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 sand@R_301_460@ed,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！
