我们何时以及如何开始忘记非视网膜显示屏 iPhone 和 iPod Touch？
距离视网膜显示设备出现已经一年多了。有谁知道有多少用户仍然在低分辨率设备下受苦？他们使用 iPhone 或 iPod 多久后才意识到视网膜显示屏要好得多？
我厌倦了必须创建每个图形两次，用所有这些低分辨率文件丢弃二进制文件。我想知道是否有人停止支持低分辨率硬件而没有造成重大损失。
并且：如果我想停止支持低分辨率设备，我必须在 info.plist 中进行什么样的设置？如果低分辨率设备仍然安装我的仅视网膜应用程序，会发生什么？
Now more than one year passed since a retina display device appeared. Does anyone know some numbers how many users still suffer under the low-resolution devices? How long do they use their iPhones or iPods until they realize that a retina display is so much better?
I'm sick of having to create every graphic two times, trashing the binary with all these low-resolution files. I wonder if anyone has stopped supporting low resolution hardware without a big loss.
And: If I wanted to stop supporting low resolution devices, what kind of settings in the info.plist must I make? And what would happen if a low-res device still installs my retina-only app?

为什么人们仍然使用 IE 6？或者为什么有些人仍然使用 Windows XP？只是因为他们买不起新的。钱是罪魁祸首。至于何时应该停止支持某些技术，没有简单的答案。在技术领域，您通常应该等待大公司（例如 Facebook）停止支持某些设备。只有那些大鲨鱼才能迫使人们转变。
如果您希望您的用户满意并希望您的软件很棒，您应该尽可能支持所有可用的设备/版本。对您而言，很少的工作对您的用户来说却是一大好处。
最后，你不必做任何你不想做的事情。但你的软件会类似它。
Why do people still use IE 6? or why do some people still have Windows XP? Simply b/c they can't afford new ones. Money is to blame. There is no simple answer as to when should you stop supporting certain technology. In the technology world you should usually wait for a big company (like Facebook) to stop supporting certain devices. Only those big sharks can force people to switch.
If you want your users to be happy and want your software to be great you should always support all available devices/versions if possible. Little work for you is a big benefit for your users.
In the end you don't have to do anything you don't want to. But your software will resemble it.
您至少可以等待Apple停止为低分辨率设备（即iPhone 3G S）提供iOS更新，因为它能够运行iOS 5
You can at least wait for Apple to stop providing iOS updates to low-resolution devices (i.e. iPhone 3G S) since it is capable of running iOS 5
也许现在不可能，因为尚不支持 此处。
但是，以 iOS 4.2 的 iOS 部署目标发布应用程序可能会在很大程度上减少非视网膜显示屏用户的数量。
而用户不切换到新设备的主要原因在之前的答案中已经得到了完美的解释。 :)
Maybe its not possible right now as it isnt yet supported here.
But releasing your app with a iOS deployment target of iOS 4.2 may reduce the number of non-retina display users to a great extent.
And the main reason for users not switching to new devices is explained perfectly in the previous answer. :)
