I follow the instruction to the letter and I get an error saying"no such file or directory" but the file is listed under classes and the spelling is identical.

推荐答案

您收到该错误是因为 Xcode 找不到您尝试导入的文件.

You are getting that error because Xcode cannot find the file you are trying to import.

正确用法:

#import "RootViewController.h"

或

#import <Foundation/Foundation.h>

您还必须确保您尝试导入的文件在您的项目列表中.如果您尝试导入的文件不在此列表中，那么您将始终收到此错误.

You also have to make sure that the file(s) you try to import are in your Project list. If the file you are trying to import is not in this list, then you will always receive this error.
