contentEdgeInsets was deprecated in iOS 15, now I am using self.configuration.contentInsets to set the padding of the button. But after I finished setting the configuration, I still need to call self.configuration.contentInsets.top/bottom/leading/trailing to calculate the intrinsicContentSize, but it is always return 0. The self.contentEdgeInsets.left/right/top/bottom works fine, but I do not want to use it since it is already deprecated, is there other solution?

You cannot alter the configuration through the property value (a pointer) which a UIButton already holds. Instead you should trigger a setter method, by settings configuration property as a whole:

UIButtonConfiguration *config = _mButton.configuration;
config.contentInsets = NSDirectionalEdgeInsetsMake(10, 10, 10, 10);
_mButton.configuration = config;
