如何使用NSTimeZone -timeZoneWithName：来自Rails ActiveSupport的城市名称？ [英] How to use NSTimeZone -timeZoneWithName: with a city name from Rails ActiveSupport?

问题描述

如果我只有 Bangkok 或 Tokyo 这样的城市名称，我如何在
中提供时区参数[NSTimeZone timeZoneWithName ：@亚洲/东京] 在城市前面还有大陆和斜线？

If I only have the city name like Bangkok or Tokyo, how can I supply a timezone parameter in [NSTimeZone timeZoneWithName:@"Asia/Tokyo"] where it also has continent and slash in front of city?

我已经尝试过 [NSTimeZone timeZoneWithName：@Tokyo] ，它不起作用。

I already tried [NSTimeZone timeZoneWithName:@"Tokyo"], it doesn't work.

推荐答案

谢谢对于答案人员，但看起来这些城市名称只是RailsActiveSupport :: TimeZone使用的格式。所以我只需要将它映射回来。映射在这里 - > http://api.rubyonrails.org/classes/ActiveSupport/TimeZone .html

Thanks for the answers guys, but it looks like those city names are just a format that Rails "ActiveSupport::TimeZone" uses. So I just have to map it back. The mapping is here -> http://api.rubyonrails.org/classes/ActiveSupport/TimeZone.html

它将RailsActiveSupport :: TimeZone格式的时区映射到iOS使用的另一种格式（例如International Date Line West=> Pacific / Midway，Midway Island=>Pacific / Midway，Samoa=>Pacific / Pago_Pago，...）。

It maps the timezone from Rails "ActiveSupport::TimeZone" format to another format that iOS uses (e.g. "International Date Line West" => "Pacific/Midway", "Midway Island" => "Pacific/Midway", "Samoa" => "Pacific/Pago_Pago", ... ).

I已创建 plist文件，其中包含可轻松用于映射的NSDictionary属性。

I have created a plist file containing a NSDictionary property that can easily be used for mapping.
