FMDB结果集进入字典

Question

有没有一种简单的方法可以轻松地将FMDB结果executeQuery:SELECT * ...放入字典中？

FMResultSet *appointmentResults = [[DataClass getDB] executeQuery:@"SELECT * FROM Appointments WHERE date = ?",currDateString];
while ([appointmentResults next]) {
    //Create dictionary
    //Add dictionary to array for later use
}

我想知道是否有一种方法可以使字典键为列名,值为列值.优选地,不必在一段时间内遍历每一行.

是的:

NSMutableArray *results = [NSMutableArray array];

FMResultSet *appointmentResults = [[DataClass getDB] executeQuery:@"SELECT * FROM Appointments WHERE date = ?",currDateString];
while ([appointmentResults next]) {
  [results addObject:[appointmentResults resultDictionary]];
}

-resultDictionary是一个内置的方法FMResultSet,将当前元组转换为NSDictionary,由列名称键入.
