有没有办法从iOS 5.1降级到iOS 5.0？ [英] Is there a way to downgrade from iOS 5.1 to iOS 5.0?

问题描述

我不小心在5.1上升级了我的iPhone 4，现在我无法在雪豹上测试Xcode 4.2。我不想升级到狮子下载xcode 4.3因为我很多人说它放慢了他们的mac并且还有其他几个问题。有没有办法从iOS 5.1降级到iOS 5.0，并能够在我的雪豹上再次测试xcode 4.2上的应用程序？如果有人帮助感谢，我将不胜感激。

I accidentally upgraded my iPhone 4 on 5.1 and now I can't test on Xcode 4.2 on my snow leopard. I don't want to upgrade to lion to download xcode 4.3 because I heart many people that said it slowed down their macs and had other several problems. Is there a way to downgrade from iOS 5.1 to iOS 5.0 and be able to test again my applications on xcode 4.2 on my snow leopard? I'd be grateful if someone helps thanks.

推荐答案

Xcode 4.2可以与iOS 5.1设备配合使用。

Xcode 4.2 can be made to work with iOS 5.1 devices.

从这里下载Xcode 4.3。将4.3 SDK和Device Support文件夹从4.3安装程序复制到Xcode 4.2文件夹中。

Download Xcode 4.3 from here. Copy the 5.1 SDK and Device Support folders from the 4.3 installer into your Xcode 4.2 folder.

前者进入平台/ iPhoneOS.platform / Developer / SDKs ，后者进入平台/ iPhoneOS.platform / DeviceSupport
