目前我正在尝试将此插件 flutter-zsdk 用作我的项目的依赖项，但我无法为 iOS 构建/运行该项目。对于 Android，该项目可以正常构建/运行，但对于 iOS，我收到以下错误：

Running Xcode build

注意 1：此插件使用静态库 zsdk.a 与打印机进行通信。

注意 2：我在 Android Studio 中将 Flutter-zsdk 插件作为一个项目打开，我能够为 Android 和 iOS 构建/运行 example_app，无需任何额外操作……只需打开项目，然后构建并运行一切正常。

所以我的问题是： 构建一个使用插件的项目，而该插件又使用静态 library.a 有什么不同吗？为了能够正确构建/运行这种插件依赖项，我是否必须在我的 iOS 项目配置中进行设置？

终于找到了解决办法。我从 Podfile 中评论了 use_frameworks!，一切正常...
