Google Drive through iOS’s picker disable .apk and .ipa files.

When i attached files through iOS picker from google drive, at that time all files are shown or enable to me. But .apk and .ipa files are disable. So i can't choose them as my attachment.

Here is i attached my drive's screen shot.

and here is my code:

@try {

UIDocumentMenuViewController *viewController = [[UIDocumentMenuViewControlleralloc] initWithDocumentTypes:@[@"public.data"]inMode:UIDocumentPickerModeImport];

viewController.delegate = self;

viewController.popoverPresentationController.sourceView = [selfpopoverPresentationView];

viewController.popoverPresentationController.sourceRect = [selfpopoverPresentationRect];

viewController.popoverPresentationController.permittedArrowDirections = [selfpopoverPresentationArrowDirection];

[self.initialViewControllerpresentViewController:viewController animated:YEScompletion:nil];

} @catch (NSException *exception) {

[selfcancelWithAlertErrorText:NSLocalizedString(@"Can't load Document Picker", @"Error text")];

}

So, How can i enable this both of the files. Please anyone help..

Thanks in advance....!!
