delegate = self
}
}
//2.跳转自动显示和隐藏TabBar

}
//4.这个代理方法的功能是哪个控制器进行展示了，也就是栈顶控制器

//5.这个方法看名称可以知道也是出栈，但是他出的非常彻底，直接回到了栈底，把栈里的子控制器都出栈了

}
return super.popToRootViewController(animated: animated)
}
//6.这个方法看多了个参数，也就说可以出栈到指定的控制器那个位置，就是指定的控制器之前的子控制器都得出栈。

if ((interactivePopGestureRecognizer?.responds(to: Selector(("interactivePopGestureRecognizer")))) != nil) && animated == true {
