使用 CMake 将 Swift 导入 Objective-C

Question

我有一个带有 CMake 的 QT 应用程序。 CMake 生成

.xcodeproj

和 CocoaPods 从以下 .xcworkspace

 生成 

Podfile

：

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, :deployment_target => '14.0'

target 'MyApp' do
  pod 'YandexMobileAdsAdMobAdapters'
  pod 'YandexMobileAdsIronSourceAdapters'
  pod 'YandexMobileAdsMediation'
  pod 'YandexMobileAdsInstream'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '14.0'
    end
  end
end

pod install

命令生成以下标头：

./Pods/YandexMobileAdsIronSourceAdapters/YandexMobileAdsIronSourceAdapters.xcframework/ios-arm64_x86_64-simulator/YandexMobileAdsIronSourceAdapters.framework/Headers/YandexMobileAdsIronSourceAdapters-umbrella.h
./Pods/YandexMobileAdsIronSourceAdapters/YandexMobileAdsIronSourceAdapters.xcframework/ios-arm64_x86_64-simulator/YandexMobileAdsIronSourceAdapters.framework/Headers/YandexMobileAdsIronSourceAdapters-Swift.h

./Pods/YandexMobileAdsInstream/YandexMobileAdsInstream.xcframework/ios-arm64/YandexMobileAdsInstream.framework/Headers/YandexMobileAdsInstream-Swift.h
./Pods/YandexMobileAdsAdMobAdapters/YandexMobileAdsAdMobAdapters.xcframework/ios-arm64_x86_64-simulator/YandexMobileAdsAdMobAdapters.framework/Headers/YandexMobileAdsAdMobAdapters-Swift.h
./Pods/YandexMobileAdsAdMobAdapters/YandexMobileAdsAdMobAdapters.xcframework/ios-arm64_x86_64-simulator/YandexMobileAdsAdMobAdapters.framework/Headers/YandexMobileAdsAdMobAdapters-umbrella.h
./Pods/YandexMobileAdsAdMobAdapters/YandexMobileAdsAdMobAdapters.xcframework/ios-arm64/YandexMobileAdsAdMobAdapters.framework/Headers/YandexMobileAdsAdMobAdapters-Swift.h
./Pods/YandexMobileAdsAdMobAdapters/YandexMobileAdsAdMobAdapters.xcframework/ios-arm64/YandexMobileAdsAdMobAdapters.framework/Headers/YandexMobileAdsAdMobAdapters-umbrella.h

但我无法将它们包含到我的项目中的

.mm

文件中。我尝试了各种路径，例如

#import <YandexMobileAds.h>
#import <YandexMobileAds/YandexMobileAds-Swift.h>
#import <YandexMobileAds/YandexMobileAds.h>

但没有成功：

1. 为什么没有被发现？

我的第一个想法是以某种方式公开它们，但我没有在

Header

页面上找到

Build Phases

部分：

（像

Generate .rcc/qmlcache .. 

这样的任务有很多，但不是

Headers

）。

XCode 显示了以下 Pod：

2. 另一个问题是为什么不生成

   YandexMobileAdsMediation

   header？ （但仅限 YandexMobileAds）

请参阅 Yandex 文档，了解如何在 Swift 项目中使用其包。

3. 是否可以使用 CMake 将 Swift 包添加到项目中？ （可以链接到 Swift 库，但是 Swift 包呢？）

编辑1：

我不太了解 Objective-C 语法，但至少我能够在生成的

InterstitialAdLoader

标头中找到所需的类名

YandexMobileAds-Swift.h

，并且我可以假设它是在这里定义的：

grep -ri "InterstitialAdLoader" . --include=\*.h

./YandexMobileAds-Swift.h:@protocol YMAInterstitialAdLoaderDelegate;
./YandexMobileAds-Swift.h:SWIFT_CLASS_NAMED("InterstitialAdLoader")
./YandexMobileAds-Swift.h:@interface YMAInterstitialAdLoader : NSObject
./YandexMobileAds-Swift.h:@property (nonatomic, weak) id <YMAInterstitialAdLoaderDelegate> _Nullable delegate;
./YandexMobileAds-Swift.h:SWIFT_PROTOCOL_NAMED("InterstitialAdLoaderDelegate")
./YandexMobileAds-Swift.h:@protocol YMAInterstitialAdLoaderDelegate <NSObject>
./YandexMobileAds-Swift.h:/// \param adLoader A reference to an object of the <code>InterstitialAdLoader</code> class that invoked the method.
./YandexMobileAds-Swift.h:- (void)interstitialAdLoader:(YMAInterstitialAdLoader * _Nonnull)adLoader didLoad:(YMAInterstitialAd * _Nonnull)interstitialAd;
./YandexMobileAds-Swift.h:/// \param adLoader A reference to an object of the <code>InterstitialAdLoader</code> class that invoked the method.
./YandexMobileAds-Swift.h:- (void)interstitialAdLoader:(YMAInterstitialAdLoader * _Nonnull)adLoader didFailToLoadWithError:(YMAAdRequestError * _Nonnull)error;

因此理论上将

YandexMobileAds-Swift.h

包含到我的

.mm

文件中可以朝着正确的方向迈进。

Answer 1

我用这个更改了 Podfile：

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, :deployment_target => '14.0'

target 'LinesGameQt' do
  pod 'YandexMobileAdsMediation', '7.5.1'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '14.0'
    end
  end
end

并且能够使用

 编译我的 

.mm

文件

#import <YandexMobileAds/YandexMobileAds-Swift.h>
