裝載相機連接到電腦中的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 

這是爲什麼？如何解決這個問題？

Answer 1

此錯誤說明您缺少/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)/Symbols/System/Library/Frameworks/IOKit.framework框架。您是否安裝了xcode/developer工具的其他副本？如果是這樣，您可能需要複製此版本的設備支持。

選項1

這個框架通常是/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"），這樣你就可以將它複製到您的Xcode正在尋找通過開放Terminal.app和輸入：

[ 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" 

如果失敗，是因爲沒有/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)目錄，那麼你可以做什麼是這樣的：

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

然後：2再次

下載Xcode中/開發工具

[ 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" 

---

選項，將其安裝到的東西，除了/Developer，如/Developer-4.2，然後複製目錄/Developer-4.2/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)至/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.5 (8L1)

---

選項3

照照/Developer/Platforms/iPhoneOS.platform/DeviceSupport/目錄，可能還有其他的版本，但沒有4.3.5 (8L1)。如果有4.3.5但沒有4.3.5 (8L1)那麼你可以做的是使兩者之間的符號鏈接在期限以下命令：

[ 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，只是通過運行/Developer/Library/uninstall-devtools命令卸載Xcode中，然後下載並重新安裝。
