装载相机连接到电脑中的iOS

慢

我收到以下警告：

warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/IOKit.framework/IOKit (file not found). 
warning: No copy of IOKit.framework/IOKit found locally, reading from memory on remote device. This may slow down the debug session. 
warning: Tried to remove a non-existent library: /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/IOKit.framework/IOKit 

这是为什么？如何解决这个问题？

Answer 1

此错误说明您缺少/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/IOKit.framework框架。您是否安装了xcode/developer工具的其他副本？如果是这样，您可能需要复制此版本的设备支持。

选项1

这个框架通常是/System/Library/Frameworks/IOKit.framework可用（如果它不存在使用此命令找到它：find /System -type d -name "IOKit.framework"或find /Developer -type d -name "IOKit.framework"），这样你就可以将它复制到您的Xcode正在寻找通过开放Terminal.app和输入：

[ 16:01 root@MacBookPro/]# sudo cp -rv /System/Library/Frameworks/IOKit.framework "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/IOKit.framework" 

如果失败，是因为没有/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)目录，那么你可以做什么是这样的：

[ 16:01 root@MacBookPro/]# mkdir -p "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/" 

然后：2再次

下载Xcode中/开发工具

[ 16:01 root@MacBookPro/]# sudo cp -rv /System/Library/Frameworks/IOKit.framework "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/IOKit.framework"

选项，将其安装到的东西，除了/Developer，如/Developer-4.2，然后复制目录/Developer-4.2/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)至/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)

---

选项3

照照/Developer/Platforms/iPhoneOS.platform/DeviceSupport/目录，可能还有其他的版本，但没有4.3.5 (8L1)。如果有4.3.5但没有4.3.5 (8L1)那么你可以做的是使两者之间的符号链接在期限以下命令：

[ 16:01 root@MacBookPro/]# cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/ 
[ 16:01 root@MacBookPro/]# ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 "4.3.5 (8L1)"

或者，只是通过运行/Developer/Library/uninstall-devtools命令卸载Xcode中，然后下载并重新安装。
