iOS Cordova应用程序更新后看不到用cordova.plugin.file保存的图像 [英] iOS cordova app not seeing images saved with cordova.plugin.file after app update

问题描述

iOS Cordova应用程序更新后看不到本地保存的图像.在此之前，一切正常.如何使用cordova.plugin.file动态设置相对URL?

iOS Cordova application does not see locally saved images after app update. Before that everything works fine. How do i set dynamically relative url with cordova.plugin.file?

我在config.xml中使用过:

I used in config.xml:

<preference name="iosExtraFilesystems" value="library,library-nosync,documents,documents-nosync,cache,bundle,root" />
<preference name="iosPersistentFileLocation" value="Library" />

cordova.plugin.file将数据保存到:

The cordova.plugin.file saves data to:

cordova.file.dataDirectory;

但是在应用程序更新后，它们从文件夹中消失了，我在控制台中看到了它们.我阅读了有关更新后ios复制文件的信息，我必须设置从照相机本地保存的图像的相对路径.但是我不知道如何让ios看到图像.

But after app update they disappear from the folder i see them in in console. I read about ios copying files after update and that i have to set relative path to the images that i save locally from camera. But i do not know how to do it for ios to see the images.

推荐答案

好吧，事实是我将它们保存到了temp目录，ios在应用程序更新时将其清除.开始将图像保存到Documents/目录后，一切开始正常运行.

Well, the thing was that I saved them to a temp directory, which is cleared by ios on app update. After I started saving the images to the Documents/ directory, everything started working fine.
