UITextView.AttributedText 属性

  • 参考

定义

命名空间:
UIKit
程序集:
Xamarin.iOS.dll

作为特性化字符串的文本视图的内容。

[ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 6, 0, ObjCRuntime.PlatformArchitecture.All, null)]
public virtual Foundation.NSAttributedString AttributedText { [ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 6, 0, ObjCRuntime.PlatformArchitecture.All, null)] [Foundation.Export("attributedText", ObjCRuntime.ArgumentSemantic.Copy)] get; [ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS, 6, 0, ObjCRuntime.PlatformArchitecture.All, null)] [Foundation.Export("setAttributedText:", ObjCRuntime.ArgumentSemantic.Copy)] set; }
member this.AttributedText : Foundation.NSAttributedString with get, set

属性值

注解

如果应用程序开发人员希望在 中使用多个文本样式， UITextView则必须使用此属性。 以下示例使用 M：Foundation.NSMutableAttributableString.AddAttribute* 修改不同范围的颜色和字体，如图所示。

//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;
