            UILabel addressLabel = new UILabel();
            float labelWidth = (float)addressLabel.Frame.Width;
            SizeF size = ((NSString)addressLabel.Text).StringSize(addressLabel.Font, constrainedToSize: new SizeF(labelWidth, 100),
                    lineBreakMode: UILineBreakMode.WordWrap);
            var labelFrame = addressLabel.Frame;
            labelFrame.Size = new SizeF(labelWidth, size.Height);
            addressLabel.Frame = labelFrame;
