1，多行文本控件的创建

1 2 3 4

var textview= UITextView (frame: CGRectMake (10,100,200,100)) textview.layer.borderWidth=1  //边框粗细 textview.layer.borderColor= UIColor .grayColor(). CGColor //边框颜色 self .view.addSubview(textview)

2，是否可编辑

1	textview.editable= false

3，内容是否可选

1	textview.selectable= false

4，属性font设置字体，textColor设置字体颜色，textAlignment设置对齐方式 

5，给文字中的电话号码和网址自动加链接

1 2 3 4

textview.dataDetectorTypes = UIDataDetectorTypes . None //都不加链接 textview.dataDetectorTypes = UIDataDetectorTypes . PhoneNumber //只有电话加链接 textview.dataDetectorTypes = UIDataDetectorTypes . Link //只有网址加链接 textview.dataDetectorTypes = UIDataDetectorTypes . All //电话和网址都加

6，自定义选择内容后的菜单

我们在看新闻或小说的时候，常常在点选文字后会弹出菜单进行选择，复制等操作。我们可以在这个菜单上添加一些其他内容，如加上“邮件”“微信”等按钮选项

import UIKit   class ViewController : UIViewController {        override func viewDidLoad() {          super .viewDidLoad()                    var mail = UIMenuItem (title: "邮件" , action: "onMail" )          var weixin = UIMenuItem (title: "微信" , action: "onWeiXin" )          var menu = UIMenuController ()          menu.menuItems = NSArray (array: [mail,weixin])             }            func onMail(){          println ( "mail" )      }            func onWeiXin(){          println ( "weixin" )      }        override func didReceiveMemoryWarning() {          super .didReceiveMemoryWarning()      } }
