在标签及其边框之间添加填充

Question

我的快速应用程序中有一些应该有边框的标签。我在标签上添加了边框，但我想在标签和边框之间留出更多空格。

我该怎么做？

Answer 1

一个简单的解决方案是将标签嵌入视图中，然后将边框添加到此视图，而不是标签本身。我希望这能帮到你。

Answer 2

试试这个：

myLabel.frame.size.width = myLabel.intrinsicContentSize.width + 10
myLabel.frame.size.height = myLabel.intrinsicContentSize.height + 10
myLabel.textAlignment = .center

Answer 3

我这样做了（将文本放在同一位置）

//label position
myLabel.layer.frame.size.width += 10
myLabel.layer.frame.origin.x -= 5
myLabel.textAlignment = .center

//border
myLabel.layer.borderColor = UIColor.systemTeal.cgColor
myLabel.layer.borderWidth = 1.0
label.layer.cornerRadius = 8.0

Answer 4

1.添加这个类

PaddingLabel.swift

import UIKit

class PaddingLabel: UILabel {

    var edgeInset: UIEdgeInsets = .zero

    override func drawText(in rect: CGRect) {
        let insets = UIEdgeInsets.init(top: edgeInset.top, left: edgeInset.left, bottom: edgeInset.bottom, right: edgeInset.right)
        super.drawText(in: rect.inset(by: insets))
    }

    override var intrinsicContentSize: CGSize {
        let size = super.intrinsicContentSize
        return CGSize(width: size.width + edgeInset.left + edgeInset.right, height: size.height + edgeInset.top + edgeInset.bottom)
    }
}

2.将标签的类别更改为 PaddingLabel

3.将此代码添加到您的 ViewController

import UIKit

class LabelViewController: UIViewController {

    @IBOutlet weak var label: PaddingLabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        //Setting the border
        label.layer.borderWidth = 1
        label.layer.borderColor = UIColor.blue.cgColor
        
        //Setting the round (optional)
        label.layer.masksToBounds = true
        label.layer.cornerRadius = label.frame.height / 2
    
        //Setting the padding label
        label.edgeInset = UIEdgeInsets(top: 5, left: 10, bottom: 5, right: 10)
    
    }
}

结果
