如何使用新的Xcode制作iPhone OS 2.1项目?
问题:我想制作iPhone OS 2.1应用程序，但是Xcode现在总是自动制作一个iPhone OS 3.0项目.我忘了它，现在我有一个要在iPod touch上测试的应用程序，但是我需要构建OS 2.1.有办法使它工作吗?
Problem: I want to make iPhone OS 2.1 apps, but Xcode now always makes automatically an iPhone OS 3.0 project. I forgot about it and now I have an app which I want to test on my iPod touch, but I need to build OS 2.1. Is there a way to get this working?
Xcode左上方的下拉菜单仅提供针对OS 3.0设备的构建.但是，当我打开旧项目时，就有可用的OS 2.1.
The dropdown from top left in Xcode only offers to build for OS 3.0 device. However, when I open old projects, there I have OS 2.1 available.
