angular-imgcache.js图像路径问题仅限iOS

几天来，我一直在努力解决这个问题。angular-imgcache.js模块在Android中工作，但在iOS中不工作。我可以检查Android上的文件系统和iOS上的应用程序容器。不同之处在于，在Android上，imgcache目录位于文件系统的根目录中，而iOS上，imgcache位于

Library/files/imgcache

下。下面是我刷新时在safari remote inspector中看到的消息

[Log] INFO: LocalFileSystem opened (vendors.min.js, line 852)
[Log] INFO: Local cache folder opened: /imgcache/ (vendors.min.js, line 852)

初始加载后，我可以通过修改此对象来覆盖filecache操作中使用的imagecache目录

ImgCache.attributes.dirEntry
Object
filesystem: Object
fullPath: "/imgcache/"
isDirectory: true
isFile: false
name: "imgcache"
nativeURL: "file:///var/mobile/Containers/Data/Application/CONTAINER_HASH/Library/files/imgcache/"
__proto__: Object


> ImgCache.attributes.dirEntry.fullPath = ImgCache.attributes.dirEntry.nativeURL
< "file:///var/mobile/Containers/Data/Application/CONTAINER_HASH/Library/files/imgcache/"
> ImgCache.cacheFile("https://URLPATH");
< undefined

初始化发生在

$ionicPlatform.ready

  // PhoneGap application
  if (navigator && navigator.splashscreen) {
    $ionicPlatform.ready(function() {
      console.log('$ionicPlatform');
      Analytics.init();

      if (phoneCheck.android) {
        ionic.Platform.isFullScreen = true;
      }
      if (phoneCheck.ios) {
        setTimeout(function() {
          navigator.splashscreen.hide();
          ImgCache.$init();
        }, 2500);
      }
    });
  }

  // PhoneGap application
  if (navigator && navigator.splashscreen) {
    $ionicPlatform.ready(function() {
      console.log('$ionicPlatform');
      Analytics.init();

      if (phoneCheck.android) {
        ionic.Platform.isFullScreen = true;
      }
      if (phoneCheck.ios) {
        setTimeout(function() {
          navigator.splashscreen.hide();
          ImgCache.$init();
        }, 2500);
      }
    });
  }
