迅捷:使用"/"在文件名中使用createDirectoryAtPath进行斜杠 [英] Swift: Using "/" slash in filename with createDirectoryAtPath

问题描述

我有一个名为我的项目"的文件夹.当我尝试调用createDirectoryAtPath时，我得到了两个文件夹，分别是项目"和项目".

I have a folder called "My / Project". When I try to call createDirectoryAtPath I get two folders created "My " with a subfolder of " Project".

我查看了终端如何表示这一点:

I have looked at how the terminal represents this:

/Users/currentuser/Documents/Projects/My\ \:\ Project

这是我的代码:

let projectName = "My / Project"
let path:NSString = "/Users/currentuser/Documents/Projects/"

let fullPath:NSString = path.stringByAppendingPathComponent(projectName)

if (!NSFileManager.defaultManager().fileExistsAtPath(fullPath:NSString))
{
    do 
    {
         try NSFileManager.defaultManager().createDirectoryAtPath(fullPath:NSString, withIntermediateDirectories: true, attributes: nil)
    }
    catch
    {
    }
}

我也尝试过:

projectName.stringByReplacingOccurrencesOfString("/", withString: "\:")

匹配终端，但是Xcode抱怨无效的转义序列.

to match the terminal but Xcode complains about an invalid escape sequence.

更新1:对文件夹名称进行编码也无法正常工作.

Update #1: Encoding the folder name also failed to work.

let encodedPath = projectName.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLUserAllowedCharacterSet())
let fullPath2:NSString = path.stringByAppendingPathComponent(encodedPath!)
NSFileManager.defaultManager().fileExistsAtPath(encodedPath!)

做到这一点的最佳方法是什么?

What is the best way of doing this?

推荐答案

斜杠是文件系统中的路径分隔符，不允许使用 在文件名组件中.

The slash is the path delimiter in the file system, and not allowed in file name components.

但是，OS X Finder允许使用带斜杠的文件名，并且可以使用 通过在显示的文件名的斜杠"/"和文件系统中的冒号:"之间进行翻译. (因此，您不能使用冒号 Finder中的文件名.)

The OS X Finder however allows file names with a slash, and that works by translating between the slash "/" for displayed file names and the colon ":" in the file system. (As a consequence, you cannot use the colon for file names in the Finder.)

因此，"My/Project"文件夹在文件系统中存储为"My:Project"，并且应使用 unscaped 冒号":"替换文件名中的"/". 解决您的问题.

The folder "My / Project" is therefore stored in the file system as "My : Project", and replacing "/" in the file name with an unescaped colon ":" should solve your problem.

(冒号在外壳中有特殊含义，这就是为什么您看到 \:在终端中.)

(The colon has a special meaning in the shell, and that is why you see \: in the Terminal.)
