RXswift Setting maximum number of characters of UITextView

 Problem:

I want to set maximum number of characters for UITextview.How do i achieve that using rxswift?

Solution:

//    MARK: - Limit textview charecters

func limitTextViewCharacters(tv:UITextView?, limit: Int) {

    if let tView = tv {

        guard tView.text.count > limit else {

            return

        }

        

        let index = tView.text.index(tView.text.startIndex, offsetBy: limit)

        tView.text = String(tView.text.prefix(upTo: index))

    }

}

Add the above function in utils.

Then in your viewcontroller add the below code in viewdidload

        TxtView.rx.text.changed

            .subscribe(onNext: {_ in

                limitTextViewCharacters(tv: self.TxtView, limit: TextLimit)

                let name = self.TxtView.text

            }).disposed(by: self.disposeBag)
