更改UITextfield输入的宽度

Question

Is there a way to change the input size of my UITextield so it doesn't overlap with my "vergessen"-Button?

The Textfield is a simple TextfieldView with a width of 315. I added the "Vergessen?" Button programmatically with the code down below.

func createForgetButton () {
    let button = UIButton(type: .system)
    button.setTitle("Vergessen?", for: .normal)
    button.addTarget(self, action: #selector(self.vergessenTapped(_:)), for: .touchUpInside)
    button.titleLabel?.font = UIFont(name: "Avenir Next", size: 19.0)
    passwordTextField.rightView = button
    passwordTextField.rightViewMode = .unlessEditing
}

Use the following custom class for the field. Then update .rightPadding field in IB or in the code to match the width of the button you have on the right.

/**
 * Text field with some changes according to design
 *
 * - author: Alexander Volkov
 * - version: 1.0
 */
@IBDesignable public class CustomTextField: UITextField {

    /// the left padding
    @IBInspectable public var leftPadding: CGFloat = 0 { didSet { self.setNeedsLayout() } }

    /// the right padding
    @IBInspectable public var rightPadding: CGFloat = 0 { didSet { self.setNeedsLayout() } }

    /// Text rectangle
    ///
    /// - Parameter bounds: the bounds
    /// - Returns: the rectangle
    override public func textRect(forBounds bounds: CGRect) -> CGRect {
        let originalRect: CGRect = super.editingRect(forBounds: bounds)
        return CGRect(x: originalRect.origin.x + leftPadding, y: originalRect.origin.y, width: originalRect.size.width - leftPadding - rightPadding, height: originalRect.size.height)
    }

    /// Editing rectangle
    ///
    /// - Parameter bounds: the bounds
    /// - Returns: the rectangle
    override public func editingRect(forBounds bounds: CGRect) -> CGRect {
        let originalRect: CGRect = super.editingRect(forBounds: bounds)
        return CGRect(x: originalRect.origin.x + leftPadding, y: originalRect.origin.y, width: originalRect.size.width - leftPadding - rightPadding, height: originalRect.size.height)
    }
}
