标识符存在时，接收器没有与之对应的segue

Question

For an iOS app, I have a story board and multiple controllers, and a segue going from controller GameClass to controller SettingsClass. The segue, in view Controller GameClass has an identifier called GameToSettings:

However, when I want to call the segue from my GameClass:

[self performSegueWithIdentifier: @"GameToSettings" sender: self];

I get the error message

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<GameClass: 0xcf0c550>) has no segue with identifier 'GameToSettings''

I tried many tips I found in other articles (like renaming the storyboard, cleaning the project, changing simulator format, giving another name to the segue, ), but the issue keeps coming.

I've uploaded a version of my code here: http://www.petits-suisses.ch/Issue.zip. Any suggestion of what I could continue trying ?
Thanks.

将你的项目上传到某个地方，然后在这里发布链接，我会查看它。 - duci9y

设置控制器是否嵌入导航控制器？ - hackerinheels

流程如下：导航控制器 -> 菜单控制器 --(presentViewController)-> 游戏控制器 --(performSegueWithIdentifier)-> 设置控制器。 - Laurent Crivello

Answer 1

您不应该以这种方式实例化视图控制器：

GameClass *myNewVC = [[GameClass alloc] init];

相反，使用

 [[UIStoryboard storyboardWithName:@"storyboard name" bundle:nil] instantiateViewControllerWithIdentifier:@"vc identifier">]

编辑： 请查看https://github.com/mac-cain13/R.swift

它将允许您使用自动完成、类型安全的方法轻松实例化： R.storyboard.main.myViewController
