ios - flutter 中的 flutter inappwebview 警告

Question

我在我的 flutter 应用程序中实现了一个 youtube 播放器，当我运行它时，构建将失败并引发 deprication 错误。

我目前使用的是 2012 年年中的 macbook，所以我无法使用最新版本的 x 代码。我当前的版本是 Version 12.4 。所以为了在 ios 上使用 flutter，我使用的是 flutter 2.5。

所以现在当我尝试使用 youtube 播放器时，它不会构建应用程序。

我使用的包是 youtube_player_flutter: ^8.0.0。该消息在应用程序 WebView 中指示。

if #available(iOS 10.0, *) {
                configuration.ignoresViewportScaleLimits = options.ignoresViewportScaleLimits
                
                var dataDetectorTypes = WKDataDetectorTypes.init(rawValue: 0)
                for type in options.dataDetectorTypes {
                    let dataDetectorType = Util.getDataDetectorType(type: type)
                    dataDetectorTypes = WKDataDetectorTypes(rawValue: dataDetectorTypes.rawValue | dataDetectorType.rawValue)
                }
                configuration.dataDetectorTypes = dataDetectorTypes
                
                configuration.mediaTypesRequiringUserActionForPlayback = options.mediaPlaybackRequiresUserGesture ? .all : []
            } else {
                // Fallback on earlier versions
                configuration.mediaPlaybackRequiresUserAction = options.mediaPlaybackRequiresUserGesture
            }

以及在应用程序 WebView 选项中

if #available(iOS 10.0, *) {
                realOptions["mediaPlaybackRequiresUserGesture"] = configuration.mediaTypesRequiringUserActionForPlayback == .all
                realOptions["ignoresViewportScaleLimits"] = configuration.ignoresViewportScaleLimits
                realOptions["dataDetectorTypes"] = Util.getDataDetectorTypeString(type: configuration.dataDetectorTypes)
            } else {
                realOptions["mediaPlaybackRequiresUserGesture"] = configuration.mediaPlaybackRequiresUserAction
            }

我取消了 platform: ios, '9.0' 的注释并在末尾替换为

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
    end
  end
end

替换这些解决了另一个错误(不包括在这个问题中)，但它似乎不适用于这些。我怎样才能解决这个问题？我之前没有使用过 xcode。

自过去 2 天以来，我一直面临这个问题。

您不需要下载 X-code-14 版本。

只需打开 X-code 并运行显示错误的项目，然后单击错误并点击修复。
