I haven’t implemented it yet. Also, I couldn’t find any plugin which can do so.
There are few open issues regarding that.
Try checking there for a solution or if you find any, it will be great if you can suggest them to add it to the plugin.
Bro, I couldn’t manage to achieve this feature for iOS till I was working on that paroject. Please try cordova-plugin-privacyscreen, it has a recent commit for latest iOS support. You may also check cordova-plugin-prevent-screenshot if the prior one doesn’t work. Let us know if any of above plugins work for you in iOS.
In order to use screenshieldkit in Ionic, you require a JavaScript middleware/interface of this plugin. Please check with plugin’s owners if they provide anything for it.
