What would you like to do?
A UILabel subclass that adds padding around the text and handles layout properly.
import UIKit
class NRLabel : UILabel {
var textInsets = UIEdgeInsets.zero {
didSet { invalidateIntrinsicContentSize() }
}
override func textRect(forBounds bounds: CGRect, limitedToNumberOfLines numberOfLines: Int) -> CGRect {
let insetRect = UIEdgeInsetsInsetRect(bounds, textInsets)
let textRect = super.textRect(forBounds: insetRect, limitedToNumberOfLines: numberOfLines)
let invertedInsets = UIEdgeInsets(top: -textInsets.top,
left: -textInsets.left,
bottom: -textInsets.bottom,
right: -textInsets.right)
return UIEdgeInsetsInsetRect(textRect, invertedInsets)
}
override func drawText(in rect: CGRect) {
super.drawText(in: UIEdgeInsetsInsetRect(rect, textInsets))
}
}
@IBDesignable
extension NRLabel {
@IBInspectable
var leftTextInset: CGFloat {
set { textInsets.left = newValue }
get { return textInsets.left }
}
@IBInspectable
var rightTextInset: CGFloat {
set { textInsets.right = newValue }
get { return textInsets.right }
}
@IBInspectable
var topTextInset: CGFloat {
set { textInsets.top = newValue }
get { return textInsets.top }
}
@IBInspectable
var bottomTextInset: CGFloat {
set { textInsets.bottom = newValue }
get { return textInsets.bottom }
}
}
