LibGDX - iOS上的广告

Question

我正在使用LibGDX和RoboVM制作应用程序,而且我遇到了谷歌移动广告框架的问题.我到处搜索,但没有解决我的错误.

如果我在robovm.xml中声明这个框架就像这样

  <frameworkPaths>
    <path>libs</path>
  </frameworkPaths>
  <frameworks>
    <framework>UIKit</framework>
    <framework>OpenGLES</framework>
    <framework>QuartzCore</framework>
    <framework>CoreGraphics</framework>
    <framework>OpenAL</framework>
    <framework>AudioToolbox</framework>
    <framework>AVFoundation</framework>
    <framework>GoogleMobileAds</framework>
  </frameworks>

当我要创建IPA时,它会给我这个错误.

我怎么解决这个？
