objective-c - 将 NavigationController 添加到当前 View

Question

我正在使用 UIScrollView 来显示一些图像，当用户选择图像的一部分时，我需要呈现或推送另一个 View 。此 ScrollView 仅以编程方式创建。我如何以编程方式向其添加 navigationController 并呈现另一个 View ？

我试过这种方式，但只给我以下错误:

Pushing a navigation controller is not supported'

 StatesViewController * controller = [[StatesViewController alloc]initWithNibName:@"StatesViewController" bundle:nil];

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

    [self presentModalViewController: Navcontroller animated: YES];

Answer 1

这可能对你有帮助。

 NextViewController *nextViewController=[[NextViewController alloc]initWithNibName:@"NextViewController" bundle:nil];
    UINavigationController *navBar=[[UINavigationController alloc]initWithRootViewController:nextViewController];
    [self.navigationController presentModalViewController:navBar animated:YES];
