我正在尝试获取从Swift中的Library导入的图像的URL以将其发送到Apple Watch,transferFile(_:metadata)但我有两个错误NSURL.

这是我的代码:

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!)
{
    imagePicked.image = image    
    let imageUrl = editingInfo[UIImagePickerControllerReferenceURL] as! NSURL
    let imageName = imageUrl.path!.lastPathComponent
    let documentDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as String!
    let localPath = documentDirectory.stringByAppendingPathComponent(imageName)
    let image = editingInfo[UIImagePickerControllerOriginalImage]as! UIImage
    let data = UIImagePNGRepresentation(image)

    data!.writeToFile(localPath, atomically: true)

    let photoURL = NSURL(fileURLWithPath: localPath)

    self.dismissViewControllerAnimated(true, completion: nil);
}

我在使用*imageName和*localPath时遇到错误,因为它说:

'lastPathComponent'不可用:改为使用NSURL上的lastPathComponent.'stringByAppendingPathComponent'不可用:改为在NSURL上使用URLByAppendingPathComponent.

但我无法在Swift 2.0和Xcode 7中做到正确.我哪里出错了？
