1.分享

1.导入sdk
2.配置

sdk（友盟的和第三方平台）放进去。添加一系列的框架。注意：要加imageIO框架。把flags 设置为－Objc，否则在注册微博时crash啊crash

3.注册

//注册友盟和微信等
[UMSocialData setAppKey:@"5603d3c967e58e5f4c001593"];
//没客户端隐藏
[UMSocialConfig hiddenNotInstallPlatforms:@[UMShareToWechatSession, UMShareToWechatTimeline]];

4.点击分享（友盟的view）

//举例分享到微信，qq
//分享成功提示文字在窗口的上方，可以修改
  [UMSocialConfig setFinishToastIsHidden:NO position:UMSocialiToastPositionCenter];

//title  正标题
     [UMSocialData defaultData].extConfig.wechatTimelineData.title = SHARE_TITLE;
     [UMSocialData defaultData].extConfig.wechatSessionData.title = SHARE_TITLE;
     [UMSocialData defaultData].extConfig.qqData.title = SHARE_TITLE;
     [UMSocialData defaultData].extConfig.qzoneData.title = SHARE_TITLE;
    //微信／朋友圈 QQ url 分享后点击图片或者文字链接到网页地址 新浪不用设置
     [UMSocialData defaultData].extConfig.wechatSessionData.url = STRAWBERRY_URL;
     [UMSocialData defaultData].extConfig.wechatTimelineData.url = STRAWBERRY_URL;
     [UMSocialData defaultData].extConfig.qqData.url = STRAWBERRY_URL;
     [UMSocialData defaultData].extConfig.qzoneData.url = STRAWBERRY_URL;



   NSString *shareText=[NSString stringWithFormat:@"品名:草莓（约800g）产地:上海 规格:800g/箱 包装: 保质期:2天 存储条件:冷藏"];／／副标题
            
            NSArray *arr=@[UMShareToQQ,UMShareToWechatTimeline,UMShareToWechatSession,UMShareToSina,UMShareToTencent,UMShareToSms,UMShareToRenren];
           
 
            [UMSocialSnsService presentSnsIconSheetView:self appKey:nil shareText:shareText shareImage:[UIImage imageWithData:data] shareToSnsNames:arr delegate:nil];

//通常分享的图片是网络的,而要传入的是image或NSData对象，所以用ImageView 的sd_set来做

  UIImageView *sharImage = [[UIImageView alloc]init];
  [sharImage sd_setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",MSMImageApi,self.model.default_pic]] completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
    //这里可以拿到Image，从而进行上面的操作。
    //注意：这里不要直接用image，最好用sharImage.image,因为用Image时sharImage已经释放了。用杀人sharImage.image则block对sharImage有个抢引用，不会释放。可能你会认为会造成循环引用，其实不然，这里的block不是sharImage 的实例变量，不会造成循环引用的
