1、Xcode工程使用CocoaPods管理第三方库时出现错误：
问题描述：
解决方法：
出现上述错误的原因一般是第三方库更新导致的，这时需要使用终端把该工程所引用到的所有第三方库进行更新
步骤：
1、打开终端，cd到当前工程的根目录，例：cd /Users/HO/Downloads/LZAlbum-master
2、然后输入pod install 回车，终端会自动检测改工程所应用到的库并且更新
注意：如果出现Updating local specs repositories，并且等了很久没有回应，代表命令pod install被墙了
改用：pod install --verbose --no-repo-update
3、这时终端执行更新库操作
4、最后打开工程，就可以正常运行了。
下面是我测试工程时敲入的命名和更新的响应，一并贴上：

5、当然，我在网上看到有有些人在一些情况下通过上面4个步骤之后，还会出现以下错误（本人没有遇到过）
/Users/wmm-mac/Documents/Program-SVN/Versions/code/iPhone/GeneralProject/Pods/Pods-resources.sh: line 5: /Users/wmm-mac/Documents/Program-SVN/Versions/code/iPhone/GeneralProject/Pods/resources-to-copy-GeneralProject.txt: Permission denied
那是因为Pod没有权限：
这时我们执行下面代码即可：
sudo chmod 777 Pods
