Application developers must use this property if they desire the use of multiple text styles in the UIKit.UITextView. The following example uses Foundation.NSMutableAttributableString.AddAttribute to modify the color and font in a various ranges, as shown in the image.
C# Example
//UITextView default
var atts = new UIStringAttributes();
atts.ForegroundColor = UIColor.Blue;
var txt = "Text Kit.\n Lorem ipsum different font dolor sit amet, consectetur adipiscing elit.";
var attributedString = new NSMutableAttributedString(txt,atts);
//Multiple type styles.
attributedString.BeginEditing();
attributedString.AddAttribute(UIStringAttributeKey.ForegroundColor, UIColor.Red, new NSRange(0, 10));
attributedString.AddAttribute(UIStringAttributeKey.Font, UIFont.PreferredFontForTextStyle(UIFontTextStyle.Headline), new NSRange(0, 10));
attributedString.AddAttribute(UIStringAttributeKey.Font, UIFont.FromName("Georgia", 20), new NSRange(23, 14));
attributedString.EndEditing();
TextView.AttributedText = attributedString;
