swift 如何在Swift中为UITextField设置填充。

Posted 2021-05-19

extension UITextField {
    func setLeftPadding(_ padding: CGFloat) {
        let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: padding, height: self.frame.height))
        self.leftView = paddingView
        self.leftViewMode = .always
    }
}

USAGE:

myTextField.setLeftPadding(13)
