Quickblox iOS - 比較自定義對象請求中的日期

Question

我試圖對我的對象請求執行自定義過濾器，它將返回在最後一小時內創建的所有對象。但是，以下不起作用：

NSMutableDictionary *getRequest = [NSMutableDictionary dictionary]; 
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
    // Show vehicles based on the user's selected radius (add filter) 

    NSInteger radius = 500 * 1.6 * 1000; 
    NSDate *minusOneHr = [[NSDate date] dateByAddingTimeInterval:-60*60]; 

    [getRequest setObject:[NSString stringWithFormat:@"%f,%f;%li",[[prefs objectForKey:@"longitude"] floatValue],[[prefs objectForKey:@"latitude"] floatValue], (long)radius] forKey:@"alertLocation[near]"]; 

    [getRequest setObject:[NSDate date] forKey:@"created_at[gt]"]; 
    [getRequest setObject:minusOneHr forKey:@"created_at[lt]"]; 

    [QBRequest objectsWithClassName:@"Alerts" extendedRequest:getRequest successBlock:^(QBResponse *response, NSArray *objects, QBResponsePage *page) { 

     [[self.tabBarController.tabBar.items objectAtIndex:2] setBadgeValue:[NSString stringWithFormat:@"%lu", (unsigned long)objects.count]]; 

    } errorBlock:^(QBResponse *response) { 

     NSLog(@"error: %@", response.error); 
     // 
    }]; 

任何人都知道是否可以在created_at日期使用gt和lt運算符？

Answer 1

您正在爲擴展請求設置錯誤的字段名稱。 正確的字段名稱是：

• _id *
• created_at *
• 的updated_at *
• USER_ID *
• _parent_id *
