使用融云SDK, 如何自定义好友消息。
融云sdk的集成方法可以访问 http://rongcloud.cn相关文档，下面介绍自定义好友消息的实现方法。
图1
图2
图1为自定义 viewController xo继承自 RCConversationListViewController 。 使用聚合的方式展示系统消息通知。
@interface SymtemViewController :RCConversationListViewController
@end
采用继承的方式，是为了重写点击cell的响应方式，接下来在.m 文件中重写父类的 onSelectedTableRow 方法。
//重载函数。
-(void)onSelectedTableRow:(RCConversationModelType)conversationModelType conversationModel:(RCConversationModel *)model atIndexPath:(NSIndexPath *)indexPath
{
if (model.conversationModelType ==RC_CONVERSATION_MODEL_TYPE_NORMAL) {
}
// 自定义type
elseif(model.conversationModelType ==RC_CONVERSATION_MODEL_TYPE_COLLECTION)
{
if (model.conversationType ==ConversationType_SYSTEM)
{
ChatListViewController *listVC = [[ChatListViewControlleralloc]init];
NSArray *array =@[[NSNumbernumberWithInt:ConversationType_SYSTEM]];
[listVC setDisplayConversationTypeArray:array];
[self.navigationControllerpushViewController:listVCanimated:YES];
}
}
//
elseif(model.conversationModelType ==RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION)
{
}
//
elseif(model.conversationModelType ==RC_CONVERSATION_MODEL_TYPE_PUBLIC_SERVICE)
{
NSLog(@” … SERVICE …”);
}
}
其中ChatListViewController为接下来要展示的好友的详细列表viewController。 继承自 RCConversationListViewController，在自定义cell之前先明确添加好友通知的几种情况。
其中
demo server 指 客户端服务器
RC server 指融云服务器
userID 指 当前用户ID
1 推荐好友。 如图2中sourceID_5。
当前只需要 demo server 向 RC server 发送好友推荐通知即可。
2 好友请求成功发送。 如图2中sourceID_6。
此时 demo server 需要调用两次接口，访问RC server两次。 第一次通知 userID 用户好友已发送。 第二次 向 sourceID_6 用户发送有一个好友请求。
3 对方同意你的好友请求。如图2中sourceID_7。
demo server 向 RC server 发送 userID 用户请求的状态。是第五条处理后发过来的结果。
4 收到好友请求。如图2中sourceID_8。
demo server 向 RC server 发送sourceID_8 向userID发送的好友请求。
5 处理好友请求。如图2中sourceID_9。
demo server 需要调用两次接口，访问RC server两次。 一次通知 userID 用户 结果。 另一次通知sourceID 用户操作结果。
如果不全，还可以通过修改发送内容，进行补充。
发送系统消息是通过调用如下API 来实现的。
发送系统消息 方法
说明：一个用户向一个或多个用户发送系统消息，会话类型为 SYSTEM。
方法名：/message/system/publish
调用频率：每秒钟限 100 次
签名方法：请参考 通用 API 接口签名规则
URL：https://api.cn.ronghub.com/message/system/publish.[format]
[format] 表示返回格式，可以为 json 或 xml，注意不要带 [ ]。
HTTP 方法：POST
表单参数
| 名称 | 类型 | 说明 |
|---|---|---|
fromUserId |
String | 发送人用户 Id。（必传） |
toUserId |
String | 接收用户Id，提供多个本参数可以实现向多用户发送系统消息，上限为 1000 人。（必传） |
objectName |
String | 消息类型，参考融云消息类型表.消息标志；可自定义消息类型。（必传） |
content |
String | 发送消息内容，参考融云消息类型表.示例说明；如果 objectName 为自定义消息类型，该参数可自定义格式。（必传） |
pushContent |
String | 定义显示的 Push 内容，如果为自定义消息，则为自定义消息显示的 Push 内容。(可选) |
pushData |
String | Push 通知附加的 payload 字段，字段名为 appData。(可选) |
其它不同的消息内空的区分是由objectName 和 content 来决定的。
好友通知objectName 固定为 @“RC:ContactNtf”。
content 内空实际上为一个字典 {“operation”:”Recommend”,”sourceUserId”:”5″,”targetUserId”:”1″,”message”:”haha”,”extra”:”hello extra”}
其它operation 对应的value值为操作内容。用于判断当前的通知是五种情况下下的一种。
当前sdk定义了三个已用宏
// 加好友请求。
#define ContactNotificationMessage_ContactOperationRequest @“Request”
// 同意好友请求。
#define ContactNotificationMessage_ContactOperationAcceptResponse @“AcceptResponse”
// 拒绝好友请求。
#define ContactNotificationMessage_ContactOperationRejectResponse @“RejectResponse”
// 推荐好友。
#define ContactNotificationMessage_ContactOperationRecommend @“Recommend”
// 加好友请求验证状态。
#define ContactNotificationMessage_ContactOperationRequestSent @“RequestSent”
需要注意一点
下面介绍自定义cell代码的实现。
在ChatListViewController.m 文件中
1 重写数据源的方法，设置好友通知消息为自定义类型
//
– (NSMutableArray *)willReloadTableData:(NSMutableArray *)dataSource
{
for (int i=0; i<dataSource.count; i++) {
RCConversationModel *model =[dataSource objectAtIndex:i];
if (model.conversationType ==ConversationType_SYSTEM
|| [model.lastestMessageisMemberOfClass:RCContactNotificationMessage.class]) {
model.conversationModelType =RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION;
}
}
return dataSource;
}
2 重写cell高度及cell加载方法。
//
– (CGFloat)rcConversationListTableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 80.0f;
}
//
– (RCConversationBaseCell *)rcConversationListTableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = @”cellidentifier”;
RCConversationModel *model = self.conversationListDataSource[indexPath.row];
id obj= model.lastestMessage;
if (![obj isKindOfClass:RCContactNotificationMessage.class])
{
// todo 处理其它类型的系统消息
return nil;
}
FriendMessageCell *cell = [[FriendMessageCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
[cell setFriendMessage:model];
return cell;
}
3 重写消息监听方法。
#pragma mark – 收到消息监听
-(void)didReceiveMessageNotification:(NSNotification *)notification
{
__weak typeof(&*self) blockSelf_ =self;
//处理好友请求
RCMessage *message = notification.object;
if ([message.contentisMemberOfClass:[RCContactNotificationMessageclass]])
{
RCContactNotificationMessage *msg = (RCContactNotificationMessage *)message.content;//
BOOL isExist = NO;
// 监测请求是否己存在
for (RCConversationModel *modelin self.conversationListDataSource) {
id obj= model.lastestMessage;
if (![objisKindOfClass:RCContactNotificationMessage.class]) {
continue;
}
RCContactNotificationMessage *notiMessage = (RCContactNotificationMessage *)obj;
// 判断sourceId targetUserId 均相同。例： 我可以同时向多个userID发送好友请求
if ([msg.sourceUserIdisEqualToString:notiMessage.sourceUserId] && [msg.targetUserIdisEqualToString:notiMessage.targetUserId]) {
isExist = YES;
break;
}
}
if (isExist == YES)
{
[blockSelf_ refreshConversationTableViewIfNeeded];
}
else
{
// dic 存储用户信息，cell中使用. 用户信息从demo server 获得。
NSDictionary *dic = [NSDictionarydictionary];
RCConversationModel *customModel = [[RCConversationModelalloc]init];
customModel.conversationModelType =RC_CONVERSATION_MODEL_TYPE_CUSTOMIZATION;
customModel.extend = dic;
customModel.senderUserId = message.senderUserId;
customModel.lastestMessage = msg;
customModel.sentTime = message.sentTime;
customModel.targetId = message.targetId;
//刷新
[blockSelf_ refreshConversationTableViewWithConversationModel:customModel];
}
[blockSelf_ resetConversationListBackgroundViewIfNeeded];
}else{
[superdidReceiveMessageNotification:notification];
}
}
…
全部代码如下：

-(void)onSelectedTableRow:(RCConversationModelType)conversationModelType conversationModel:(RCConversationModel *)model atIndexPath:(NSIndexPath *)indexPath
{
if (model.conversationModelType ==RC_CONVERSATION_MODEL_TYPE_NORMAL)
