ios - iOS Cordova 应用程序在启动画面后挂起

问题描述

我正在编译我的应用程序的新版本，并且在设备和模拟器上出现启动屏幕后，屏幕只是一片空白。我构建的应用程序的最后一个版本运行良好......当前版本在 Android 设备上运行良好。以下日志与应用程序启动时没有问题时几乎相同，所以我不知道是什么导致了这个 WOD。我该如何解决这个问题？我还能如何获得有关屏幕为何挂起的真实日志？

在 Safari Inspector 中，我可以看到整个应用程序的 html 加载效果很好……看起来一切都在那里。同样，控制台日志中报告的 JS/AngularJS 错误为零。

我添加了一些console.logs，看看我是否可以查明事情至少到达了哪里，但即使它们在Xcode或Safari检查器中打印到控制台也无法确定。

这是我的环境：

离子信息

Ionic:

   Ionic CLI         : 5.4.4 (/usr/local/lib/node_modules/ionic)
   Ionic Framework   : ionic1 1.0.0
   @ionic/v1-toolkit : 1.0.22

Cordova:

   Cordova CLI       : 9.0.0 (cordova-lib@9.0.1)
   Cordova Platforms : ios 5.0.1
   Cordova Plugins   : cordova-plugin-ionic-keyboard 2.1.3, (and 32 other plugins)

Utility:

   cordova-res : 0.6.0 (update available: 0.9.0)
   native-run  : 0.2.8 (update available: 0.3.0)

System:

   ios-deploy : 1.9.4
   ios-sim    : 8.0.2
   NodeJS     : v10.16.3 (/usr/local/bin/node)
   npm        : 6.11.2
   OS         : macOS High Sierra
   Xcode      : Xcode 10.1 Build version 10B61

并且控制台日志，我认为以下任何错误/警告都不应该导致应用程序挂起或进入白屏 - 我以前见过所有这些，但它们都没有影响应用程序。我研究过的大多数似乎都是良性的。

解决方案

我曾经在 Cordova 的应用程序中遇到过类似的问题（使用 ExtJS 框架编写，而不是 Ionic），该应用程序会在启动屏幕之后挂起，主要是在 iOS 上。

问题

Cordova 加载良好，但框架却没有。（出于未知原因）因此，index.html已加载并deviceready触发了事件，但框架为空且无法启动。

解决方法

我从来没有找到问题的根源（我怀疑它与你的问题无关），但由于deviceready被解雇，我在运行时检查框架是否已加载，如果没有则重新加载整个应用程序。对于用户点一个视图，闪屏只出现一次，然后淡出，屏幕保持白色（当应用程序在后台重新加载时）并且应用程序出现。

在我的index.html，类似的东西

function onDeviceReady() {
    //...

    try {
        var isFrameworkLoaded = ....

        if (isFrameworkLoaded !== true) {
            console.log("onDeviceReady() : FORCE RELOAD");
            location.reload();  // Reloads the index.html page, and doesn't reload the splashscreen
            return;
        }
    } catch (e) {
        console.warn("onDeviceReady : Error : " + e);
    }
}
