构建本地Pod库流程网上一搜一大堆就不再重复了。
主要的坑在是配置podspec文件。

Pod::Spec.new do |s|
  s.name         = "ProtocolBuffNetWorking"
  s.version      = "0.0.1"
  s.summary      = "Tool for networking, base on ProtocolBuff."
  s.description  = <<-DESC
  Tool for networking, base on ProtocolBuff.
                   DESC
  s.homepage     = "http://ProtocolBuffNetWorking"
  s.license      = "MIT"
  s.author             = { "yyf" => "765936789@qq.com" }
  s.platform     = :ios, "9.0"
  s.source       = { :git => "http://ProtocolBuffNetWorking.git", :tag => "#{s.version}" }
  s.source_files  = "ProtocolBuffNetWorking/ProtocolBufferModels/*.{h,m}", "ProtocolBuffNetWorking/NetWorkManager/*.{h,m,mm}","ProtocolBuffNetWorking/ProtocolBuffRequest/*.{h,m}","ProtocolBuffNetWorking/StaticLib/*.h"
  s.dependency 'Protobuf','~> 3.5.0'
  s.requires_arc = true
  s.vendored_libraries = 'ProtocolBuffNetWorking/StaticLib/*.a'
  s.libraries = 'c++.1'

  non_arc_files = "ProtocolBuffNetWorking/ProtocolBufferModels/*.{h,m}"
  s.exclude_files = non_arc_files

  s.subspec 'no-arc' do |sp|
    sp.requires_arc = false
    sp.source_files = non_arc_files
    end
end

自己用，描述啊，网址那些可以随便写。

出现的问题及解决

1、

'UIKit/UIKit.h' file not found

漏掉了下面这句

s.platform     = :ios, "9.0"

未指定iOS系统，所以找不到UIKit。
2、依赖第三方库Protobuf

s.dependency 'Protobuf','~> 3.5.0'

3、部分代码需要支持MRC

non_arc_files = "ProtocolBuffNetWorking/ProtocolBufferModels/*.{h,m}"
  s.exclude_files = non_arc_files

  s.subspec 'no-arc' do |sp|
    sp.requires_arc = false
    sp.source_files = non_arc_files
    end

4、引用自己的framework或.a文件

s.vendored_libraries = 'ProtocolBuffNetWorking/StaticLib/*.a'
s.vendored_frameworks = 'xxx/**/*.framework'

5、x86_64的错误，使用了未定义的c++函数。这是因为.a库是c++写的，需要添加系统的依赖库libc++.1.tdb。

s.libraries = 'c++.1'

6、图片资源

s.resource_bundles = {
    'LazyTableViewModel' => ['Assets/*.png']
  }

如果直接使用

[UIImage imageNamed:@“图片名"]

图片无法显示，这种方式默认是从mainBundle中去加载图片，会找不到图片。
可以通过路径来加载

    NSBundle *bundle = [NSBundle bundleForClass:[LazyTableViewModel class]];
    NSString *path = [bundle pathForResource:@"网络错误.png" ofType:nil inDirectory:@"LazyTableViewModel.bundle"];
    UIImage *image = [UIImage imageWithContentsOfFile:path];

本地库的使用

Podfile

target 'ProtocolBuffNetWorking' do
pod 'ProtocolBuffNetWorking', :path => '/路径/'
end

cd 到工程目录下

pod install
