iOS:在使用Cocoapods安装shareSDK时出现的link路径错误

CocoaPods 错误 target overrides the `OTHER_LDFLAGS`...

Xcode 升级到 6.0 后，更新 CocoaPods，出现了如下的警告

[!] The `Paopao [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 `Paopao [Debug]` target overrides the `OTHER_LDFLAGS` 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 `Paopao [Release]` target overrides the `PODS_ROOT` build setting defined in `Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The `Paopao [Release]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] Your Podfile has had smart quotes sanitised. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice.

[!] The `KenJiao [Debug]` target overrides the `FRAMEWORK_SEARCH_PATHS` 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 `KenJiao [Release]` target overrides the `FRAMEWORK_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

后果： 这种警告是不能忽视的，它带来的直接后果就是无法通过编译。

错误截图：

原因：产生此警告的原因是项目 Target 中的一些设置，CocoaPods 也做了默认的设置，如果两个设置结果不一致，就会造成问题。

解决办法：

1.分别在项目中定义`PODS_ROOT` 和 `Other Linker Flags`的地方，把他们的值用`$(inherited)`替换掉，进入终端，执行pod update ,上面的警告就解决一部分了；

2.在项目中定义的'Framework search paths'的地方，也是把他们的值用`$(inherited)`替换掉,最后编译，通过，ok！

$(inherited)作用：自动执行父类的相关代码,执行完后再回来执行系类的代码,也就是继承关系

网上还流行另外一种简单粗暴的方法

点击项目文件 project.xcodeproj，右键`显示包内容`，用文本编辑器打开`project.pbxproj`，删除`OTHER_LDFLAGS`的地方，保存，回到 Xcode，编译通过。
