从无索引的 NASArrray 提取对象
原标题:Extract object from NSArray without an index

我有一个 NSmubableAray 被调用的结果, 以这种格式显示以下对象:

Contents of results  : {(
    (0x073BCE60) EAN13: 0710425390128 -- (0 finds)
)}

我需要从中提取 0710425390128 但是没有指数......我不知道如何实现这一点。

Is there away to modify the NSMutableArray to add an index? Or is there a method to determine an index of sorts for this item (if that makes any sense)?

我希望提取的项目在每次创建结果时都会有所不同 。

谢谢 谢谢


我试图用 id objects Instance 从数组结果中创建 NSDigitary

NSUInteger indexKey = 0; 
NSMutableDictionary *mutableDictionary = [[NSMutableDictionary alloc] init]; 
for (objectInstance in results) {
    [mutableDictionary setObject:objectInstance forKey:[NSNumber numberWithUnsignedInt:indexKey++]]; 
}

将数据格式格式化为

{ "Scanned Items" = ( "(0x0733A120) EAN13: 0710425390128 -- (0 finds)" ); "Session End Time" = "2012-05-25 01:23:55 +0000"; } 

仍然丢失了如何指定值密钥 。

问题回答

使用 NSdictionary 。使用 keys ,您可以检索 object 。请参看

我不知道您的意思是 : “ 是否有时间修改 Mudiable 矩阵以添加索引”

在给定索引使用时访问数组中的对象:

[myArray objectAtIndex: someIndex];
