能不能兼容 UIButton.Configuration 初始化的button

目前针对UIButton.Configuration 初始化的button 并不支持 但是也不会报错

Thanks for the report. We tested the current master with a button created using UIButton(configuration: .plain()) on an iOS 18.5 simulator. Calling the existing kf.setImage API successfully downloaded and displayed the image after layout, so we have not been able to reproduce the reported behavior yet.

One UIKit timing detail may be relevant: when Kingfisher's completion handler runs, button.image(for: .normal) is already set, but button.configuration?.image and button.imageView?.image may not be synchronized until a subsequent layout pass. A configurationUpdateHandler or later reassignment of button.configuration can also overwrite the downloaded image.

Could you provide:

• A minimal runnable example, including the configuration, button initialization, and kf.setImage call
• The Kingfisher, Xcode, and iOS/tvOS versions, and whether this occurs on a device or simulator
• The target control state and whether you are setting the foreground or background image
• Any configurationUpdateHandler, UIButton subclass, or later configuration assignment
• Whether the image remains absent after layout, or only configuration.image is nil inside the completion handler

That should help us distinguish an actual display issue from UIKit's delayed configuration synchronization.
