//创建分享消息对象

UMSocialMessageObject*messageObject =[UMSocialMessageObject messageObject];

//设置文本

messageObject.text =@"社会化组件UShare将各大社交平台接入您的应用，快速武装App。";

//创建图片内容对象

UMShareImageObject*shareObject =[[UMShareImageObject alloc] init];

//如果有缩略图，则设置缩略图

shareObject.thumbImage =[UIImage imageNamed:@"icon"];

[shareObject setShareImage:@"https://www.umeng.com/img/index/demo/1104.4b2f7dfe614bea70eea4c6071c72d7f5.jpg"];

//分享消息对象设置分享内容对象

messageObject.shareObject = shareObject;

//调用分享接口

[[UMSocialManager defaultManager] shareToPlatform:platformType messageObject:messageObject currentViewController:self completion:^(id data,NSError*error){
