我正在尝试构建一个 iOS 框架，为此，我使用了一些依赖项，并且单独构建框架项目时没有出现错误，当我在演示应用程序中使用 CocoaPods 安装时，出现以下错误Undefined symbol: _OBJC_CLASS_$_DFPRequest.
这就是我在框架中的内容：
Podfile
platform :ios, '10.0'
use_frameworks!
target 'mylib' do
pod 'PrebidMobile'
pod 'Google-Mobile-Ads-SDK'
pod 'mopub-ios-sdk'
pod 'GoogleAds-IMA-iOS-SDK'
end
MyLib.podspec
Pod::Spec.new do |s|
...
s.platform = :ios, "10.0"
s.swift_version = '5.0'
s.xcconfig = {
:LIBRARY_SEARCH_PATHS => '$(inherited)',
:OTHER_CFLAGS => '$(inherited)',
:OTHER_LDFLAGS => '$(inherited)',
:HEADER_SEARCH_PATHS => '$(inherited)',
:FRAMEWORK_SEARCH_PATHS => '$(inherited)'
}
s.framework = [
'CoreTelephony',
'SystemConfiguration',
'UIKit',
'Foundation'
]
s.subspec 'core' do |core|
core.source_files = 'Source/**/*.{h,m,swift}'
end
s.dependency 'PrebidMobile'
s.dependency 'Google-Mobile-Ads-SDK'
s.dependency 'mopub-ios-sdk'
s.dependency 'GoogleAds-IMA-iOS-SDK'
end
横幅.swift
import UIKit
import PrebidMobile
import GoogleMobileAds
import MoPub
enum BannerFormat: Int {
case html
case vast
}
class BannerController: UIViewController, GADBannerViewDelegate, MPAdViewDelegate {
@IBOutlet var appBannerView: UIView!
@IBOutlet var adServerLabel: UILabel!
var bannerFormat: BannerFormat = .html
var adServerName: String = ""
private var adUnit: AdUnit!
private let amRequest = DFPRequest()
private var amBanner: DFPBannerView!
private var mpBanner: MPAdView!
override func viewDidLoad() {
super.viewDidLoad()
adServerLabel.text = adServerName
}
override func viewDidDisappear(_ animated: Bool) {
adUnit?.stopAutoRefresh()
}
func viewControllerForPresentingModalView() -> UIViewController! {
return self
}
}
现在在应用程序演示中，我有
Podfile
platform :ios, '10.0'
use_frameworks!
target 'appdemo (iOS)' do
pod 'MyLib', :git => 'https://...mylib.git'
end
所以，只需运行pod install && pod update并构建应用程序演示我已经收到错误。
既然单独运行框架是有效的，那么我在这里做错了什么，安装框架不起作用？
