iOS 推出指定的UIViewController
UINavigationController 提供的常用接口是push和pop，但都是操作最顶层的页面 topViewController，若要操作指定的页面，可以访问属性 viewControllers @implementation UINavigationController(zlAddition) - (void)zl_popTheViewController:(UIViewController *)viewController animated:(BOOL)animated { if (viewController.navigationController == self) { if (self.topViewController == viewController) { [self popViewControllerAnimated:animated]; } else { NSMutableArray *arr = [self.viewControllers mutableCopy]; if (arr.lastObject != viewController) { [arr removeObject:viewController]; [self setViewControllers:arr animated:animated]; } } } } @end
