如何将iOS应用程序中的联系人分享给Whatsapp？

Question

使用UIActivityViewController将.vcf共享给WhatsApp失败，显示插件net.whatsapp.WhatsApp.ShareExtension无效错误

使用UIActivityViewController共享图像或文本，但共享.vcf无法使用whatsapp（适用于邮件/消息/信使等）。

NSData *pVcfData     = [CNContactVCardSerialization dataWithContacts:[NSArray arrayWithObject:pContact] error:&pError]; // creating contact data from CNContactVCardSerialization

NSURL *pFileURL      = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:pFileNameWithAllowedCharacters]]; //  wrote the data to file

NSError *pWriteError = nil;

if ([pVcfData writeToURL:pFileURL options:NSDataWritingAtomic error:&pWriteError])
{
   NSArray *pActivityItems  =  @[pFileURL]; //  passed the file URL as ActivityItem for UIActivityViewController

   UIActivityViewController *pActivityVC = [[UIActivityViewController alloc] initWithActivityItems:pActivityItems applicationActivities:nil];

   [pActivityVC setValue:pContactName forKey:@"subject"];

   [self presentViewController:pActivityVC animated:YES completion:nil];
}

除了.vcf之外，还有其他方法可以与whatsapp共享联系吗？请分享任何建议。
