谈一下为什么需要发布私有pod，公司使用cocoapod依赖的github上面的BlocksKit。我们从BlocksKit's issue也能发现一直存在crash，而最新提交还是two years ago 。看来我们只能自己去修改了。所以打算在clone一个，改完时候重新发个版本到公司内的gitlab上，这样自己就方便维护和使用了。
不过在解决这两个问题没少花时间，所以希望能帮助有类似问题的同学，为他们提供一种解决方法。
主要有两个问题：

• 在clone完项目之后，自己先试试了

pod lib lint --verbose

发现这个工程有问题，lint不过，提示的错误是：

……
 - ERROR | [BlocksKit/All] xcodebuild:  /Users/****/Desktop/BlocksKit/BlocksKit/DynamicDelegate/Foundation/NSURLConnection+BlocksKit.m:351:14: error: 'initWithRequest:delegate:startImmediately:' is unavailable: not available on watchOS
……

说是不支持watchOS，我点进去看了看initWithRequest：delegate：startImmediately方法，发现确实标有__WATCHOS_PROHIBITED

- (nullable instancetype)initWithRequest:(NSURLRequest *)request delegate:(nullable id)delegate startImmediately:(BOOL)startImmediately NS_DEPRECATED(10_5, 10_11, 2_0, 9_0, "Use NSURLSession (see NSURLSession.h)") __WATCHOS_PROHIBITED;

本身我的工程就不是在watchOS上运行的，那就不让它支持watchOS好了。可是在哪设置能不让他支持watchOS呢？
我先是试了试删掉一些target，发现不能解决问题，最后在.podspec文件下找到了可以设置是否支持watchOS的原因，下面是.podspec的部分代码

Pod::Spec.new do |s|
s.name                  = 'BlocksKit'
s.version               = '2.2.6'
s.license               = 'MIT'
……
s.osx.deployment_target = '10.8'
s.ios.deployment_target = '6.0'
s.watchos.deployment_target = '2.0'  
……
end

就把s.watchos.deployment_target = '2.0'这一行给删掉了，重新执行 pod lib lint发现这个问题解决，欣喜中……

• 迎来了第二个问题，

- ERROR | [BlocksKit/DynamicDelegate] xcodebuild: Returned an unsuccessful exit code. You can use `--verbose` for more information.
- NOTE  | [BlocksKit/DynamicDelegate] xcodebuild:  /Users/****/Desktop/BlocksKit/BlocksKit/DynamicDelegate/Foundation/NSCache+BlocksKit.h:6:9: fatal error: 'BKDefines.h' file not found
- NOTE  | [BlocksKit/DynamicDelegate] xcodebuild:  /Users/****/Desktop/BlocksKit/BlocksKit/DynamicDelegate/A2DynamicDelegate.h:6:9: fatal error: 'BKDefines.h' file not found
- NOTE  | [BlocksKit/DynamicDelegate] xcodebuild:  /Users/****/Desktop/BlocksKit/BlocksKit/DynamicDelegate/A2BlockInvocation.h:6:9: fatal error: 'BKDefines.h' file not found

从上面的信息我们能看到BlocksKit/DynamicDelegate这个子pod有问题。还是占一个完整的.podspec文件吧：

  Pod::Spec.new do |s|
    s.name                  = 'BlocksKit'
    s.version               = '2.2.6'
    s.license               = 'MIT'
    s.summary               = 'The Objective-C block utilities you always         wish you had.'
    s.homepage              = 'https://zwaldowski.github.io/BlocksKit'
    s.author                = { 'Zachary Waldowski' =>   '[email protected]',
                          'Alexsander Akers'  => '[email protected]' }
    s.source                = { :git => ' https://github.com/zwaldowski/BlocksKit.git', :tag => "v#{s.version}" }
    s.requires_arc          = true
    s.osx.deployment_target = '10.8'
    s.ios.deployment_target = '6.0'

    s.default_subspec = 'All'
    s.subspec 'All' do |ss|
    ss.dependency 'BlocksKit/Core'
    ss.dependency 'BlocksKit/DynamicDelegate'
    ss.ios.dependency 'BlocksKit/MessageUI'
    ss.ios.dependency 'BlocksKit/QuickLook'
    ss.ios.dependency 'BlocksKit/UIKit'
   end

   s.subspec 'Core' do |ss|
    ss.source_files = 'BlocksKit/BlocksKit.h', "BlocksKit/BKDefines.h", 'BlocksKit/Core/*.{h,m}'
  end

  s.subspec 'DynamicDelegate' do |ss|
      ss.source_files = 'BlocksKit/DynamicDelegate/*.{h,m}', 'BlocksKit/DynamicDelegate/Foundation/*.{h,m}'
 end

  s.subspec 'MessageUI' do |ss|
    ss.dependency 'BlocksKit/Core'
    ss.dependency 'BlocksKit/DynamicDelegate'
    ss.platform = :ios
   ss.source_files = 'BlocksKit/BlocksKit+MessageUI.h', 'BlocksKit/MessageUI/*.{h,m}'
    ss.ios.frameworks = 'MessageUI'
  end

  s.subspec 'QuickLook' do |ss|
    ss.dependency 'BlocksKit/Core'
    ss.dependency 'BlocksKit/DynamicDelegate'
    ss.platform = :ios
    ss.source_files = 'BlocksKit/BlocksKit+QuickLook.h', 'BlocksKit/QuickLook/*.{h,m}'
    ss.ios.frameworks = 'QuickLook'
  end

   s.subspec 'UIKit' do |ss|
    ss.dependency 'BlocksKit/Core'
    ss.dependency 'BlocksKit/DynamicDelegate'
    ss.platform = :ios
    ss.source_files = 'BlocksKit/BlocksKit+UIKit.h', 'BlocksKit/UIKit/*.{h,m}'
  end
end

这次我们能看到是BlocksKit/DynamicDelegate这个subspec的问题了吧。发现这个subspec的source_files是'BlocksKit/DynamicDelegate/*.{h,m}', 'BlocksKit/DynamicDelegate/Foundation/*.{h,m}'这些。我们从工程结构里看，下面是工程结构的截图：

可以看到出错的就是这几个文件，找不到.h文件，我试了试在buildSettings里面添加headerpath，发现没有用。翻遍了cocoapods的issues和Stack Overflow中cocoapod专栏，发现没找着原因。
最后突然发现，哎，这个 BKDefines.h不是在 core这个subspec中吗，有没有可能是因为 'DynamicDelegate'这个subspec没有依赖 core这个pod呢！想到这，就赶紧翻看了上面 .podspec文件，发现真的是没引用。于是我就在 DynamicDelegate 下加了对 core的依赖。如下：

s.subspec 'DynamicDelegate' do |ss|
  ss.source_files = 'BlocksKit/DynamicDelegate/*.{h,m}', 'BlocksKit/DynamicDelegate/Foundation/*.{h,m}'
  ss.dependency 'BlocksKit/Core' //新加了这行
 end

重新执行pod lib lint通过，就能够lint通过了。大功告成
