iPod Touch第二代 - 固件

[英]iPod Touch Second Generation - firmware

原文 2010-11-10 18:08:51 4 1 iphone/ ios/ ipod

I am updating an app that initially was compatible with iOS 2.0 and up. 我正在更新一个最初与iOS 2.0及更高版本兼容的应用程序。

As Apple dropped support for releases < 3.0, I am being forced to drop support for 2.0. 由于Apple放弃了对3.0版本的支持，我不得不放弃对2.0的支持。

Some beta testers using iPod Touch second generation are complaining the software is not running well. 一些使用iPod Touch第二代的测试人员抱怨软件运行不佳。 These guys report their iPod Touch 2nd Gen to be model A1228. 这些人报告他们的iPod Touch第二代型号为A1228。 The app runs perfectly on iPhone 3G, 3GS and 4. 该应用程序可以在iPhone 3G，3GS和4上完美运行。

The app does not use any function that is not present on iPod Touch 2nd gen. 该应用程序不使用iPod Touch第二代产品不具备的任何功能。

I suppose it can be a firmware problem on the iPod Touch 2nd Gen. The guys may be using an old release or never updated. 我想这可能是iPod Touch第二代的固件问题。这些人可能正在使用旧版本或从未更新过。

My question is: what firmware version came with iPod Touch 2nd gen and what is the latest firmware version available for this device? 我的问题是：iPod Touch 2nd gen附带了什么固件版本以及该设备可用的最新固件版本是什么？ 3.1.3? 3.1.3？

thanks. 谢谢。

I'm not sure what the first firmware was, but you can get iOS 4.1 for iPod touch 2nd genereation, and if you are a developer, iOS 4.2 as well. 我不确定第一个固件是什么，但是您可以得到适用于iPod touch第二代的iOS 4.1，如果您是开发人员，也可以使用iOS 4.2。

You can get information about the device using the UIDevice class. 您可以使用UIDevice类获取有关设备的信息。 To get the version information, use the systemVersion property, which will return a NSString. 要获取版本信息，请使用systemVersion属性，该属性将返回NSString。

EDIT: 编辑：

According to this website , the first iOS version was 2.1.1. 根据这个网站，第一个iOS版本是2.1.1。 You can also download all of the iOS firmwares there. 您还可以下载所有iOS固件。
