pop返回指定页面

不废话, 直接上代码!!!!!

第一种：

let viewController = self.navigationController?.viewControllers[2]

self.navigationController?.popToViewController(viewController!, animated: true)

第二种：

let nsVC = NSActiveViewController()

for  vc : UIViewController in (self.navigationController?.viewControllers)! {

if vc.isKindOfClass(nsVC.classForCoder) {

LTLog("返回女神controller")

self.navigationController?.popToViewController(vc, animated: true)

}

}
