Swift - UITextField 填充隐藏清除按钮

Question

我创建了一个特殊的文本字段，其右侧有一个填充(我使用的是 RTL 语言)。它工作得很好，除了它隐藏了清除按钮。有什么想法可以在填充 View 顶部呈现清晰的按钮吗？

class PaddedTextField: UITextField {

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

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

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

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

您无法直接访问清除按钮，但可以设置其框架和原点:

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