如何在 iPad 中将 UIModalPresentationFormSheet 与 NavigationController 一起使用？

Question

我想在我的应用程序中使用 UIModalPresentationFormSheet。但我正在使用导航控制器。因此，当我编写以下代码时，它没有响应我。我该怎么办？

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

Answer 1

试试这样的：

 // assume controller is UIViewController.
 controller.modalPresentationStyle = UIModalPresentationFormSheet;

然后

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

Answer 2

检查以下示例工作代码。

MyModalViewController *targetController = [[[MyModalViewController alloc] init] autorelease]; 

targetController.modalPresentationStyle = UIModalPresentationFormSheet;
targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; //transition shouldn't matter 
[self presentModalViewController:targetController animated:YES];

targetController.view.superview.frame = CGRectMake(0, 0, 200, 200);//it's important to do this after 

presentModalViewController targetController.view.superview.center = self.view.center;
