objective-c - UISplitViewControllers detailView 中的 presentModalViewController 未全屏显示视图

Question

我在 mainViewControllers 视图中添加了 UISplitViewController 视图，代码如下。

    documentsRootViewController = [[DocumentsRootViewController alloc] initWithStyle:UITableViewStylePlain];
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:documentsRootViewController];
    documentsRootViewController.title = @"Document List";

    documentDetailView = [[DocumentsDetailView alloc] initWithNibName:@"DocumentsDetailView" bundle:nil];
    documentsRootViewController.detailViewController = documentDetailView;

    docSplitViewController = [[UISplitViewController alloc] init];
    docSplitViewController.viewControllers = [NSArray arrayWithObjects:navigationController, documentDetailView, nil];
    docSplitViewController.delegate = documentDetailView;

    CGRect splitViewFrame = CGRectMake(0, 0, cetralArea.frame.size.width, cetralArea.frame.size.height);         
    docSplitViewController.view.frame = splitViewFrame;
    [cetralArea addSubview:docSplitViewController.view];

现在我想要的是从 UISplitViewController 的 DetailView 中呈现一个 ViewController 我正在尝试在 DetailViewControllers 中按以下方式进行操作 Click Me！按钮单击。

- (IBAction) buttonClicked:(id)sender
{
    NSString *phrase = nil; // Document password (for unlocking most encrypted PDF files)    
    NSArray *pdfs = [[NSBundle mainBundle] pathsForResourcesOfType:@"pdf" inDirectory:nil];    
    NSString *filePath = [pdfs lastObject]; assert(filePath != nil); // Path to last PDF file

    ReaderDocument *readerDocument = [ReaderDocument withDocumentFilePath:filePath password:phrase];    
    if (readerDocument != nil) // Must have a valid ReaderDocument object in order to proceed with things
    {
        ReaderViewController *rViewController = [[ReaderViewController alloc] initWithReaderDocument:readerDocument];        
        rViewController.delegate = self; // Set the ReaderViewController delegate to self              

        [self presentModalViewController:rViewController animated:NO];        
    } 
}

但这导致了尴尬的演示

任何人都可以提出这里的问题，提前谢谢..

Answer 1

在您的屏幕截图中，我无法确定您的拆分视图控制器左侧和右侧（详细视图）位于何处。更改视图的背景颜色以区分位置。看来你和他们有问题。

无论如何，您可以尝试从 splitView 而不是 Detail 呈现模态视图控制器。

[splitViewController presentModalViewController:rViewController animated:NO];

Answer 2

我相信这里的技巧是改变你想要以模态方式显示的视图控制器的 modalPresentationStyle（以及可选的 modalTransitionStyle）：

    ReaderViewController *rViewController = [[ReaderViewController alloc] initWithReaderDocument:readerDocument];        
    rViewController.delegate = self; // Set the ReaderViewController delegate to self              

    rViewController.modalPresentationStyle = UIModalPresentationFullScreen;
    rViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;     
    [self presentViewController:rViewController animated:YES completion:nil];

Answer 3

我遇到了同样的问题（在 iOS 5.1 中）。将 modalPresentationStyle 设置为 UIModalPresentationPageSheet，它应该可以按预期工作。

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    rViewController.modalPresentationStyle = UIModalPresentationPageSheet;
    rViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
}

Answer 4

我发现你给出的 splitview 大小如cetralArea.frame.size.width.

而不是简单地直接给出你想给Splitview的大小。

希望它对你有用。
