对于为什么要另外创建一个podspec文件库，如何在项目中引入自己创建的私有库，不要忘了Profile文件中加入source这一项（这一项的内容就是你podspec仓库的地址）下面这篇文章有说明

podspec文件描述：
#
# Be sure to run `pod lib lint mypodlib.podspec' to ensure this is a
# valid spec before submitting.
#
# Any lines starting with a # are optional, but their use is encouraged
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#
Pod::Spec.new do |s|
s.name = 'mypodlib'
s.version = '1.0.0'
s.summary = 'this is my first lib'
# This description is used to generate tags and improve search results.
# * Think: What does it do? Why did you write it? What is the focus?
# * Try to keep it short, snappy and to the point.
# * Write the description between the DESC delimiters below.
# * Finally, don't worry about the indent, CocoaPods strips it!
s.description = <<-DESC
TODO: Add long description of the pod here.
DESC
s.homepage = 'https://coding.net'
# s.screenshots = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
s.license = { :type => 'MIT', :file => 'LICENSE' }
s.author = { 'lerpo' => 'face_book@foxmail.com' }
s.source = { :git => 'https://git.coding.net/waga/PodTestLibrary.git', :tag => s.version.to_s }
# s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'
s.ios.deployment_target = '8.0'
s.source_files = 'mypodlib/Classes/**/*'
# s.resource_bundles = {
# 'mypodlib' => ['mypodlib/Assets/*.png']

# s.public_header_files = 'Pod/Classes/**/*.h'
# s.frameworks = 'UIKit', 'MapKit'
# s.dependency 'AFNetworking', '~> 2.3'

Podfile 文件描述：
platform :ios, '9.0'
source 'https://git.coding.net/waga/mypod.git'
target 'myPodDemo' do
# Uncomment the next line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!
pod 'mypodlib','~>1.0.0'
# pod 'mypodlib', :git => 'https://git.coding.net/waga/PodTestLibrary.git',:tag => '1.0.0'
target 'myPodDemoTests' do
inherit! :search_paths
# Pods for testing
end
target 'myPodDemoUITests' do
inherit! :search_paths
# Pods for testing
