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

共享图像或文本正在使用UIActivityViewController工作,但共享.vcf不适用于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.

根据文档https://www.whatsapp.com/faq/en/iphone/23559013，将文件格式设置为 .wai 并将 UTI 设置为 net.whatsapp.image 只会在应用程序列表中显示 Whatsapp，

但它显示了其他应用程序，如添加到笔记，信使也与 whatsapp 选项一起。

    if let imageData = UIImageJPEGRepresentation(image, 1.0)
    { 
        let path = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
        let documentsDir: AnyObject = path[0]
        let imagePath = documentsDir.stringByAppendingPathComponent("Main")

        NSFileManager.defaultManager().createDirectoryAtPath(imagePath, withIntermediateDirectories: true, attributes: nil)

        let tempFile = NSURL(fileURLWithPath: imagePath+"/image.wai")
        do
        {
            try imageData.writeToURL(tempFile, options: .DataWritingAtomic)
            self.documentController = UIDocumentInteractionController(URL: tempFile)
            self.documentController.UTI = "net.whatsapp.image"
            self.documentController.presentOpenInMenuFromRect(self.view.frame, inView: self.view, animated: true)
        }
        catch
        {
            // alert

        }
    }

请建议我是否在这里做错了什么
