基本属性:

//textView尺寸和位置let textViewWidth: CGFloat = 223let textViewHeight: CGFloat = 198let textViewTopView: CGFloat = 240let textViewFrame = CGRect(x: 22, y: textViewTopView, width: textViewWidth, height: textViewHeight)let textView = UITextView(frame: textViewFrame)textView.text =  "    我们的生活几乎离不号码，如电话号码、手机号码、车牌号码、门牌号码等等。号码为什么会影响一个人的运势？其实号码也包含有一定的吉凶数理，这就像姓名会影响运势命运的意义是一样的。"

效果:

加上几个常用属性

 //textView是否可编辑,是否可选中textView.allowsEditingTextAttributes = falsetextView.isSelectable = true//字体颜色,背景颜色,字体大小,字体对齐方式textView.textColor = UIColor.greentextView.backgroundColor = UIColor.orangetextView.font = UIFont.systemFont(ofSize: 12.0)textView.textAlignment = .center

效果:

改为富文本

// 创建可变属性字符串let attribute = NSMutableAttributedString(string: textView.text)// 设置段落样式let paragraphStyle = NSMutableParagraphStyle()paragraphStyle.alignment = .centerparagraphStyle.lineSpacing = 10// 设置属性字典let dic = [NSAttributedString.Key.foregroundColor: UIColor.red,NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 22.0),NSAttributedString.Key.paragraphStyle: paragraphStyle]// 添加属性字典attribute.addAttributes(dic, range: NSMakeRange(16, textView.text.count - 16))// 设置textView的attributedTexttextView.attributedText = attribute

效果:

设置文字与边框间距,显示边框

//设置文本内容与边框的间距textView.textContainerInset = UIEdgeInsets(top: 20, left: 20, bottom: 20, right: 20)//显示边框textView.layer.borderColor = UIColor.cyan.cgColortextView.layer.borderWidth = 2.0
