ios - 如何从 UIView 导航 UIViewController

Question

您好，我是 iOS 开发新手，请给我一个从 UIView 导航到 UIViewController 的解决方案:这是我使用过的代码，但它不起作用

acceptedJobDetailViewController *acceptedJobDetailViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"acceptedJobDetailViewController"];
[self.navigationController pushViewController:acceptedJobDetailViewController animated:YES];

我还尝试了下面的代码来推送 View Controller ，但这也不起作用，请帮我解决这个问题:

[appDelegate.navControl pushViewController:acceptedJobDetailViewController animated:YES];

如果您已经在 storyboard 中添加了 NavigationController 并且您正尝试从 UIView 类推送屏幕而不是使用以下代码:

UIViewController *superViewController =  (UIViewController*)[self nextResponder];
UINavigationController *navigationController = superViewController.navigationController;
[navigationController pushViewController:<YOUR_VIEW_CONTROLLER_OBJECT> animated:YES];

如果你还没有和任何导航请像下面一样在你的 ViewController 之前添加它

Select ViewController -> Go to Editor Menu -> Embed In -> Navigation Controller

现在 Navigation Controller 添加到您的 Storyboard中，现在可以执行您之前正在执行的操作。

acceptedJobDetailViewController *acceptedJobDetailViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"acceptedJobDetailViewController"];
[self.navigationController pushViewController:acceptedJobDetailViewController animated:YES];

希望这会有所帮助。
