QuickBlox API group_by在CustomObject上查詢

Question

我想檢索所有customObjects的最新日期group_by user_id。 如何在IOS中提出此請求？

Answer 1

嘗試這樣的事情

NSMutableDictionary *getRequest = [NSMutableDictionary dictionary]; 
[getRequest setObject:@"user_id" forKey:@"group_by"]; 
[getRequest setObject:@"max" forKey:@"created_at[calc]"]; 

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