue"
id="epP-jH-GLZ"/>
</connections>

这是堆栈跟踪:

最佳答案

确保您没有从 TableView Row 或 UIButton 中拖动 Segue,而是从 VC 本身中拖动。如果您有疑问,请删除 segue 并重新连接。如果这不能解决您的问题,还要检查拼写错误(包括大小写)。
