'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'

Answer 1

The message "Pushing a navigation controller is not supported" is the hint. 提示“不支持按下导航控制器”。 Check your storyboard, if you are really using a "modal" presentation of the new view controller, or if you are accidently using the "push" operation, wich will only work for common view controllers. 如果您确实在使用新的视图控制器的“模态”演示文稿，或者您不小心使用了“推”操作，请检查情节提要，仅对普通视图控制器有效。 Push may not work for Navigation Controllers. 推送可能不适用于导航控制器。
