想要实现:

ios – Adding space/padding to a UILabel (Swift) – Stack Overflow

How do you add inset to UILabel (iOS Swift)? – Stack Overflow

ios – Inset text in UILabel from left – Stack Overflow

最后换成TextView,然后加上textContainerInset即可:

                self.systemNoticeTextView = UITextView()
               
                self.systemNoticeTextView.text = notifMsg.notice
                self.systemNoticeTextView.textAlignment = NSTextAlignment.Left
                self.systemNoticeTextView.textColor = ColorSystemNoticeText
                self.systemNoticeTextView.font = FontSystemNotice
                self.systemNoticeTextView.backgroundColor = ColorSystemNoticeBackground
                self.systemNoticeTextView.layer.borderWidth = 1
                self.systemNoticeTextView.layer.borderColor = ColorSystemNoticeBackground.CGColor
                self.systemNoticeTextView.layer.cornerRadius = 2
               
                self.systemNoticeTextView.editable = false
                self.systemNoticeTextView.selectable = false
                self.systemNoticeTextView.scrollEnabled = false
               
                self.systemNoticeTextView.textContainerInset = InsetSystemNotice
               
                self.contentView.addSubview(self.systemNoticeTextView)
               
                constrain(systemNoticeTextView) {systemNoticeLabel in
                    systemNoticeLabel.top == systemNoticeLabel.superview!.top + PaddingYMessageTVC
                    systemNoticeLabel.centerX == systemNoticeLabel.superview!.centerX
                    systemNoticeLabel.bottom == systemNoticeLabel.superview!.bottom
                    systemNoticeLabel.width <= systemNoticeLabel.superview!.width (2 * (WidthAvatarPadding + SizeAvatarImage + BubbleArrowWidth))
