Buttons not visible in UIDocumentPickerViewController

Question

I want to import a document into my application. I have created a Demo to import Document. A demo is working. below is the code of the Demo to open UIDocumentPickerViewController.

-(IBAction) btnOpenClicked{
    UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:[self allowedUTIs] inMode:UIDocumentPickerModeImport];
    documentPicker.delegate = self;

    [self presentViewController:documentPicker animated:true completion:nil];
}

-(NSArray*)allowedUTIs{
    return @[@"public.data",@"public.content",@"public.audiovisual-content",@"public.movie",@"public.audiovisual-content",@"public.video",@"public.audio",@"public.text",@"public.data",@"public.zip-archive",@"com.pkware.zip-archive",@"public.composite-content",@"public.text"];
}

The same code is implemented in my actual project. UIDocumentPickerViewController open and App is able to import file but the issue is that in the actual app I am not able to see any buttons in the header. thought there is action happen but buttons are not visible. Please check screenshot of the Demo and actual app.

Your app is probably setting a global UINavigationBar tint color appearance. You can just reset the appearance for UIDocumentPickerViewController only by putting this code somewhere in your application:didFinishLaunchingWithOptions: function and the bar buttons will return to their original blue.

if #available(iOS 11.0, *) {
    UINavigationBar.appearance(whenContainedInInstancesOf: [UIDocumentBrowserViewController.self]).tintColor = nil
}

Can this not be done on iOS 10? I am trying to do the same but with instance of UIDocumentPickerViewController, but that doesn't seem to do anything? – lindanordstrom Jun 26 '18 at 07:58
Not sure about iOS 10, maybe try to inspect the view controller hierarchy to see which one contain the navigation items using a tool like Reveal. – Antoine Lamy Jun 27 '18 at 13:03
Hm, no, doesn't give me any more information. Thanks though! – lindanordstrom Jun 28 '18 at 14:37

For Objective C:

-> by putting this code somewhere in your application:didFinishLaunchingWithOptions:

[[UINavigationBar 
    appearanceWhenContainedInInstancesOfClasses:
      @[[UIDocumentBrowserViewController class]]] setTintColor: nil];
