推荐答案

为什么您无法将所选的第一个选项卡移动到最左侧的位置，是否有特定原因?

Is there a specific reason why you can't move your chosen first tab to be presented to the left most slot?

self.tabBarController.selectedIndex = desiredIndex

或者，如果您的代码在 UITabBarConroller 子类中，只需:

or, if you're code is in a UITabBarConroller subclass, simply:

 selectedIndex = desiredIndex

应该可以.
