我在使用 codenameone 生成的 IOS 应用程序时遇到问题。该应用程序有两个多按钮。单击按钮时应用程序崩溃。应用程序并不总是在第一次点击时崩溃，但如果按下几次最终会崩溃。

最佳答案
我已经通过强制 CodenameOne 构建服务器使用旧 VM 解决了这个问题，直到解决了新 VM 的问题。
要强制构建服务器使用旧 VM，必须指定以下构建提示
ios.newVM = false
关于ios - Codenameone 生成的 IOS 8 App 崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28529575/
