iOS微信分享

集成微信sdk，可以使用

    pod 'WechatOpenSDK'

初始化sdk

  BOOL result = [WXApi registerApp:KWXAPPID universalLink:KWXUniversalLinks];
  if (result == NO) {
        NSLog(@"registerApp:KWXAPPID == %d",result);
    }

使用微信sdk，注册成功后可以分享多媒体消息和文本消息

    SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
//发送多媒体消息
    req.bText = NO;
  /*
 WXSceneSession          = 0,  < 聊天界面  
    WXSceneTimeline         = 1,   < 朋友圈    
    WXSceneFavorite         = 2,   < 收藏      
    WXSceneSpecifiedSession = 3,   < 指定联系人
    WXSceneState            = 4,  < 状态  
  */
    req.scene = WXSceneSession;

  //生成多媒体消息内容
  WXMediaMessage *message = [WXMediaMessage message];

    // 标题
    message.title = @"标题";

    // 描述
    message.description = @"描述";

    // 缩略图
    [message setThumbImage:[UIImage imageNamed:@"imagename"]];

    WXWebpageObject *webPageObject = [WXWebpageObject object];

    webPageObject.webpageUrl = @"https://www.baidu.com";

    message.mediaObject = webPageObject;

    req.message = message;

  //发送消息
  [WXApi sendReq:req completion:^(BOOL success) {
        DLog(@"分享成功。%d",success);
    }];
