stringByAppendingPathComponent不可用

Question

我正在为Swift 2更新我的代码，而且我遇到了我在本地为用户配置文件保存的图像文件路径问题。 我不知道在哪里解决这个问题，我尝试过使用URLByAppendPathComponent，但我不确定我错过了什么

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
    self.dismissViewControllerAnimated(true, completion: { () -> Void in
    })

    profileImageView.image = image

    let fileManager = NSFileManager.defaultManager()

    var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] 

    var filePathToWrite = "\(paths)/profileImage.jpeg"

    var imageData : NSData = UIImageJPEGRepresentation(image, 1.0)!

    fileManager.createFileAtPath(filePathToWrite, contents: imageData, attributes: nil)

    let imageFile : PFFile = PFFile(name: "profileImage.jpeg", data: imageData)
    imageFile.save()

    let getImagePath = paths.stringByAppendingPathComponent("profileImage.jpeg")
    print("getImagepath: \(getImagePath)")

    let user = PFUser.currentUser()
    user.setObject(imageFile, forKey: "profileImage")
    user.saveEventually()
}

如果有人可以帮我弄清楚如何在这里更新我的代码，我将不胜感激！

谢谢！

Answer 1

let nsPath = Path as! NSString

现在NSPath拥有你想要的所有功能 - 在swift2.0中它们有点禁用隐式转换

Answer 2

嘿，我有同样的问题..我改变.stringByAppendingPathComponent("profileImage.jpeg")与.stringByAppendingString("/profileImage.jpeg") ..

这里重要的是forwardslash / 。

Answer 3

替换它

var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] 

同

let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as! String
