iOS 科爾多瓦應用程序在閃屏后掛起

[英]iOS cordova app hangs after splash screen

 原文  2020-02-24 21:54:34  3   1    ios/ xcode/ cordova/ ionic-framework

問題描述

我正在編譯我的應用程序的新版本，在設備和模擬器上的啟動畫面之后，屏幕只是空白。 我構建的應用程序的最后一個版本運行良好……當前版本在 Android 設備上運行良好。 下面的日志與應用程序啟動時沒有問題時幾乎相同，所以我不知道是什么導致了這個 WOD。 我該如何解決這個問題？ 我還能如何獲得有關屏幕掛起原因的真實日志？

在 Safari Inspector 中，我可以看到整個應用程序的 html 加載看起來很好......似乎一切都在那里。 同樣，控制台日志中報告的 JS/AngularJS 錯誤為零。

我添加了一些 console.logs 以查看我是否可以查明事情至少到達的位置，但甚至無法在 Xcode 或 Safari 檢查器中打印到控制台。

這是我的環境：

離子信息

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

和控制台日志，我不相信以下任何錯誤/警告應該導致應用程序掛起或白屏 - 我之前已經看過所有這些，但沒有一個影響應用程序。 大多數我已經研究過並且看起來是良性的。

我曾經在 Cordova 的應用程序中遇到過類似的問題（使用 ExtJS 框架編寫，而不是 Ionic），應用程序會在啟動畫面后掛起，主要是在 iOS 上。

問題

Cordova 加載良好，但框架卻沒有。 （出於未知原因）因此，加載了index.html並觸發了deviceready事件，但框架為空且無法啟動。

解決方法

我從來沒有找到問題的根源（我懷疑它與你的無關），但是由於deviceready被觸發，我在運行時檢查框架是否已加載，如果沒有，則重新加載整個應用程序。 對於用戶點視圖，啟動畫面只出現一次，然后消失，屏幕保持白色（當應用程序在后台重新加載時），然后應用程序出現。

在我的index.html ，類似的東西

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);
    }
}
