Ionic 应用程序在卸载后不会删除本地数据

Question

I have found a solution for Android but not able to get one for iOS.

• I logged into my app
• Perform some tasks that save data in local storage
• Go to Home and uninstall the app
• Install App again
• All previously stored data reappear

It should remove all data upon uninstallation.

If you are using Cordova, add the following in your config.xml -

For iOS

Inside <platform name="ios"> -

<preference name="BackupWebStorage" value="none" />

Default value is cloud . https://cordova.apache.org/docs/en/latest/config_ref/index.html

For Android

Inside <platform name="android"> -

<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">
    <application android:allowBackup="false" android:fullBackupContent="false" />
</edit-config>
