iphone - Getting city and country from NSTimeZone

Question

I'd like to (at least) get the name of the country for a time zone. This is not provided by any of the potential methods:

• name,
• localizedName:locale:,
• description

I notice that the built in iPhone clock App has access to this information, as it describes London as "London, England".

Thanks.

Answer 1

我确信它与内置时钟不同。有一个城市数据库，每个城市都有一个国家和时区。你会期待[myGMT city]什么？都柏林还是卡萨布兰卡？

Answer 2

根据该timeZoneWithName:data:方法的描述，文件系统的时区信息位于/usr/share/zoneinfo.

我不知道文件的格式是什么，或者您是否甚至可以从应用程序沙箱中读取它们，但这可能是时钟应用程序获取信息的方式。
