导航控制器内部跳转

写项目中遇到导航控制器内不相邻两个界面的跳转，都是以RootViewController为父类，想跳转到RenZhengViewController里面，代码如下：

RootViewController *target =
nil;

for (RootViewController * controller
in self.navigationController.viewControllers) {
//遍历

if ([controller
isKindOfClass:[RenZhengViewController
class]]) { //这里判断是否为你想要跳转的页面

target = controller;

}

}

if (target) {

[self.navigationController
popToViewController:target
animated:YES];
//跳转

}
