Question

我有6个子类UIViewControllers与带有标识符的push segues连接。

＆lt; B＆gt; C＆gt; C＆gt; D＆gt; F＆gt; F。我无法找到如何在控制器A中实现按钮的方法，该按钮会自动将所有控制器堆叠到控制器F并显示F控制器。堆叠应该在UINavigationController实例中完成，而不是通过(void)setViewControllers:(NSArray *)viewControllers animated:(BOOL)animated，因为如果我使用setViewControllers方法，那么我将丢失segue标识符。 TY！

您应该可以使用pushViewController:animated:执行此操作，如下所示：

// This method belongs to view controller A class
-(void)pushToF {
    // I am assuming that A is already in the navigation controller
    UINavigationController *nav = self.navigationController;
    UIViewController *b =[self.storyboard instantiateViewControllerWithIdentifier:@"B"];
    [nav pushViewController:b animated:NO];
    UIViewController *c =[self.storyboard instantiateViewControllerWithIdentifier:@"C"];
    [nav pushViewController:c animated:NO];
    ... // And so on, until F
    UIViewController *f =[self.storyboard instantiateViewControllerWithIdentifier:@"F"];
    // You can push the last one with animation, so that end users would see it
    [nav pushViewController:f animated:YES];
}

在NavigationController中推送多个UIViewControllers
