【问题描述】：

您好，我是 iOS 开发新手，请给我一个解决方案，从 UIView 导航到 UIViewController：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];

我也试过下面的代码来推送视图控制器，但这也不起作用，请帮我解决这个问题：

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

【解决方案1】：

请在您的故事板中添加导航控制器。

step -1: select acceptedJobDetailViewController from storyboard.
step -2: now go to Editor>EmbedIn>NavigationController
step -3: now below code and run your project


acceptedJobDetailViewController *acceptedJobDetailViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"acceptedJobDetailViewController"];

【解决方案2】：

如果您已经在您的storyboard 中添加了NavigationController，并且您尝试从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];

如果您还没有导航，请将其添加到您的 ViewController 之前，如下所示

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

现在添加到故事板中的导航控制器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。

【解决方案3】：

试试这个

[[(UIViewController *)[self.superview nextResponder] navigationController] pushViewController:"your viewcontroller object" animated:NO];

更新到 swift 3

(superview?.next? as? UIViewController)?.navigationController?.pushViewController("your viewcontroller object", animated: false)
