我想从我的核心数据实体中获取偶数和奇数值,请查看下面的代码并更正,因为它崩溃了应用程序.

        NSPredicate *predicate;
        if ([leadFilter.rank isEqualToString:@"Even"]) {
            predicate = [NSPredicate predicateWithFormat:@"(street%2) = 0"];
        }
        else
            predicate = [NSPredicate predicateWithFormat:@"street%2 != 0)"];
        [predicateArray addObject:predicate];

它的说法无法解析街道%2 = 0.
