同时集成微信与企业微信，当点击分享到企业微信，点击分享调用代码：

WWKSendMessageReq *req = [[WWKSendMessageReq alloc] init];

    WWKMessageImageAttachment *attachment = [[WWKMessageImageAttachment alloc] init];

    attachment.filename = @"paper";

    attachment.path = self.path;

    req.attachment = attachment;

    [WWKApi sendReq:req];

打开的依然是微信客户端，而不是企业微信客户端；若项目不注册微信sdk，，则可正常使用企业微信分享
