UINavigationController---pop到指定c

方法一:

//指定要pop到的控制器层级
UIViewController *viewCtl = self.navigationController.viewControllers[2];

    [self.navigationController popToViewController:viewCtl animated:YES];

方法二:

HomeViewController *homeVC = [[HomeViewController alloc] init]; 
UIViewController *target = nil; 
for (UIViewController * controller in self.navigationController.viewControllers) { //遍历 
if ([controller isKindOfClass:[homeVC 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 
}
