为 CocoaPods 的 pod 设置部署目标

Question

我使用 CocoaPods 来管理我项目中的依赖项。我写了 Podfile：

target 'MyApp' do
  platform :ios, '8.0'
  # Uncomment this line if you're using Swift or would like to use dynamic frameworks
  #use_frameworks!

  # Pods for MyApp
  pod 'KeepLayout', :git => 'https://github.com/iMartinKiss/KeepLayout', :tag => 'v1.6.0'
  pod 'EasyMapping'

  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'MyAppUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

此文件适用于 CocoaPods 0.x，但在我更新到 CocoaPods 1.0 后无法编译项目。跑完后

pod update 

我无法编译我的项目，出现错误：

/Users/<...>/Pods/KeepLayout/Sources/KeepAttribute.m:195:1: 无法合成弱属性，因为当前部署目标不支持弱引用

我看到每个库都是用不同的部署目标构建的。例如 KeepLayout 是用 4.3 部署目标构建的。

我如何确定每个 pod 依赖项的构建目标？

Answer 1

虽然 CocoaPods 的某些开发版本（以及 1.0 之前的版本）可能已将项目的部署目标传播到 pod，但 1.0 中不再是这种情况。要解决此问题，当前开发人员建议使用安装后挂钩。

这是一种蛮力方法，可以为生成的 Pod 项目中的每个 Pod 强制执行硬编码部署目标。将此粘贴到您的Podfile的end

：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.2'
    end
  end
end

Answer 2

由于

Podfile

使用像

platform :ios, '9.0'

这样的指令为Pods/Pods.xcodeproj项目指定“iOS部署目标”（又名

IPHONEOS_DEPLOYMENT_TARGET

），你只需要remove每个Deployment Target信息建立目标。
通过将此添加到您的

Podfile

来做到这一点

platform :ios, '9.0' # set IPHONEOS_DEPLOYMENT_TARGET for the pods project
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

灵感来自 github 帖子 和 Alex Nauda 的回答。

Answer 3

这里是为 Pod 目标永久设置部署目标的方法。

Goto -> podfile -> 添加以下代码

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = "12.0"
     end
  end
end

Answer 4

虽然 Alex Nauda 接受的答案很好，但让 Pod 从应用程序继承目标可能是更好的解决方案。 🚀

app_ios_deployment_target = Gem::Version.new('9.2') # Change to your current deployment target

platform :ios, app_ios_deployment_target.version

# Let Pods targets inherit deployment target from the app
# This solution is suggested here: https://github.com/CocoaPods/CocoaPods/issues/4859
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |configuration|
      pod_ios_deployment_target = Gem::Version.new(configuration.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])
      if pod_ios_deployment_target <= app_ios_deployment_target
        configuration.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
  end
end

斯威夫特 5 简单的解决方案复制粘贴下面的代码到结束你的 podFile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.1' //set your minimum version your all pods will set to mininum 13.1 version :-)
    end
  end
end

pod install

快乐编码

Answer 6

将目标更改为“11.0”

platform :ios, '11.0'

Answer 7

1) 搜索 IPHONEOS_DEPLOYMENT_TARGET

2) 更改 iOS 部署目标
