我开发了 ionic 应用程序，它在 android 和浏览器上运行得很好，现在我在 ios 上运行。当我在模拟器上运行应用程序时，应用程序启动并不断显示第一个( ionic 符号页面)，并保持原样。
我检查了日志，
我发现错误 Internal navigation rejected: <allow-navigation not set>如本 question 中所回答我关注了<allow-navigation href="*" />
但在下一次运行中我得到了新的错误，
navigation rejected - <allow-navigation> not set for url='gap://ready'
谁能告诉我它到底是什么gap://ready
我的 logcat 作为，

最佳答案
'gap' 在 iOS 上使用 UIWebView 时是必需的，也是 js/ native 通信所必需的。 此标记必须添加到 index.html 上，覆盖元标记 content-security-policy。
您可以在https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-whitelist/#content-security-policy 上双击此信息。和 https://content-security-policy.com/和 https://developer.apple.com/documentation/uikit/uiwebview/1617943-gapbetweenpages , https://developer.apple.com/documentation/uikit/uiwebview
关于ios - 导航被拒绝 - <allow-navigation> 没有为 url ='gap://ready' 设置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48809260/
