swift - 在 swift 2 中使用 imagePickerController

Question

我正在使用以下函数从用户照片库中抓取照片，但出现错误:

Objective-C method 'imagePickerController:didFinishPickingImage:editinginfo conflicts with optional requirement in protocol UIImagePickerControllerDelegate.

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {

    print("Image Selected")

    self.dismissViewControllerAnimated(true, completion: nil)

    importedImage.image = image

}

谁能告诉我如何修改函数以符合 swift 2.0 可选要求？

谢谢!

Answer 1

swift 2.0 版本:

    func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
        // you code
    }

如果您使用 XCode 7，您只需删除此函数，然后重新键入它并允许 XCode 使用新语法自动完成它。

注意，此协议(protocol)要求已被弃用，请改用此协议(protocol):

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        // your code
    }
