let textview = UITextView(frame:CGRect(x:10, y:100, width:200, height:100))

textview.layer.borderColor = UIColor.gray.cgColor //边框颜色
self.view.addSubview(textview)

textview.isEditable = false

3，内容是否可选
|

|
textview.isSelectable = false

5，给文字中的电话号码和网址自动加链接

textview.dataDetectorTypes = [] //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
