CocoaPods在使用中的几个问题

来源： http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/
1.

当把CocoaPods生成的workspace移动到上层目录时，需要改下Pods.xcconfig和工程里的一些设置，就通常没什么难度。

当遇到这个问题时：

Could not automatically select an Xcode project. Specify one in your Podfile like so:

xcodeproj 'path/to/Project.xcodeproj'

在Podfile文件里指定下工程目录就行了，比如我在Podfile文件添加这行就行了：

......

xcodeproj 'MessageNews/MessageNews.xcodeproj'

......

主要是让Pod找到子目录中的工程文件。

2.

当在update或install时遇到这个问题：

Unable to find a specification for `xxxxx (~> 1.x.x)` depended upon by Podfile.

只需要把当前Pod的目录清理一下就行了。在终端执行以下命令：

pod repo remove master

pod setup

setup成功后执行install或update即可。

3.

出现以下错误时："

[!] Oh no, an error occurred.

It appears to have originated from your Podfile at line 1.

解决方案： You need reinstall cocoapods: so

sudo gem uninstall cocoapods
sudo gem install cocoapods
pod setup

“[!] The platform of the target `Pods` (iOS 6.0) is not compatible with XXX which has a minimum requirement of iOS 6.0 - OS X 10.7.”

可以修改Podfile为：
platform :ios, '6.0'
