ld: library not found for -lXXX

解决方案：
将 PodS --> Build Settrings --> Build Active Architecture Only 设置为 NO
Build Active Architecture Only.png
The XXX [Debug] target
[!] The
XXX [Debug]target overrides theOTHER_LDFLAGSbuild setting defined inPods/Target Support Files/Pods-XXX/Pods-XXX.debug.xcconfig'. This can lead to problems with the CocoaPods installation \- Use the \$(inherited)` flag, or
- Remove the build settings from the target.
根据提示信息我们可以使用 `$(inherited)`标识，来消除这个警告：
在 Project --> Targets --> Build Settrings --> Other Linker Flags 中，添加 $(inherited)
