iOS从不同页面跳转回到指定控制器

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

    }        

如果知道是第几级界面，则用如下方法

UIViewController *viewCtl = self.navigationController.viewControllers[2];

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