问题描述

当我将3gs（iOS 5.0.1）设备连接到Instruments时，我收到此错误消息

When i am connecting my 3gs(iOS 5.0.1) device to Instruments i am getting this error message

" Failed to start Instruments daemon for 'iOS' on  iPhone 3GS (v5.0.1)' (The service is invalid.)

当我重新连接设备时，此消息会出现在乐器上。如何使用此设备进行性能测试。

推荐答案

尝试连接iPod 4G时，我收到此错误消息。事实证明，我使用的是早期版本的XCode（4.2）中过时版本的Instruments。 （当我在Spotlight中搜索Instruments时，只出现此版本，因为更高版本的XCode将其工具隐藏在XCode.app包中。）您的情况可能不同但我怀疑您没有从XCode中的Profile命令运行Instruments IDE。

I received this error message while trying to run Instruments with an iPod 4G connected. It turned out that I was using an out-of-date version of Instruments from an earlier version of XCode (4.2). (When I searched for Instruments in Spotlight, only this version appeared because later versions of XCode hide their tools inside the XCode.app package.) Your circumstances may be different but I suspect that you did not run Instruments from the Profile command in the XCode IDE.

要验证这是否是问题，请检查仪器的版本（在关于仪器中）并验证它与XCode IDE的版本相同。 （对我来说，这些分别是4.2和4.5。）如果它们不匹配，请右键单击Applications文件夹中的XCode应用程序，然后选择显示包内容。在内容/应用程序中，您应找到正确版本的仪器。

To verify if this is the problem, check the version of Instruments (in 'About Instruments') and verify that it is the same version as your XCode IDE. (For me, these were 4.2 and 4.5 respectively.) If they do not match, right-click on the XCode app in your Applications folder and select 'Show Package Contents'. In Contents/Applications, you should find the correct version of Instruments.
