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，并且您已尝试过以下操作，该怎么办：

选择ios app后，在Safari中打开控制台日志---＆gt;没有显示任何内容，因为在应用程序启动之前您无法连接，这意味着您无法看到任何启动日志...（据我所知）
仔细查看了ios模拟器的系统日志，但未发现任何揭示线索。有很多错误，但不确定哪个属于哪个，如果有的话？我会在这里复制并粘贴日志......
已下载Ripple并尝试在其上运行应用。纹波仿真器上的一切都很好。该应用程序似乎适用于浏览器和涟漪，但ios模拟器上的白色屏幕。

Answer 1

当我更新ios平台时，我点击了WSoD，我认为（不确定）它还更新了一些插件。我完全无法调试问题，因为我没有任何控制台错误，而一切正常，没有实时重新加载。

事实证明问题出在白名单上。该应用程序根本不允许访问livereload服务器。我在config.xml添加了以下行，并且重新开始重新加载：

<allow-navigation href="*"/>

当然这是非常宽松的，不建议用于实际生产，但至少它可以解决问题。从技术上讲，如果不使用实时重载，这是不必要的，因此可以简单地省略生产。但是，如果担心安全问题，可以选择：

<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

Answer 2

在我的启动画面之后和我的cordova 3.6应用的第一页之前，我看到了一个白色屏幕。当我在平台iOS文件夹中安装org.apache.cordova.splashscreen插件并在autohidesplashscreen = false中创建config.xml时，问题就消失了。

然后，您可以使用以下方法隐藏设备中的启动画面：

document.addEventListener("deviceready", onDeviceReady, false);
        function onDeviceReady(){          
            console.log("ON DEVICE READY!!!");
            navigator.splashscreen.hide();
        }

要添加的另一件事是我仅使用.xcodeproj运行项目而不使用终端，我使用index.html内的platform/iOS。

在ios白色屏幕上的Cordova混合app
