我很难将数据结构添加到数组中以从循环中创建字典数组.我只知道NSMutableArray中的addObject只添加指向它的指针.我想知道如何实现我的目标.

这是我的代码:

NSMutableDictionary *woRows = [[NSMutableDictionary alloc] init];
NSMutableArray *workOrders = [[NSMutableArray alloc] init];
while ([theScanner isAtEnd] == NO)
{
    if ([theScanner scanUpToCharactersFromSet:usSet intoString:&tempCol1] &&
        [theScanner scanString:@"{US}" intoString:NULL] &&
        [theScanner scanUpToCharactersFromSet:usSet intoString:&tempCol2] &&
        [theScanner scanString:@"{US}" intoString:NULL] &&
        [theScanner scanUpToCharactersFromSet:usSet intoString:&tempCol3]&&
        [theScanner scanString:@"{RS}" intoString:NULL])
    {
        [woRows  setValue:tempCol1 forKey:@"hours"];
        [woRows setValue:tempCol2 forKey:@"colMain"];
        [woRows setValue:tempCol3 forKey:@"colAddtl"];

        [workOrders addObject:woRows];
        [woRows release];
    }
}
[tmpString release];
[jobs addObject:workOrders];
[workOrders release];

从上面的代码中,数组workOrders将只添加最后一个对象的副本.我坚持到这里无法进展以显示正确的数据.

任何帮助将不胜感激.

谢谢
