UIImagePickerController：didFinishPickingMediaWithInfo没有被调用

Question

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不能和我一起玩...

我将代码分为以下几部分，以便允许我从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. 工作：加载ImagePickerViewController并启用选择图像
4. 失败：添加了附加功能，用于关闭和完成UIImagePicker的拾取，但是都没有被调用？我做错了什么？

提前致谢！

    uploadImage(image)

好的，我现在似乎可以正常运行了，感谢您的帮助，以确认代码是古老的；）现在运行的是：

    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!)
}

您的签名错误，但由于它是一种可选方法，因此您不会收到警告。它应该是：

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