Xcode 4.2无法调试iOS 4.2.1（8C148） [英] Xcode 4.2 can't debug iOS 4.2.1 (8C148)

问题描述

我最近更新到Xcode 4.2。我还将我的新iPad 2和iPod（最新一代）更新为iOS 5.我构建我的应用程序，可以调试它们没有问题。

我的旧iPod运行iOS 4.2。 1（8C148）不运行，不会发生任何错误。
顶部中心面板说完成在iPod One上运行MyApp。 （iPod One是我的第一个iPod touch的名称）

Xcode的底部有一个闪烁，好像它几乎进入调试器，并且正在显示底部输出面板，但它没有。主要的休息点也不会阻止它。

我没有错误，没有任何事情可以继续。

我已经更新了所有配置配置文件，恢复了设备，选择了用于开发，没有任何帮助。

由于Xcode没有反馈，我不知道该怎么做。

ps该应用程序运行在所有的模拟器也很好。

当我最初选择iPod我看到以下系列在管理器的控制台中的信息显示在管理器中：

解决方案

我有同样的问题，但我解决了。原因
无反向架构（默认情况下Xcode4.2使用标准的arch = armv7） - >添加armv6

I recently updated to Xcode 4.2. I also updated my new iPad 2 and iPod (latest generation) to iOS 5. I build my app and can debug them no problem.

My older iPod running iOS 4.2.1 (8C148) doesn't run and doesn't give any errors. The top center panel says "Finished running MyApp on iPod One". (iPod One is the name of my first iPod touch)

There is a flicker at the bottom of Xcode as if it almost went into the debugger and was about to show the bottom output panel but it doesn't. A break point in main doesn't stop it either.

I have no errors and nothing to go on.

I have renewed all provisioning profiles, restored the device, selected "use for development", nothing has helped.

Since there is no feed back from Xcode I do not know what to do.

p.s. The app runs in all of the simulators fine as well.

When I initially select the iPod I see the following series of messages in the console for the devices as shown from the Organizer:

Thu Oct 20 09:42:49 unknown lockdownd[16] : 2ffea000 handle_connection: Could not receive USB message #6 from Xcode.

解决方案

I had the same problem, but I solved it. The cause unsuported architecture (by default Xcode4.2 uses standard arch= armv7 ) -> add armv6
