最近一段时间,开了一个新项目,涉及到即时聊天.对接的融云,也是踩了无数个坑.在这里总结一下,供大家参考.
如果你也遇到了问题.欢迎留言,自我感觉也是踩完大部分坑了.
一.注册融云 下载并接入SDK
这个其实没啥说的, https://www.rongcloud.cn/docs/ios.html 官方链接,可以帮你完成基本的接入及使用问题.
二.信息提供者
这是最坑的地方,也是融云核心所在. 涉及到的东西有点多,可能会说的有点乱.
先看官方说法:
融云认为，每一个设计良好且功能健全的 App 都应该能够在本地获取、缓存并在合适的时机更新 App 中的用户信息。所以，融云不维护和管理用户基本信息（用户ID、昵称、头像）的获取、缓存、变更和同步。
核心模式解答:
官方的意思就是说,我不保存头像和昵称这些信息. 我只有对话信息. app服务器(自己的接口)和融云都有聊天对象的id,用id来识别.完成整个数据的拼接组合.而这个过程的入口,就是信息提供者的几个方法.
我贴一下我的实现代码.和实现逻辑. 为了完成单聊和群聊.这几个代理都实现了.
1.在AppDelegate初始化融云,并创建信息提供者单例类,CTRongManager.
- (void)initRongClound:(UIApplication *)application{
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
//融云
[[RCIM sharedRCIM] initWithAppKey:key_rongyun];
//设置用户信息提供者为 [RCDataManager shareManager]
[RCIM sharedRCIM].userInfoDataSource = [CTRongManager shareManager];
//设置群组信息提供者为 [RCDataManager shareManager]
[RCIM sharedRCIM].groupInfoDataSource = [CTRongManager shareManager];
//群成员数据源
[RCIM sharedRCIM].groupMemberDataSource = [CTRongManager shareManager];
//群成员名片
[RCIM sharedRCIM].groupUserInfoDataSource = [CTRongManager shareManager];;
//头像设置
[RCIM sharedRCIM].portraitImageViewCornerRadius = 15;
//开启消息@功能（只支持群聊和讨论组, App需要实现群成员数据源groupMemberDataSource）
[RCIM sharedRCIM].enableMessageMentioned = YES;
//开启消息撤回功能
[RCIM sharedRCIM].enableMessageRecall = YES;
//开启用户信息和群组信息的持久化
[RCIM sharedRCIM].enablePersistentUserInfoCache = YES;
//SDK中全局的导航按钮字体颜色
[RCIM sharedRCIM].globalNavigationBarTintColor = [UIColor blackColor];
//关闭声音
[RCIM sharedRCIM].disableMessageAlertSound = YES;
[RCIM sharedRCIM].receiveMessageDelegate = self;
/**
* 推送处理1
*/
if ([application
respondsToSelector:@selector(registerUserNotificationSettings:)]) {
//注册推送, 用于iOS8以及iOS8之后的系统
UIUserNotificationSettings *settings = [UIUserNotificationSettings
settingsForTypes:(UIUserNotificationTypeBadge |
UIUserNotificationTypeSound |
UIUserNotificationTypeAlert)
categories:nil];
[application registerUserNotificationSettings:settings];
} else {
//注册推送，用于iOS8之前的系统
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound;
[application registerForRemoteNotificationTypes:myTypes];
}
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(didReceiveMessageNotification:)
name:RCKitDispatchMessageNotification
object:nil];
}
我们开启了很多功能 用不到的话,可以不开启.
下面是核心代码,CTRongManager单例类.
CTRongManager.h

上面就是各种信息提供者的各种实现,有几点需要注意
1.实现代理要遵守代理.别忘了
[RCIM sharedRCIM].userInfoDataSource = self;
[RCIM sharedRCIM].groupInfoDataSource = self;
[RCIM sharedRCIM].groupUserInfoDataSource = self;
[RCIM sharedRCIM].groupMemberDataSource = self;
2.实现的代理就是信息提供者.实现的思路是:首先去数据库取(因为链接融云之后 我们进行了数据请求,获取到了部分用户数据并存入了数据库,数据库创建下面会提到),取不到的话就请求接口(这里就需要一个可以获取任何人信息的接口,用来补充数据.)
三.数据库的创建
fmdb的使用,主要存储用户和群组信息

这就是用户信息的存储,这是必要的.不可能所有的信息每次都请求接口.
基本上都这么写,没啥好说的.
四:通知推送.
首先你要知道本地通知和远程推送.在程序进入后台一段时间后,app被杀死. 才进入远程推送.推送的开启和关闭,我这边最后的结果是这样做的.
首先进入app,默认关闭推送声音,
//关闭声音
[RCIM sharedRCIM].disableMessageAlertSound = YES;
然后在设置里面给一个开关,这个开关没有那么详细.就是开启或者关闭推送和通知.只要你关闭了,无论是推送还是通知统统收不到.
-(void)totalSwitchClick:(UISwitch *)swiftch{
[SVProgressHUD show];
if (swiftch.on) {
[[RCIMClient sharedRCIMClient] setNotificationQuietHours:@"00:00:00"
spanMins:1439
success:^{
[SVProgressHUD dismiss];
[CTUserInfor shareUser].isOpenMessage = @"1";
}
error:^(RCErrorCode status) {
[SVProgressHUD dismiss];
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
message:@"设置失败"
delegate:nil
cancelButtonTitle:@"取消"
otherButtonTitles:nil, nil];
[alert show];
swiftch.on = NO;
});
}];
} else {
[[RCIMClient sharedRCIMClient] removeNotificationQuietHours:^{
[SVProgressHUD dismiss];
[CTUserInfor shareUser].isOpenMessage = @"0";
}
error:^(RCErrorCode status) {
[SVProgressHUD dismiss];
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
message:@"取消失败"
delegate:nil
cancelButtonTitle:@"取消"
otherButtonTitles:nil, nil];
[alert show];
swiftch.on = YES;
});
}];
}
}
剩下的就是一些ui的自定制什么的了.
整体来说,融云还是蛮难接的.
