FMDB 直接将查询结果转化为字典

 1 NSString *querySql = @"select * from stuInfo";
 2     
 3     NSMutableArray *arr = [[NSMutableArray alloc] init];
 4     
 5     FMResultSet *result = [_database executeQuery:querySql];
 6 
 7     while ([result next]) {
 8         //用数组arr保存一条记录转成的字典
 9         [arr addObject:[result resultDictionary]];
10     }
11     
12     NSLog(@"arr:%@", arr);
