发送轨迹消息，显示不出消息的具体内容

问题描述

解决方案

发送轨迹消息，如果用户想显示body的具体内容，可以在desc里面展示。对于轨迹消息，我们现在只解析扩展消息里面的内容，其他的信息不做展示的。
解决方案二：
-(void)sendTextMessage:(NSString *)textMessage{    NSDictionary *ext = @{@"msgtype":@{                                  //用户轨迹消息                                  @"track":@{                                          // 消息标题                                          @"title":@"我正在看：",                                          // 商品价格                                          @"price":@"¥: 235.00",                                          // 商品描述                                          @"desc”:textMessage,                                          // 商品图片链接                                          @"img_url":@"http://pic14.nipic.com/2011052 ... ot%3B,                                          // 商品页面链接                                          @"item_url":@"http://www.nipic.com/show/3/15 ... ot%3B                                          }                                      }                          };          EMMessage *tempMessage = [ChatSendHelper sendTextMessageWithString:textMessage                                                            toUsername:_conversation.chatter                                                           messageType:[self messageType]                                                     requireEncryption:NO                                                                   ext:ext];    [self addMessage:tempMessage];} 代码举例如上。
