iPod touch 与 iPhone 4 作为开发平台的比较（iOS 4.1）
我想修改一个老问题，关于在 iPod touch 上开发应用程序作为 iPhone 的廉价替代品：
iPod Touch 与 iPhone 作为 iPhone 应用程序开发平台的比较
现在 Apple 发布了配备 Retina 显示屏的新款 iPod touch 和 iPhone 4，两者均搭载 iOS 4.1.
我是否应该选择新的 iPod touch 而不是 iPhone 4 作为开发设备？当然，除了电话功能之外，我还会遇到哪些差异？
I would like to revamp an old question, concerning the development of apps on the iPod touch as a cheap replacement for the iPhone:
iPod Touch compared to iPhone as development platform for iPhone apps
Now Apple has released the new iPod touch with Retina display and the iPhone 4, both with iOS 4.1.
Should I choose the new iPod touch as a development device instead of the iPhone 4, which differences would I encouter, apart from the phone feature of course?

只有当您的应用程序以其他方式使用它们时，差异才会很明显：
与 iPhone 4 相比，新的 iPod Touch：
由于大多数应用程序不使用相机或 GPS，因此这可能不是什么大问题。视网膜显示差异也很小（根据我所读到的）。最可能让您感到悲伤的差异是 RAM 的大小，特别是如果您正在制作游戏，但由于您谈论的是在 iPod Touch 而不是 iPhone 4 上进行开发，因此您可能是安全的，因为什么可以使用当有更多可用内存时，更少的内存应该可以工作。
The differences are only substantial if your app would otherwise make use of them:
Compared to the iPhone 4, the new iPod Touch:
Since most apps don't use the camera or the GPS, that's probably not a big deal. The retina display difference is also pretty minor (from what I've read). The difference most likely to give you grief is the amount of RAM, especially if you are making a game, but since you're talking about developing on the iPod Touch and not the iPhone 4, you're probably safe, since what works with less RAM should work when there's more RAM available.
通常，区别在于手机具有更多功能。 GPS、电话和指南针 IIRC。如果您计划制作一款同时适用于 Touch 和 Phone 的应用程序，那么就不会有什么区别。如果您打算使用电话，请使用电话。
Typically the difference is the phone has more features. GPS, phone, and compass IIRC. If you plan on making an app that is both for the Touch and Phone, then there wouldn't be a difference. If you plan on taking advantage of the phone, go for the phone.
iPod touch 是一款出色的开发设备。比 iPhone 便宜并且容易获得。现在第四代也更接近iPhone。
The iPod touch is an excellent development device. Less expensive than an iPhone and easy to get. And now with the fourth generation also much closer to the iPhone.
