Resize a textView based on it's content iOS || textView fit its content objective C || textView resize based on content swift

Solution:

In iOS textVIew will be scroll when text overflows its frame.in android it had an option that wrap content.So we can use the below technique to achieve that.

Objective c:

    - (void)textViewDidChange:(UITextView *)textView

    {

    CGFloat tViewWidth = textView.frame.size.width;

    CGSize newSize = [textView sizeThatFits:CGSizeMake(tViewWidth, MAXFLOAT)];

    CGRect newFrame = textView.frame;

    newFrame.size = CGSizeMake(fmaxf(newSize.width, tViewWidth), newSize.height);

    textView.frame = newFrame;

    }

Swift:

    func textViewDidChange(_ textView: UITextView) {

                    let tViewWidth = textView.frame.size.width

                    let newSize = textView.sizeThatFits(CGSize(width: tViewWidth, height: CGFloat.greatestFiniteMagnitude))

                    textView.frame.size = CGSize(width: max(newSize.width, tViewWidth), height: newSize.height)

    }
