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
*/

EMMultiDevicesEventGroupUnBlock = 24, // UserA在DeviceA1上取消了屏蔽GroupA的消息，DeviceA2会收到该回调
EMMultiDevicesEventGroupAssignOwner = 25, // UserA在DeviceA1上更新了GroupA的群主，DeviceA2会收到该回调
EMMultiDevicesEventGroupAddAdmin = 26, // UserA在DeviceA1上添加了GroupA的管理员，DeviceA2会收到该回调
EMMultiDevicesEventGroupRemoveAdmin = 27, // UserA在DeviceA1上移除了GroupA的管理员，DeviceA2会收到该回调
EMMultiDevicesEventGroupAddMute = 28, // UserA在DeviceA1上禁言了GroupA的某些成员，DeviceA2会收到该回调
EMMultiDevicesEventGroupRemoveMute = 29, // UserA在DeviceA1上移除了GroupA的某些禁言成员，DeviceA2会收到该回调
