使用Cordova 3.7(文件://)从iOS 8的www文件夹加载资产

I have an hybrid app that works perfectly on iOS 7 using Cordova 3.7 and jQuery Mobile 1.3.2

我有一个混合应用程序，在iOS 7中使用Cordova 3.7和jQuery Mobile 1.3.2完美地运行。

I am testing it on iOS 8 and it is broken. I am requesting each page(view) of my app using absolute paths, using the file:// protocol, like:

我在ios8上测试它，它坏了。我请求使用绝对路径的应用程序的每一个页面(视图)，使用文件://协议，比如:

file:///var/mobile/Applications/<UUID>/MyApp.app/www/views/add-project.html

文件:/ / / var /移动/应用程序/ < UUID > / / add-project.html MyApp.app / www /视图

but i get the error:

但是我得到了错误:

Failed to load resource: The requested URL was not found on this server.

未能加载资源:在此服务器上未找到请求的URL。

I read about this bug, is that the problem?

我读到过这个错误，是这个问题吗?

Also, on iOS 8, the location of the www folder is a bit different from iOS 7, it resolves to:

此外，在ios8上，www文件夹的位置与ios7略有不同，它决定:

file:///var/mobile/Containers/Data/Application/<UUID>/MYApp.app/www/views/add-project.html

文件:/ / / var /移动/集装箱/数据/应用程序/ < UUID > / / add-project.html MYApp.app / www /视图

Is this correct?

这是正确的吗?

I tried the toURL() and toInternalURL() methods to have the absolute paths like:

我尝试了toURL()和toInternalURL()方法来获得绝对路径:

cdvfile://localhost/root/var/mobile/Containers/Bundle/Application/<UUID>/MyApp.app/ but I get always the same error. Any suggestion?

cdvfile:/ / localhost /根/ var /移动/集装箱/包/应用/ < UUID > / MyApp。应用程序/但我总是犯同样的错误。任何建议吗?

Thanks

To whoever might find this useful, I finally manage to solve the problem.

不管谁觉得这有用，我终于设法解决了这个问题。

The full path to the www folder on ios 8+ is:

ios8 +上www文件夹的完整路径是:

file:///private/var/mobile/Containers/Bundle/Application/<UUID>/<your_app>.app/www/

文件:/ / /私人/ var /移动/集装箱/包/应用程序/ < UUID > / < your_app > .app / www /

but when you request the application directory with Cordova, doing:

但是当你请求Cordova的应用程序目录时，

window.resolveLocalFileSystemURL(cordova.file.applicationDirectory, onSuccess, onError);

window.resolveLocalFileSystemURL(cordova.file。applicationDirectory、调用onSuccess onError);

it will give you a wrong path (Cordova 3.7 on iOS 8.1.2) like:

它会给你一个错误的路径(Cordova 3.7在iOS 8.1.2):

file:////var/mobile/Containers/Bundle/Application/<UUID>/<your_app>.app/

文件:/ / / / var /移动/集装箱/包/应用程序/ < UUID > / < your_app > .app /

using the toURL() method suggested on the docs

使用在文档中建议的toURL()方法。

Therefore you need to manually do a bit of tweaking

因此，您需要手动进行一些调整。

var path = fileSystem.toURL();//given by the success callback 

IOS_ASSETS_ABS_PATH = path.replace("file:////", "file:///private/");

IOS_ASSETS_ABS_PATH += "www/";

and bingo!

宾果!

I ran into the same problem and I managed to solve it. In my case, my problem was that every time I update the app, the new app has a different id than the last one. For instance, the path for the older app was:

我遇到了同样的问题，我设法解决了它。在我的例子中，我的问题是每次我更新应用程序时，新应用程序的id都与上一个不同。例如，旧的应用程序的路径是:

file:///var/mobile/Containers/Data/Application/7A3590E8-C78A-4F45-B5B9-51FD0BAFE524/Library/files/file.pdf

And new one:

和新一:

file:///var/mobile/Containers/Data/Application/1BC5FS-7B3B-90E8-C7C8-1B7C1984C2A71/Library/files/file.pdf

So even though my pdf files were still on the application data storage, I was using the wrong path since the app created a new application id. I solved this by creating a new function that updates my path every time there is an update. I find the application id by using:

因此，即使我的pdf文件仍然在应用程序数据存储中，我还是使用了错误的路径，因为应用程序创建了一个新的应用程序id。我通过以下方式找到了应用id:

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);

function onFileSystemSuccess(fileSystem) {
    // Do what you need here
}

The filesystem is an object contains the nativeURL inside the root.

文件系统是一个对象，包含根内的nativeURL。

Hope it helps!
