ios - ios白色屏幕上的Cordova混合应用程序

Question

如果使用cordova emulate ios在ios模拟器上启动应用程序时出现白屏，该怎么办，并且您已经尝试以下操作:

选择ios app --->后，在Safari中打开了控制台日志，这什么也没显示，因为在应用程序启动之前您无法连接，这意味着您看不到任何启动日志...(据我所知)

在系统日志中仔细查看了ios模拟器，但没有发现任何线索。有很多错误，但不确定是哪一个错误？我将日志复制并粘贴到此处...

下载了Ripple，并尝试在其上运行该应用程序。在纹波仿真器上一切都很好。该应用程序似乎可以在浏览器上正常运行，但在ios模拟器上却显示白屏。

Answer 1

我在更新ios平台时碰到了WSoD，我认为(不确定)它也更新了一些插件。我完全无法调试问题，因为在没有实时重新加载的情况下一切正常，我没有收到任何控制台错误。

事实证明，问题出在白名单上。根本不允许该应用访问livereload服务器。我在config.xml中添加了以下几行，实时重新加载开始重新工作:

<allow-navigation href="*"/>

当然，这是非常宽松的，不建议在实际生产中使用，但至少可以解决这个问题。从技术上讲，如果不使用实时重新加载，则没有必要，因此可以在生产中将其省略。但是，如果考虑到安全性，则可以选择以下替代方法:

<allow-navigation href="*://localhost/*"/>

但是在执行此操作时，有必要在运行 --address时添加 emulate选项:

$ ionic emulate -lcs --address localhost ios
