我正在构建一个通用的iOS应用程序,iPad版本使用SplitViewController.在popover视图中,我有一个带有两个按钮的UITabBarController.当它在iPhone上运行时,TabBar按钮正确拉伸以填充视图的整个宽度......

...但是在iPad上,在弹出视图中,按钮不会伸展以填满整个宽度......

我正在以编程方式创建UITabBarController ...

InspectionTabBarViewController *inspectionTabBarVC;
    InspectionListViewController *inspectionListVC;
