Question

我用ionic 4和cordova构建了一个应用程序。在android上，该应用程序运行像一个咒语，但在iOS上，我遇到了一些奇怪的问题……就像其他问题一样（Ionic IOS app NSURLConnection error 1100，ionic 4 app shows white screen on ios with error code 1100）。该应用程序离子化版本运行良好，没有任何错误，并且仅对未使用的导入发出了一些警告。而且，xcode的构建是快速而成功的。但是，当应用程序在真实设备或模拟器上运行时，我只会出现空白的空白屏幕。在控制台中，我通过其他调试得到了这一点：

我发现提到了一些类似的问题，并且还添加了环境变量（CFNETWORK_DIAGNOSTICS = 1）用于高级网络日志记录，以在控制台（整个文件：https://pastebin.com/yecJ5Vzy）中获得更多信息（或在此处找到一些摘要）： / p>

稍后在控制台日志中：

2019-05-03 10:59:50.278000+0200 MyNiceApp[3426:1312114] NSURLConnection finished with error - code -1100
2019-05-03 10:59:50.278024+0200 MyNiceApp[3426:1312114] NSURLConnection finished with error - code -1100

该应用似乎无法加载自己的文件。.由于错误-1100表示NSURLErrorFileDoesNotExist

Answer 1

遇到了同样的问题，经过一番苦苦挣扎和研发，这才对我有用。

似乎相对路径是由IOS占用的，因此在您的src-> index.html中，请更改此设置基本href =“ /” 至基本href =“ ./”（/开头的点号）

这将加载所有相关的js文件（cordova.js，polyfill.js等）

1100错误是由于绝对路径而找不到文件。

Answer 2

在研究了很多东西之后，我的解决方案是执行以下命令：

ionic cordova plugin add cordova-plugin-ionic-webview --save

在iOS上运行离子应用时出现NSURLConnection错误1100
