My repository for RichEditorView most likely does the same thing. We use a JavaScript command called execCommand
in which the browser decides what is undone. The command, itself, is most likely: document.execCommand('undo', false, null);
I'm not too sure since I don't use this repo, but it most likely does this. There really isn't much leeway unless you use a DispatchQueue like so (this is pseudocode since I don't use this repository):
override func viewDidLoad() {
super.viewDidLoad()
getLastContent()
}
var undo_html = ""
private func getLastContent() {
DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: {
undo_html = self.editorView.get_html() // Assuming the editor controller is editorView
self.getLastContent() // Recursive
}
}
Then you can rewrite the undo functionality by using that variable undo_html
instead by setting the html to that for undo. Best have a redo variable in that case, as well, since you're technically changing the text, not undoing.
