使用Swift构建Cocoapod并依赖Objective-C框架

Question

我知道关于这个主题已经有一些关于SO的问题,但是很少有人接受了答案,我认为我没有找到与我相同的问题.

我正在构建一个Swift pod,在我的代码中,我依赖于Google Maps iOS SDK,它被捆绑为一个.framework文件.该项目在Xcode中构建正常,但是我很难将lib发布到Cocoapods.

我设法有一个Podspec几乎使用该pod lib lint命令验证的文件.但是,现在我已将Google-Maps-iOS-SDKpod 添加为Podspec文件中的依赖项,但它失败并显示以下消息:

$ pod lib lint

[!]'Pods'目标具有包含静态二进制文件的传递依赖:(/private/var/folders/n2/qyjfpk6n7zz_mngtwswlmsy00000gn/T/CocoaPods/Lint/Pods/Google-Maps-iOS-SDK/GoogleMaps.framework)

$

这是预期的吗？为什么我不能在我自己的基于Swift的pod中添加Google Maps iOS SDK作为pod引用？

这是Podspec:

Pod::Spec.new do |s|
s.name                  = '(name)'
s.version               = '1.0.0'
s.summary               = '(summary)'
s.platforms             = { :ios => '8.0', :osx => '10.10' }
s.ios.deployment_target = '8.0'
s.osx.deployment_target = '10.10'
s.license               = { :type => 'BSD', :file => 'LICENSE' }
s.source_files          = 'Sources/*.{h,swift}', '*.framework'
s.source                = { :git => "https://github.com/(Github repo).git", :tag => "1.0.0" }
s.requires_arc          = true
s.frameworks             = "Foundation", "CoreLocation"
s.author                = { 'Romain L' => '(email)' }
s.dependency 'Google-Maps-iOS-SDK'
end

如果我不将Google Maps iOS SDK作为依赖项包含在内,则会pod lib lint在桥接标题中失败,并抱怨它无法找到<GoogleMaps/GoogleMaps.h>(找不到文件).

我被卡住了,我不知道这是Cocoapods 0.36(仍处于测试阶段)或者我做错了什么的错误.

谢谢你的帮助!

我终于在SO上发现了另一个处理类似问题的线程:通过CocoaPods添加了Google Maps for iOS的Swift项目中的链接器错误.

似乎错误是由于糟糕的Podspec文件(在Google Maps iOS SDK端)和Cocoapods 0.36 Beta中的错误的组合造成的.

实际上,可以使用@ fz.针对Google地图修改的Podspec文件解决问题:https://stackoverflow.com/a/28471830/145997 .另一篇文章也非常感兴趣,了解如何vendored_frameworks设置工程Podspec是:http://codereaper.com/blog/2014/creating-a-pod-with-crashreporter/.

因此,要在Pod项目中正确导入Google Maps iOS SDK,请首先使用以下内容Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
# altered version of Google's Podspec
pod 'Google-Maps-iOS-SDK', :podspec => "https://raw.githubusercontent.com/Reflejo/GoogleMapsPodspec/master/Google-Maps-iOS-SDK.podspec.json"
use_frameworks! # don't forget this!

我现在只需要通过我的Swift代码引用Google Maps类import GoogleMaps.而且,为了分发Pod,我的决赛Podspec现在类似于以下内容:

Pod::Spec.new do |s|
    s.name                  = 'MyPod'
    s.version               = '1.0.0'

    s.homepage              = "https://github.com/..."
    s.summary               = '(pod summary)'
    #s.screenshot            = ""

    s.author                = { 'Romain L' => '(email)' }
    s.license               = { :type => 'BSD', :file => 'LICENSE' }
    s.social_media_url      = "https://twitter.com/_RomainL"
    s.platforms             = { :ios => '8.0' }
    s.ios.deployment_target = '8.0'

    s.source_files          = 'MyCode/*.{h,swift}'
    s.module_name           = 'MyPod'
    s.source                = { :git => "https://github.com/....git", :tag => "1.0.0" }
    s.requires_arc          = true
    s.libraries             = "c++", "icucore", "z" # required for GoogleMaps.framework
    s.frameworks            = "AVFoundation", "CoreData", "CoreLocation", "CoreText", "Foundation", "GLKit", "ImageIO", "OpenGLES", "QuartzCore", "SystemConfiguration", "GoogleMaps" # required for GoogleMaps.framework
    s.vendored_frameworks   = "Dependencies/GoogleMaps.framework" # Put the Google-provided framework in that subfolder of your Pod project
    #s.dependency              'Google-Maps-iOS-SDK' # Careful! this will cause errors if enabled!
end

我现在能够在Xcode中启动一个新的iOS应用程序,并使用以下内容Podfile链接到我自己的pod,它本身引用了Google Maps iOS SDK:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
pod 'MyPod'
use_frameworks! # do not forget this!

不是那么容易,但毕竟是可行的!但希望Google能够尽快Podspec为Swift开发修补其文件.
