That functionality is not built-in to UIImagebecause images are not always loaded from files. However, you could create a custom UIImageViewsubclass to fit your needs.
该功能不是内置的，UIImage因为图像并不总是从文件加载。但是，您可以创建自定义UIImageView子类以满足您的需要。

It is not possible. UIImage instance contains the actual image data without any reference to the filename.
这不可能。UIImage 实例包含实际的图像数据，没有对文件名的任何引用。

Images do not necessarily come from files or other named sources, so not all images even have a name. When you create an image from a file, you could store the name in a separate NSString*, and then refer to that stored name when necessary.
图像不一定来自文件或其他命名来源，因此并非所有图像都有名称。当您从文件创建图像时，您可以将名称存储在单独的 中NSString*，然后在必要时引用该存储的名称。
