（客服云）iOS访客端点击订单消息

1、在HDMessageCell.m 的
- (void)_setupSubviewsWithType:(EMMessageBodyType)messageType
                      isSender:(BOOL)isSender
                         model:(id)model
方法中给orderBgView 添加手势

UITapGestureRecognizer *tapRecognizer3 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(orderImageViewTapAction:)];
[_bubbleView.orderBgView addGestureRecognizer:tapRecognizer3];

 
2、在HDMessageCell.m 中添加手势点击事件

- (void)orderImageViewTapAction:(UITapGestureRecognizer *)tapRecognizer

{

    if ([_delegate respondsToSelector:@selector(messageCellSelected:)]) {
[_delegate messageCellSelected:_model];

    }

}

 
3、在HDMessageViewController的 
   - (void)messageCellSelected:(id)model 方法中添加订单消息的判断

代码：

if ([HDMessageHelper getMessageExtType:model.message] == HDExtOrderMsg) {

    // 订单消息携带的扩展

    NSDictionary *dic = model.message.ext;

    NSLog(@"点击了订单消息");

}
