3.0 中的核心类为 EMClient 类,通过 EMClient 类可以获取到 chatManager、groupManager、contactManager、roomManager对象。原来 2.0 版本的 SDK 很多方法提供了同步、异步回调、异步(block)三种方法,3.0 版只提供同步方法和异步block方法。
例如:
//2.0版本登录方法,提供了同步、异步、异步block三种方法
- (NSDictionary *)loginWithUsername:(NSString *)username
password:(NSString *)password
error:(EMError **)pError;
- (void)asyncLoginWithUsername:(NSString *)username
password:(NSString *)password;
- (void)asyncLoginWithUsername:(NSString *)username
password:(NSString *)password
completion:(void (^)(NSDictionary *loginInfo, EMError *error))completion
onQueue:(dispatch_queue_t)aQueue;
//3.0版本,网络请求的方法提供了同步方法和异步block方法
- (EMError *)loginWithUsername:(NSString *)aUsername
password:(NSString *)aPassword;
- (void)loginWithUsername:(NSString *)aUsername
password:(NSString *)aPassword
completion:(void (^)(NSString *aUsername, EMError *aError))aCompletionBlock;
注册回调,3.0 SDK 对功能进行了模块化,将不同功能回调封装到不同模块。
//2.0版本回调注册
[[EaseMob sharedInstance].chatManager addDelegate:self delegateQueue:nil];
//3.0版本回调注册需要分模块注册
[[EMClient sharedClient] addDelegate:self delegateQueue:nil];//登录相关的回调
[[EMClient sharedClient].groupManager addDelegate:self delegateQueue:nil];//群组回调
[[EMClient sharedClient].contactManager addDelegate:self delegateQueue:nil];//联系人回调
[[EMClient sharedClient].roomManager addDelegate:self delegateQueue:nil];//聊天室回调
[[EMClient sharedClient].chatManager addDelegate:self delegateQueue:nil];//消息回调
3.0 SDK 大部分代码与 2.0 SDK 比较,逻辑没有变化,为了统一修改了名称。
入口的变化,2.0 版本 [EaseMob shareInstance] → 3.0 版本 [EMClient sharedClient]。
