如何使UITextField填充

Question

我有一个Swift应用程序。为了进行填充，我编写了以下代码：

class TextField: UITextField {

let padding = UIEdgeInsets(top: 0, left: 15, bottom: 0, right: 5)

override open func textRect(forBounds bounds: CGRect) -> CGRect {
    return UIEdgeInsetsInsetRect(bounds, padding)
}

override open func placeholderRect(forBounds bounds: CGRect) -> CGRect {
    return UIEdgeInsetsInsetRect(bounds, padding)
}

override open func editingRect(forBounds bounds: CGRect) -> CGRect {
    return UIEdgeInsetsInsetRect(bounds, padding)
}

但是今天我将项目转换为Swift 4.2，现在出现错误：

'UIEdgeInsetsInsetRect'已被实例方法'CGRect.inset（by :)'取代

我该如何解决？

Answer 1

替换UIEdgeInsetsInsetRect(bounds, padding)为bounds.inset(by: padding)
