Xcode6: CocoaPods 错误 target overrides the `OTHER_LDFLAGS`...

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.

    - 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.

 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。

而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。

我想要使用 CocoaPods 中的设置，分别在我的项目中定义`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

 警告没了，回到 Xcode，build通过。

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。
