Navigation button

Last Updated: May 25, 2021

AUBarButtonItem in mPaaS is equivalent to UIBarButtonItem. It contains predefined items such as the color and font. To facilitate subsequent extension, AUBarButtonItem instead of UIBarButtonItem must be used in all mPaaS apps.

Currently, AUBarButtonItem completely is completely inherited from AUSwitch without any new properties or methods.
