使用CocoaPods更新第三方库出错的解决办法

使用CocoaPods更新第三方库出错的解决办法

执行完pod install或pod update之后，控制台抛出以下警告信息：

• [!] The xx [Debug] target overrides the PODS_ROOT build setting defined in `Pods/Target Support Files/Pods-/Pods-.debug.xcconfig'. This can lead to problems with the CocoaPods installation

  • Use the $(inherited) flag, or
  • Remove the build settings from the target.

• [!] The xx [Debug] target overrides the LIBRARY_SEARCH_PATHS build setting defined in `Pods/Target Support Files/Pods-xx/Pods-xx.debug.xcconfig'. This can lead to problems with the CocoaPods installation

  • Use the $(inherited) flag, or
  • Remove the build settings from the target.

• [!] The xx [Debug] target overrides the HEADER_SEARCH_PATHS build setting defined in `Pods/Target Support Files/Pods-xx/Pods-xx.debug.xcconfig'. This can lead to problems with the CocoaPods installation

  • Use the $(inherited) flag, or
  • Remove the build settings from the target.

• [!] The xx [Release] target overrides the PODS_ROOT build setting defined in `Pods/Target Support Files/Pods-xx/Pods-xx.release.xcconfig'. This can lead to problems with the CocoaPods installation

  • Use the $(inherited) flag, or
  • Remove the build settings from the target.

• [!] The xx [Release] target overrides the LIBRARY_SEARCH_PATHS build setting defined in `Pods/Target Support Files/Pods-xx/Pods-xx.release.xcconfig'. This can lead to problems with the CocoaPods installation

如果不解决此问题的话，会出现由于部分库文件找不到而导致的种种问题：
（1）编译失败，抛出Undefined symbols for architecture i386错误
（2）调用库中的方法，抛出unrecognized selector sent to instance错误

解决方法如下：

• 1 打开工程所在文件夹，找到.xcodeproj文件，右键选择【显示包内容】，找到project.pbxproj文件
• 2 打开project.pbxproj文件，查找
  PODS_ROOT
LIBRARY_SEARCH_PATHS
HEADER_SEARCH_PATHS
LIBRARY_SEARCH_PATHS

把和这些相关的内容都删除

• 3 重新执行pod install，此时应该就没有上面出现的警告信息了
• 4 编译并运行
