Cocoapod 0.38.0和AFNetworking 2.5 AF_APP_EXTENSIONS编译错误

本文介绍了Cocoapod 0.38.0和AFNetworking 2.5 AF_APP_EXTENSIONS编译错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的项目有9个目标：

- Prod
- Prod_app_extension_1
- Prod_app_extension_2
- Beta
- Beta_app_extension_1
- Beta_app_extension_2
- Dev
- Dev_app_extension_2
- Dev_app_extension_2

我正在使用0.38.2 cocoapod版本和2.5.4 AFNetworking。

I'm using 0.38.2 cocoapod version and 2.5.4 AFNetworking.

我正在尝试将AFNetworking与cocoapod，但编译时出现 AF_APP_EXTENSIONS 错误。在网上搜索解决方案后，我了解了问题所在，并发现定义预处理程序宏 AF_APP_EXTENSIONS 可以解决此问题。

I'm trying to use AFNetworking with cocoapod but I get the AF_APP_EXTENSIONS error while compiling. After searching for the solution on the web, I understand the problem and found that defining the 'preprocessor macros' AF_APP_EXTENSIONS can fix the problem.

但这是一个难题：默认情况下， AF_APP_EXTENSIONS 已正确添加到我的6个app_extensions中。另一方面，当我浏览Pods目标时，每个Pod都分开了：

But here is the struggle : By default, AF_APP_EXTENSIONS is correctly added into my 6 app_extensions. In the other hand, when I navigate through my Pods target, each Pods are separated :

- NSDate+TimeAgo
- AFNetworking
- iRate
- AppUtils
- Prod
- Prod_app_extension_1
- Prod_app_extension_2
- Beta
- Beta_app_extension_1
- Beta_app_extension_2
- Dev
- Dev_app_extension_2
- Dev_app_extension_2

在我做的另一个项目中，所有豆荚都是这样生成的：

In another project I made, all pods are generated this way :

- Prod
- Pods-Prod-NSDate+TimeAgo
- Pods-Prod-AFNetworking
- Pods-Prod-iRate
- Pods-Prod-AppUtils

- Prod_app_extension_1
- Pods-Prod_app_extension_1-NSDate+TimeAgo
- Pods-Prod_app_extension_1-AFNetworking
- Pods-Prod_app_extension_1-iRate

- Prod_app_extension_2
- Pods-Prod_app_extension_2-NSDate+TimeAgo
- Pods-Prod_app_extension_2-AFNetworking
- Pods-Prod_app_extension_2-iRate

- Beta
- Pods-Beta-NSDate+TimeAgo
- Pods-Beta-AFNetworking
- Pods-Beta-iRate
- Pods-Beta-AppUtils

- Beta_app_extension_1
- Pods-Beta_app_extension_1-NSDate+TimeAgo
- Pods-Beta_app_extension_1-AFNetworking
- Pods-Beta_app_extension_1-iRate

- Beta_app_extension_2
- Pods-Beta_app_extension_2-NSDate+TimeAgo
- Pods-Beta_app_extension_2-AFNetworking
- Pods-Beta_app_extension_2-iRate

- Dev
- Pods-Dev-NSDate+TimeAgo
- Pods-Dev-AFNetworking
- Pods-Dev-iRate
- Pods-Dev-AppUtils

- Dev_app_extension_1
- Pods-Dev_app_extension_1-NSDate+TimeAgo
- Pods-Dev_app_extension_1-AFNetworking
- Pods-Dev_app_extension_1-iRate

- Dev_app_extension_2
- Pods-Dev_app_extension_2-NSDate+TimeAgo
- Pods-Dev_app_extension_2-AFNetworking
- Pods-Dev_app_extension_2-iRate

我认为这就是为什么我的预处理器宏 AF_APP_EXTENSIONS 不是定义到 AFNetworking广告连播目标中。

I think this is why my 'preprocessor macros' AF_APP_EXTENSIONS isn't define into the 'AFNetworking' Pods target.

这是我的Podfile：

Here is my Podfile :

platform :ios, '7.0'

xcodeproj 'myProj.xcodeproj'


def generic_pods
    pod 'NSDate+TimeAgo'
    pod 'AFNetworking', '~> 2.0'
end

def app_pods
    pod 'iRate'
    pod 'AppUtils',
end



target "Prod" do
    generic_pods
    app_pods
end

target "Prod_app_extension_1" do
    generic_pods
end

target "Prod_app_extension_2" do
    generic_pods
end

target "Beta" do
    generic_pods
    app_pods
end

target "Beta_app_extension_1" do
    generic_pods
end

target "Beta_app_extension_2" do
    generic_pods
end

target "Dev" do
    generic_pods
    app_pods
end

target "Dev_app_extension_1" do
    generic_pods
end

target "Dev_app_extension_2" do
    generic_pods
end

不知道是什么问题，这让我发疯。

I don't know what the problem is, and it's driving me crazy.

推荐答案

因为cocoapod版本为0.38.0，所以pod目标已被重复删除。这意味着，不是为每个项目目标（ Pods-MyApp-AFNetworking， Pods-MyExtension-AFNetworking ...）构建一个AFNetworking，而是仅生成一个AFNetworking Pod目标（ Pods-AFNetworking）。

Since 0.38.0 cocoapod version, pod target are De-duplicate. It means, instead of bulding an AFNetworking for each of your project target ('Pods-MyApp-AFNetworking', 'Pods-MyExtension-AFNetworking', ...) only one AFNetworking pod target is generated ('Pods-AFNetworking').

AFNetworking要求将'AF_APP_EXTENSIONS'标志添加到GCC_PREPROCESSOR_DEFINITIONS 中，以便在添加到应用扩展名时进行编译。

AFNetworking require 'AF_APP_EXTENSIONS' flag into the GCC_PREPROCESSOR_DEFINITIONS to compile when added to app-extensions.

直到0.37.2 cocoapod版本，可以通过添加安装后例程从项目Podfile中添加标志：

Until the 0.37.2 cocoapod version, it was possible to add the flag from your project Podfile by adding a post-install routine :

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        if ar.include? target.name
            target.build_configurations.each do |config|
                config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', 'AF_APP_EXTENSIONS=1']
            end
        end
    end
end

不幸的是，使用去重复cocoapod功能，不再可以向应用程序添加AF_APP_EXTENSIONS标志扩展Pod分别针对目标。

Unfortunatly, with the De-duplicate cocoapod feature, it's no longer possible to add the AF_APP_EXTENSIONS flag to the app extention pod targets separately.

我发现唯一的编译方法是创建一个文件：〜/ .. cocoapods / config.yaml （使用cocoapod时默认情况下不存在，您可以在终端上使用以下内容创建它：

The only way I found is to compile is to create a file : ~/.cocoapods/config.yaml (not present by default when you use cocoapod, you can create it with the terminal) with this content :

deduplicate_targets: false

这样，不会对Pod进行重复数据删除，您可以在安装后将AF_APP_EXTENSIONS添加到您的应用中扩展名GCC_PREPROCESSOR_DEFINITIONS。

This way, pods aren't not de-duplicated and you can post-install add the AF_APP_EXTENSIONS into your app extensions GCC_PREPROCESSOR_DEFINITIONS.

我只是希望他们能找到防止此问题的好方法。

I just hope they will found a good way to prevent this problem.
