I have implemented UIDocumentMenuViewController in my application with below code
_importMenu = [[UIDocumentMenuViewController alloc] initWithDocumentTypes:[MingleUtils allowedUTIs] inMode:UIDocumentPickerModeImport];
_importMenu.delegate = self;
[self presentViewController:_importMenu animated:YES completion:nil];
It is working but picker is taking time to appear and sometimes getting error "couldnt comunicate with helper application" Can anyone help me in this?
