坑：
1.TXIMSDK_TUIKit_iOS中TContactViewModel字母分组的问题，如果好友信息和自己服务器管理的挂钩 那就直接拉取好友信息
/**
* 【模块名称】消息列表视图模型（TContactViewModel）
* 【功能说明】实现消息列表视图模型。
* 本视图模型负责从服务器拉取好友列表、好友请求并将相关数据加载。
* 同时本视图模型还会将好友按昵称首字母进行分组，从而帮助视图在界面右侧维护一个“字母表”方便快速检索好友。

2.在点击好友，进入聊天界面的时候，
不要直接获取会话，直接获取会创建一新的会话，
会话列表会都一条没有消息的会话。
应该在聊天界面判断会话列表是否有该会话，
再发送消息的时候没有会话再去获取
@interface ChatViewController : UIViewController
@property (strong, nonatomic) NSString *nickname;
@property (strong, nonatomic) NSString *convId;
@property (nonatomic, assign) TIMConversationType type;
@end
- (void)loadData {
self.navigationView.titleLabel.text = self.nickname;
if (self.type == TIM_GROUP) {
self.conv = [[TIMManager sharedInstance] getConversation:TIM_GROUP receiver:self.convId];
// 获取群信息
[self getGroupInfo];
// 获取消息
[self loadMessage];
}
else {
// [self.viewModel loadConversation];
for (TUIConversationCellData *data in self.viewModel.dataList) {
if ([data.convId isEqualToString:self.convId]) {
self.conv = [[TIMManager sharedInstance] getConversation:data.convType receiver:data.convId];
// 获取消息
[self loadMessage];
break;
}
}
}
}
