How do you grab clicked button's frame?

[robmontesinos]

I've implemented BMB successfully in my app. What I'd like to do is capture the clicked button's frame as the origination for an animated view controller transition.

I've implemented BoomDelegate.

func boomMenuButton(_ bmb: BoomMenuButton, didClickBoomButtonOfBuilder builder: BoomButtonBuilder, at index: Int) {
        loggingPrint(bmb.frame)
        loggingPrint(builder.imageFrame)
        
        let rect = builder.imageFrame
        let currentRect = convert(rect, to: bmb.superview)
        
        loggingPrint(currentRect)
    }
}

This delegate method returns the following in the console:

HeaderView.swift boomMenuButton(:didClickBoomButtonOfBuilder:at:)[315]: (317.0, 8.0, 50.0, 50.0)
HeaderView.swift boomMenuButton(:didClickBoomButtonOfBuilder:at:)[316]: (10.0, 10.0, 30.0, 30.0)
HeaderView.swift boomMenuButton(_:didClickBoomButtonOfBuilder:at:)[317]: (10.0, 10.0, 30.0, 30.0)

This return is not giving me anything useful. Any help would be appreciated. Thank you.

I wound up temporarily solving this situation by exposing BoomMenuButton property "endPositions" by changing private keyword to public. The code below wound up working for me:

    // MARK: - BoomDelegate
    func boomMenuButton(_ bmb: BoomMenuButton, didClickBoomButtonOfBuilder builder: BoomButtonBuilder, at index: Int) {
        let buttonMenuFrame = bmb.frame
        let buttonEndPoint = bmb.endPositions[index]
        let buttonFrame = CGRect(x: buttonEndPoint.x - (0.5 * buttonMenuFrame.width),
                                 y: buttonEndPoint.y - (0.5 * buttonMenuFrame.height - Dimensions.bannerHeight.rawValue),
                                 width: buttonMenuFrame.width,
                                 height: buttonMenuFrame.height)
        
        buttonClickedFrame = buttonFrame
    }

buttonClickedFrame can now be referenced by transition manager.

It would be great if the library also exposed endPositions
