无法将文件从捆绑复制到iOS中的文档目录

Question

let bundlePath = NSBundle.mainBundle().pathForResource("information", ofType: ".png")
print(bundlePath, "\n") //prints the correct path
let destPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first!
let fileManager = NSFileManager.defaultManager()
let fullDestPath = NSURL(fileURLWithPath: destPath).URLByAppendingPathComponent("information.png")
let fullDestPathString = String(fullDestPath)
print(fileManager.fileExistsAtPath(bundlePath!)) // prints true

do{
try fileManager.copyItemAtPath(bundlePath!, toPath: fullDestPathString)
}catch{
    print("\n")
    print(error)
}

Answer 1

问题就出在这一行：

let fullDestPathString = String(fullDestPath)

应该是：

let fullDestPathString = fullDestPath.path

看看这个错误。问题是目的地。请注意文件：///。您的代码无法正确地将URL转换为文件路径。您需要使用nsurl的path属性以字符串形式获取路径。
