消息内容检索

可以，调用我们的搜索的方法去搜索就行
/*!

* \~chinese

* 从数据库获取包含指定内容的消息，取到的消息按时间排序，如果参考的时间戳为负数，则从最新消息向前取，如果aCount小于等于0当作1处理

*

* @param aKeywords 搜索关键字，如果为空则忽略

* @param aTimestamp 参考时间戳

* @param aCount 获取的条数

* @param aSender 消息发送方，如果为空则忽略

* @param aDirection 消息搜索方向

* @param aCompletionBlock 完成的回调

*

* \~english

* Load messages with specified keyword, returning messages are sorted by receiving timestamp. If reference timestamp is negative, load from the latest messages; if message count is negative, count deal with 1 and load one message that meet the condition.

*

* @param aKeywords Search content, will ignore it if it's empty

* @param aTimestamp Reference timestamp

* @param aCount Count of messages to load

* @param aSender Message sender (optional)

* @param aDirection Message search direction

* @param aCompletionBlock The callback block of completion

*

- (void)loadMessagesWithKeyword:(NSString*)aKeyword

timestamp:(long long)aTimestamp

count:(int)aCount

fromUser:(NSString*)aSender

searchDirection:(EMMessageSearchDirection)aDirection

completion:(void (^)(NSArray *aMessages, EMError *aError))aCompletionBlock;这个方法

我参考demo里面的群组查找聊天记录
_conversation = [[EMClient sharedClient].chatManager getConversation:self.conversation type:EMConversationTypeChat createIfNotExist:NO];
在会话列表界面会话ID和会话类型这两个参数要怎么写
[self.conversation loadMessagesWithKeyword:searchBar.text timestamp:[self.datePicker.date timeIntervalSince1970]*1000 count:SEARCHMESSAGE_PAGE_SIZE fromUser:self.textField.text searchDirection:EMMessageSearchDirectionUp completion:^(NSArray *aMessages, EMError *aError) {

ConversationListController *strongSelf = weakSelf;

if (strongSelf) {

if([aMessages count]<SEARCHMESSAGE_PAGE_SIZE) {

strongSelf.hasMore = NO;

} else {

strongSelf.hasMore = YES;

}

[strongSelf.searchController.resultsSource removeAllObjects];

[strongSelf.searchController.resultsSource addObjectsFromArray:[[aMessages reverseObjectEnumerator] allObjects]];

[strongSelf.searchController.searchResultsTableView reloadData];

}

}];

会话ID 接收方的id 会话类型单聊或者群聊，聊天室

@柠檬不太酸

可是会话列表有很多不同id的会话，类型有单聊也有群聊怎么写

这个只能遍历去搜索了，没有其他的办法了

@柠檬不太酸

那环信这边有没有一个可以获取所有会话ID和类型的方法

@柠檬不太酸

这样遍历搜索后为什么只能搜索到会话列表第一条会话的消息内容 for(int i =0;i<self.conversationsArray.count;i++){

EMConversation * Conversation = self.conversationsArray[i];

self.conversation = [[EMClient sharedClient].chatManager getConversation:Conversation.conversationId type:Conversation.type createIfNotExist:NO];

__weak typeof(self) weakSelf = self;

[self.conversation loadMessagesWithKeyword:searchBar.text timestamp:[self.datePicker.date timeIntervalSince1970]*1000 count:SEARCHMESSAGE_PAGE_SIZE fromUser:self.textField.text searchDirection:EMMessageSearchDirectionUp completion:^(NSArray *aMessages, EMError *aError) {

ConversationListController *strongSelf = weakSelf;

if (strongSelf) {

if([aMessages count]<SEARCHMESSAGE_PAGE_SIZE) {

strongSelf.hasMore = NO;

}else {

strongSelf.hasMore = YES;

}

[strongSelf.searchController.resultsSource removeAllObjects];

[strongSelf.searchController.resultsSource addObjectsFromArray:[[aMessages reverseObjectEnumerator] allObjects]];

[strongSelf.searchController.searchResultsTableView reloadData];

}

}];

}

fromUser:传 nil 时间戳单位要求是毫秒，

@柠檬不太酸

搜索出结果后点击cell 怎么就崩了环信的demo也会崩

[已注销]

这个是群组搜索聊天记录崩溃吗

@柠檬不太酸

是的

[已注销]

在EaseMessageViewController.h中声明这个方法 - (NSArray *)formatMessages:(NSArray *)messages;
然后SearchChatViewController 在这个类 98行加上这段代码//MARK:搜索崩溃处理

[strongSelf.messsagesSource removeAllObjects];

[strongSelf.dataArray removeAllObjects];

NSArray *formattedMessages = [self formatMessages:aMessages];
