iOS 3.x上的自动引用计数 [英] Automatic Reference Counting on iOS 3.x

问题描述

使用arc 3.1编译的应用程序可以在iOS 3.1.x设备上使用吗?理想情况下，我想使我们的应用程序仅适用于iOS 4.x及更高版本，但我们仍有一些用户仍在运行iOS3.x.我无法再访问装有iOS 3的设备.

Does an app compiled with arc turned on work with iOS 3.1.x devices? Ideally I would like to make our app work only with iOS 4.x and higher but we have some users still running iOS 3.x. I no longer have access to devices with iOS 3.

有人测试过吗?

推荐答案

在您至少找到了达到这种效果的官方文档并且也许自己也进行了测试之前，我不会指望ARC可以回溯到iOS3.x. .这是至少有一种观点支持使用ARC编写的应用程序甚至不能在所有版本的iOS 4上运行的观点.

I wouldn't count on ARC working back to iOS 3.x until you've at least found official documentation to that effect and perhaps tested it yourself as well. Here's at least one opinion that supports the notion that apps written using ARC may not even work on all versions of iOS 4.
