我正在开发一个 ipad 应用程序，我使用了一个标签栏作为 rootViewController，在每个标签内我都有 splitviewControllers。现在，我以这种方式在单击按钮时呈现 ModalView

- (void)someFunction
{

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
        {
            AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
           TestViewController *test = [[TestViewController alloc]initWithNibName:@"TestViewController" bundle:nil];
            moveNote.modalPresentationStyle = UIModalPresentationFormSheet;

            [appDelegate.splitViewController2 presentModalViewController:test animated:YES];
            test.view.superview.bounds = CGRectMake(0, 0, 540, 350);//Dimensions of ModalView.
         }

}

我通过 SplitviewController 呈现 ModalView。

现在这可以正确打开。现在在这里面我有一个按钮，点击它我想关闭这个 ModalView 并呈现另一个 ModalView。为此，我编写了以下代码

- (void)closeTest
{
[self dismissViewControllerAnimated:YES
                                 completion:^{


                                     EditViewController *editViewController = [[EditViewController alloc] initWithNibName:@"EditViewController" bundle:nil];
                                     editViewController.modalPresentationStyle = UIModalPresentationFormSheet;

                                     [appDelegate.splitViewController2 presentModalViewController:editViewController animated:YES];
                                     editViewController.view.superview.bounds = CGRectMake(0, 0, 540, 350);//Dimensions of ModalView.
                                     editViewController.page = 3;              


                                     //Call delegate function.
                                 }];      
    }
}

但这不起作用，我的应用程序崩溃了。

我在这里做错了什么？
