OPApplePayButton

@objc
public class OPApplePayButton : UIControl

Convenience control that wraps Apple’s PKPaymentButton

It is possible to use Apple’s PKPaymentButton instead of this class if desired. This control provides all styling and customization options provided by PKPaymentButton but also adds some extra functionality:

  • Optional use of onClick property for simpler handling of touch events (UIControl.addTarget(...) is also supported)

  • Ability to update button visuals after view creation (see updateButton)

    Important

    The default height of this view matches the intrinsic height of PKPaymentButton. If constraints or other factors cause this view’s height to expand beyond the intrinsic size, the PKPaymentButton will be centered vertically within this view.

  • Initializes this control with default values of PKPaymentButtonStyle.black, PKPaymentButtonType.checkout and a corner radius of 8

    Declaration

    Swift

    public convenience init()

  • Initializes this control with default values of PKPaymentButtonStyle.black, PKPaymentButtonType.checkout and a corner radius of 8

    Declaration

    Swift

    public override init(frame: CGRect)

    Parameters

    frame

    The frame to use for this control

  • Inititalizes this control with the given type, style, and corner radius

    Declaration

    Swift

    @objc
public convenience init(
    type: PKPaymentButtonType,
    style: PKPaymentButtonStyle,
    cornerRadius: CGFloat
)

    Parameters

    type

    The type of button to display
    style

    The style to use for the button
    cornerRadius

    The corner radius of the button

  • Inititalizes this control with the given frame, type, style, and corner radius

    Declaration

    Swift

    @objc
public init(
    frame: CGRect,
    type: PKPaymentButtonType,
    style: PKPaymentButtonStyle,
    cornerRadius: CGFloat
)

    Parameters

    frame

    The frame to use for this control
    type

    The type of button to display
    style

    The style to use for the button
    cornerRadius

    The corner radius of the button

  • Click handler to handle click events. It is also possible to handle click events using UIControl.addTarget(...)

    Declaration

    Swift

    @objc
public var onClick: (() -> Void)?

  • Whether or not the button is enabled

    Declaration

    Swift

    public override var isEnabled: Bool { get set }

  • Whether or not user events are enabled or ignored and removed from the event queue

    Declaration

    Swift

    public override var isUserInteractionEnabled: Bool { get set }

  • Whether or not the button is highlighted

    Declaration

    Swift

    public override var isHighlighted: Bool { get set }

  • Updates the button with the given type, style, and corner radius

    Important

    Because Apple does not provide a way to update the button type or style after creation, this method removes the current PKPaymentButton instance from this view and then creates and attaches a new instance. If only the corner radius needs to be udpated use updateCornerRadius(...) because that does not require the underlying button to be recreated.

    Declaration

    Swift

    @objc
public func updateButton(
    type: PKPaymentButtonType,
    style: PKPaymentButtonStyle,
    cornerRadius: CGFloat
)

  • Updates the corner radius of the button

    Declaration

    Swift

    @objc
public func updateCornerRadius(cornerRadius: CGFloat)
