iOS Cordova应用程序更新后看不到用cordova.plugin.file保存的图像

Question

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?

I used in config.xml:

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

The cordova.plugin.file saves data to:

cordova.file.dataDirectory;

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.

Answer 1

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.

See docs here https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/
