更改UIDocumentInteractionController导航栏的颜色

Question

有没有办法改变色调/背景颜色UIDocumentInteractionController navigationbar？

Answer 1

@DOOManics实现的更清洁版本:

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
    return [self navigationController];
}

Answer 2

如果将 UIDocumentInteractionController 放到 UINavigationController 上，它将自动采用其导航栏的颜色。这可能是您的根视图导航控制器。

您可以使用以下方法执行此documentInteractionControllerViewControllerForPreview操作：

- (UIViewController *) documentInteractionControllerViewControllerForPreview: (UIDocumentInteractionController *) controller
{
    // Use the rootViewController here so that the preview is pushed onto the navbar stack
    MyAppDelegate *appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
    return appDelegate.window.rootViewController;
}
