更改UITextField中的文本布局

您可以订阅自定义TextField：

import UIKit

class CustomTextField: UITextField {

    var inset:CGFloat = 12  // You can set the inset you want

    override func textRect(forBounds bounds: CGRect) -> CGRect {

        return bounds.insetBy(dx: inset, dy: 0)
    }

    override func editingRect(forBounds bounds: CGRect) -> CGRect {

        return bounds.insetBy(dx: inset, dy: 0)
    }

}

结果，您可以看到CustomTextField的插图：
