多设备


其他端登录的设备ID

当PC端和手机端登录同一个账号时,在手机端可以通过特定方法获取到PC端的设备ID,该设备ID相当于特殊的好友Username,可以直接使用于聊天,使用方法与好友类似。

- (void)getSelfIdsOnOtherPlatformWithCompletion:(void (^)(NSArray *aList, EMError *aError))aCompletionBlock;

使用示例

NSArray *otherPlatformIds = [[EMClient sharedClient].contactManager getSelfIdsOnOtherPlatformWithError:nil];
if ([otherPlatformIds count] > 0) {
    NSString *chatter = otherPlatformIds[0];
    //获取会话
    EMConversation *conversation = [[EMClient sharedClient].chatManager getConversation:chatter type:EMConversationTypeChat createIfNotExist:YES];
    
    //发送消息
    NSString *sendText = @"test";
    EMTextMessageBody *body = [[EMTextMessageBody alloc] initWithText:sendText];
    NSString *from = [[EMClient sharedClient] currentUsername];
    EMMessage *message = [[EMMessage alloc] initWithConversationID:conversation.conversationId from:from to:chatter body:body ext:nil];
    message.chatType = EMChatTypeChat;
    [[EMClient sharedClient].chatManager sendMessage:message progress:nil completion:nil];
}

多设备事件回调

账号A同时在设备A和设备B上登录,账号A在设备A上进行一些操作,设备B上会收到这些操作对应的通知,具体说明如下:

接口 EMMultiDevicesDelegate

/*!
 *  多设备事件类型
 *  用户UserA,登录2台机子DeviceA1和DeviceA2,另有一个用户UserB
 */
