presentModalViewController不显示工具栏？

Question

我有一个viewcontroller我试图显示为UIModalPresentationFormSheet,但它没有显示其UIToolbar.如何在其上显示工具栏？

ConnectionEditViewController * connectionEditViewController = [[ConnectionEditViewController alloc] initWithNibName:@"ConnectionEditViewController" bundle: nil];
connectionEditViewController.modalInPopover = YES;
connectionEditViewController.modalPresentationStyle = UIModalPresentationFormSheet;
connectionEditViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self presentModalViewController: connectionEditViewController animated: YES];

Answer 1

创建一个UINavigationController实例,将rootViewController设置为您的connectionEditViewController,然后配置UINavigationController的模态属性并显示它.

如果这是在iPad上,它应该弹出视图,导航栏作为顶部的灰色工具栏.配置connectionEditViewController的navigationItem以配置导航栏.
