Question

以下代码适用于ipad，但不适用于iphone。

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
UIViewController *controller = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:@"MoreAppsViewController"];

UINavigationController *navgiate = [[UINavigationController alloc]initWithRootViewController:controller];

[self.navigationController pushViewController:navgiate animated:YES];

我无法通过安装来加载MoreApsviewController。 View Controller没有推动请帮我怎么做。在此先感谢

Answer 1

如果您的容器是导航控制器，您可以简单地使用VC并像这样推送它;

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
    UIViewController *controller = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:@"MoreAppsViewController"];
    //No need to create a nav controller here
    [self.navigationController pushViewController:controller animated:YES];

如果您想添加另一个导航控制器，您可以将其显示或添加为子VC，但是您无法推送另一个导航VC。

应检查这两个步骤。

如果您尝试访问的View Controller嵌入在导航控制器中，则引用正确的视图是正确的，否则，请将UINavigationController *navgiate更改为UIViewController * navigate（或者如果UITableViewController *导航，则这是一个表格视图。
检查视图控制器的引用。如果您的名称为(UIViewController *)[storyboard instantiateViewControllerWithIdentifier:@"MoreAppsViewController"];，我将假设您已将视图控制器命名为MoreAppsViewController。您需要将UINavigationController命名为 并引用 ，因为它是参考点。

这是View Controller的结果：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
UIViewController *controller = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:@"MoreAppsViewController"];

[self.navigationController pushViewController:controller animated:YES];

这是导航控制器的结果：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
//You need to name your Navigation Controller "MoreAppsViewController" for this to work
UINavigationController *controller = (UINavigationController *)[storyboard instantiateViewControllerWithIdentifier:@"MoreAppsViewController"];
[self.navigationController pushViewController:controller animated:YES];

pushviewcontroller在xcode6中不起作用
