UIImagePickerController：没有调用 didFinishPickingMediaWithInfo

希望你们一切都好。想知道是否有人可以帮助我理解为什么 Xcode 不能很好地配合我......

我已将代码分为以下几个部分，以便我可以从 UIImagePicker 中选择个人资料照片：

1. 作品：为 ImagePicker 和 NavigationController 分配委托类
2. 作品：实例化 UIImagePicker 变量
3. 作品：加载 ImagePickerViewController 并启用选择图像
4. 失败：添加了用于关闭和完成 UIImagePicker 选取的附加功能，但都没有被调用？我做错了什么？

提前致谢！

class ProfileVC: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
var imagePicker: UIImagePickerController!

override func viewDidLoad() {
    super.viewDidLoad()

    imagePicker = UIImagePickerController()
    imagePicker.delegate = self
}

@IBAction func selectPhotoPressed(sender: UITapGestureRecognizer) {
    if UIImagePickerController.isSourceTypeAvailable(.PhotoLibrary) {
        self.imagePicker.sourceType = .PhotoLibrary
    } else {
        self.imagePicker.sourceType = .Camera
    }
    imagePicker.allowsEditing = true
    imagePicker.mediaTypes = [kUTTypeImage as String]
    self.presentViewController(imagePicker, animated: true, completion: nil)
}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    self.dismissViewControllerAnimated(true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo image: UIImage, editingInfo: [String : AnyObject]?) {
    headerView.profilePhoto.contentMode = .ScaleAspectFill
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image)
}

好的，我现在似乎可以正常工作了，感谢您帮助识别代码是古老的；）这是现在运行的内容：

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as? UIImage
    headerView.profilePhoto.contentMode = .ScaleAspectFit
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image!)
}
