ios - 使用 UIDocumentInteractionController 时隐藏状态栏？

Question

我正在开发一个需要查看/共享 PDF 文件的 React Native 应用程序。我正在使用 react-native-open-file使用 UIDocumentInteractionController 查看 PDF 文件的模块。打开 PDF 文件时，状态栏会出现在 PDF 上方。我的应用程序始终隐藏状态栏。如何在查看 PDF 时隐藏状态栏？

Here's the code from the module :

#import "RNDocumentInteractionController.h"
#import <UIKit/UIKit.h>

@implementation RNDocumentInteractionController

RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(open: (NSURL *)path)
{
    UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL:path];
    interactionController.delegate = self;
    [interactionController presentPreviewAnimated:YES];
}

- (UIViewController *) documentInteractionControllerViewControllerForPreview: (UIDocumentInteractionController *) controller
{
    return [[[[UIApplication sharedApplication] delegate] window] rootViewController];
}


@end

我能够添加一个 documentInteractionControllerDidEndPreview 方法，它在关闭后隐藏状态，但我宁愿永远不要打开状态栏:

- (void)documentInteractionControllerDidEndPreview:(UIDocumentInteractionController *)controller
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

我认为下面的代码应该可以:

- (UIViewController *) documentInteractionControllerViewControllerForPreview: (UIDocumentInteractionController *) controller
{
    [[[[UIApplication sharedApplication] delegate] window] setWindowLevel:UIWindowLevelStatusBar];

    return [[[[UIApplication sharedApplication] delegate] window] rootViewController];
}
