添加空間/填充到UILabel我有一個UILabel我想在頂部和底部添加空間的地方。在約束中使用最小高度我將其修改為：編輯：要做到這一點，我用過： override func drawTextInRect(rect: CGRect) {
var insets: UIEdgeInsets = UIEdgeInsets(top: 0.0, left: 10.0, bottom: 0.0, right: 10.0)
super.drawTextInRect(UIEdgeInsetsInsetRect(rect, insets))
}但我要找到一種不同的方法，因為如果我寫兩行以上的問題是相同的：

import UIKitclass PaddingLabel: UILabel {
@IBInspectable var topInset: CGFloat = 5.0
@IBInspectable var bottomInset: CGFloat = 5.0
@IBInspectable var leftInset: CGFloat = 5.0
@IBInspectable var rightInset: CGFloat = 5.0
override func drawText(in rect: CGRect) {
let insets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
}
override var intrinsicContentSize: CGSize {
get {
var contentSize = super.intrinsicContentSize
contentSize.height += topInset + bottomInset
contentSize.width += leftInset + rightInset return contentSize }
