将iPhone应用程序降级到以前的SDK是否安全? [英] Is it safe to downgrade an iphone app to a previous SDK?

问题描述

我发布了带有2.2.1 SDK的应用程序，以意识到我毫无意义地失去了仍然使用固件2.2的大量客户(请参阅本文:

I have released an app with the 2.2.1 SDK, to realize that I'm pointlessly losing a big percentage of customers still on firmware 2.2 (See this article: http://arstechnica.com/apple/news/2009/03/app-store-lessons-firmware-followup.ars) So I'm thinking of updating the app to the previous SDK, 2.2.

我想知道这样做是否有人遇到任何问题?对于已经安装了先前版本的客户来说，安装我的降级"更新安全吗?

I was wondering if anyone has run into any problem doing this? Is this safe for customers who have already installed the previous version, to install my "downgrading" update?

推荐答案

我已将应用商店应用程序从2.2.1更改为2.2，并且切换时没有遇到任何问题.

I have changed an app store app from 2.2.1 to 2.2, and I did not encounter any problems when switching.
