文件在
Swift Playground中无法读取.
如何使文件可读？
相同的代码在Xcode终端应用程序上运行良好,但在Swift Playground上失败.
演示代码如下.
import Foundation
println("Hello,World!")
var fname:String = "/Users/holyfield/Desktop/com.apple.IconComposer.plist"
var fm:NSFileManager = NSFileManager.defaultManager()
if(fm.fileExistsAtPath(fname)){
println("File Exists")
if(fm.isReadableFileAtPath(fname)){
println("File is readable")
var fd:NSData? = NSData(contentsOfFile: fname)
println(fd?.length)
let pl = NSDictionary(contentsOfFile: fname)
println(pl?.count)
println(pl?.allKeys)
}else{
println("File is not readable")
}
}
else{
println("File does not exists")
}

解决方法
我必须感谢Nate Cook的第一个快速反应和坚实的答案.
只是为了案例,我从另一篇文章中分享他的答案,哪个标题是误导的.
看到Nate在这里的答案：https://stackoverflow.com/a/26723557/2360439
Playgrounds are sandBoxed,so you won’t be able to just grab files from anywhere in your user folder. Here’s how to add that file to your
playground to make it accessible:
- Find your “.playground” file in the Finder Right click and choose “Show Package Contents”
- You should see “timeline.xctimeline”,“contents.xcplayground”,and “section-1.swift”
- Make a new folder called “Resources” if it doesn’t exists yet.
- Copy your files into Resources folder
似乎没有办法在Playground沙箱外使用Swift Playground访问文件.如果您知道如何访问沙箱外的文件,欢迎您分享您的解决方案！
