检索存储在自定义表 quickblox 中的聊天消息

Question

我将用户聊天消息存储在自定义表中。我希望检索两个用户之间的消息。现在我正在使用以下代码

NSNumber *user_id, *user2_id;
...
//chatMessages = [dict valueForKey:@"items"];
NSMutableDictionary *getRequest = [NSMutableDictionary dictionary];
[getRequest setObject:@"created_at" forKey:@"sort_asc"];
[getRequest setObject:[NSArray arrayWithObjects:user_id,user2_id, nil] forKey:@"user_id[in]"];
[getRequest setObject:[NSArray arrayWithObjects:user2_id,user_id, nil] forKey:@"receiver_id[in]"];

[QBCustomObjects objectsWithClassName:@"Chat" extendedRequest:getRequest delegate:self];

但这会检索到一些奇怪的结果。在 SQL 中我会尝试

WHERE (user_id='firstUser' AND receiver_id='anotherUser') or (user_id='anotherUser' AND receiver_id='firstUser')

但我不明白如何向 QuickBlox 提出同样的问题。

Answer 1

你可以尝试下一个getRequest：

 NSMutableDictionary *getRequest = [NSMutableDictionary dictionary];  
 [getRequest setObject:@"created_at" forKey:@"sort_asc"];
 NSArray *users = @[@(2000), @(1992)];
 [getRequest setObject:users forKey:@"receiver[in]"];  
 [getRequest setObject:users forKey:@"sender[in]"];
 [QBCustomObjects objectsWithClassName:@"Chat" extendedRequest:getRequest delegate:self];

在这种情况下，我会收到 id 为 2000 和 1992 的用户之间的所有消息

UPD: 现在看来是正确的。 （尝试在getRequest中传递相同用户的id数组）
