--iOS-OC-自定义融云IM聊天界面，键盘收回去输入工具栏下去

我开始做了一个APP，聊天界面，上面是几个固定的，类似于新浪微博的消息界面，上面是固定的，下面是会话列表

1.自己写一个会话列表继承RCConversationListViewController；

2.设置会话类型；（这里我就不详细说了，融云教学视频很详细，下面才是最重要的，自定义会话列表）

3.出入自己的数据源数据，父类里面有个设置数据源的方法；记住一定要设置conversationModelType的类型为：RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION（用户自定义的会话显示），然后我设置置顶显示 model.isTop = YES;

//插入自定义会话model
- (NSMutableArray *)willReloadTableData:(NSMutableArray *)dataSource{
    if ([PersonInfo.type isEqualToString:@"STUDY"]) {
        _titleArr = @[@"系统通知",@"评论",@"点赞"];
    }else if ([PersonInfo.type isEqualToString:@"TEACHER"]){
        _titleArr = @[@"系统通知",@"评论",@"点赞",@"访客"];
    }
    for (int i = 0; i<_titleArr.count; i++) {
        RCConversationModel *model = [[RCConversationModel alloc]init];
        model.conversationModelType = RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION;
        model.conversationTitle = _titleArr[i];
        model.isTop = YES;
        [dataSource insertObject:model atIndex:i];
    }
    return dataSource;
}

4.设置cell的高度

#pragma mark - 设置cell的高度
- (CGFloat)rcConversationListTableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return 70;
}

5.关闭cell的左滑删除事件；因为头部几个点击是跳转新的控制器，是固定的，不能删除；

#pragma mark - 设置cell的删除事件
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    RCConversationModel *model = [self.conversationListDataSource objectAtIndex:indexPath.row];
    if(model.conversationModelType == RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION){
        return UITableViewCellEditingStyleNone;
    }else{
        return UITableViewCellEditingStyleDelete;
    }
}

6.修改cell上面字体的字体样式；RCConversationBaseCell里面没有title和content label等控件，所以需要转化一下；转成RCConversationCell；我用的是平方字体；

#pragma mark - 修改cell样式
- (void)willDisplayConversationTableCell:(RCConversationBaseCell *)cell atIndexPath:(NSIndexPath *)indexPath{
    RCConversationModel *model = [self.conversationListDataSource objectAtIndex:indexPath.row];
    if(model.conversationModelType != RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION){
        RCConversationCell *RCcell = (RCConversationCell *)cell;
        RCcell.conversationTitle.font = [UIFont fontWithName:@"PingFangSC-Light" size:18];
        RCcell.messageContentLabel.font = [UIFont fontWithName:@"PingFangSC-Light" size:16];
        RCcell.messageCreatedTimeLabel.font = [UIFont fontWithName:@"PingFangSC-Light" size:14];
    }
}

7.自定义cell，注意自定义的cell一定要继承于RCConversationBaseCell

#pragma mark - 自定义cell
- (RCConversationBaseCell *)rcConversationListTableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    RongYunListCell *cell = [tableView dequeueReusableCellWithIdentifier:@"RongYunListCell"];
    if (!cell) {
        cell = [[[NSBundle mainBundle]loadNibNamed:@"RongYunListCell" owner:self options:nil] firstObject];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        cell.ListOneCount.hidden = YES;
    }
    NSInteger count = 0;
    if(indexPath.row < _badgeValueArr.count){
        count = [_badgeValueArr[indexPath.row] integerValue];
    }
    if(count>0){
        cell.ListOneCount.hidden = NO;
        cell.ListOneCount.text = [NSString stringWithFormat:@"%ld",count];
    }else{
        cell.ListOneCount.hidden = YES;
    }
    RCConversationModel *model = self.conversationListDataSource[indexPath.row];
    [cell setRongYunListCellOneUIViewWithModel:model iconName:_iconArr[indexPath.row]];
    return cell;
}

8.cell的选中事件

#pragma mark - cell选中事件
- (void)onSelectedTableRow:(RCConversationModelType)conversationModelType conversationModel:(RCConversationModel *)model atIndexPath:(NSIndexPath *)indexPath{
    [self.conversationListTableView deselectRowAtIndexPath:indexPath animated:YES];
    if(model.conversationModelType == RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION){
        NSString *cellTitle = model.conversationTitle;
        if([cellTitle isEqualToString:@"系统通知"]){
            //系统消息
            NewsSystemSecondViewController *svc = [[NewsSystemSecondViewController alloc]init];
            svc.hidesBottomBarWhenPushed = YES;
            [self.navigationController pushViewController:svc animated:YES];
        }else if ([cellTitle isEqualToString:@"评论"]){
            //评论
            SystemCommentViewController *svc = [[SystemCommentViewController alloc]init];
            svc.hidesBottomBarWhenPushed = YES;
            [self.navigationController pushViewController:svc animated:YES];
        }else if ([cellTitle isEqualToString:@"点赞"]){
            //点赞
            ClickLinckedViewController *svc = [[ClickLinckedViewController alloc]init];
            svc.hidesBottomBarWhenPushed = YES;
            [self.navigationController pushViewController:svc animated:YES];
        }else if ([cellTitle isEqualToString:@"访客"]){
            //访客
            MyVistorsViewController *svc = [[MyVistorsViewController alloc]init];
            svc.hidesBottomBarWhenPushed = YES;
            [self.navigationController pushViewController:svc animated:YES];
        }
    }else{
        //会话列表
        RCConversationViewController *conversationVC = [[RCConversationViewController alloc]init];
        conversationVC.hidesBottomBarWhenPushed = YES;
        conversationVC.conversationType = model.conversationType;
        conversationVC.targetId = model.targetId;
        conversationVC.title = [self getUserNameWithUserID:model.targetId];
        [self.navigationController pushViewController:conversationVC animated:YES];
    }
}
