multi direction in MDCSwipeDirection.h? about mdcswipetochoose

[modocache]

@mez Sure, that sounds like a great idea!

Users should be able to specify which directions they want. For example, the following code would enable swiping left and up:

MDCSwipeToChooseViewOptions *options = [MDCSwipeToChooseViewOptions new];
options.supportedDirections = MDCSwipeDirectionLeft | MDCSwipeDirectionUp;

If supportedDirections is not set explicitly, left and right should be enabled by default.

Sounds like a good plan!

I successfully implemented this functionality
using some code from the @rFlex Pull request.

Now you can detect up down left right directions!

options.allowedDirections = MDCSwipeDirectionUp | MDCSwipeDirectionDown | MDCSwipeDirectionLeft | MDCSwipeDirectionRight;

Check the Example in my fork 👍

For testing the Example

pod 'MDCSwipeToChoose' :git => 'https://github.com/clsource/MDCSwipeToChoose.git'

Thanks for this great library! ❤️

@clsource i actually saw this and forked yours and added some changes so YOUR changes w/ the MDCSwipeToChooseView sample view that comes w/ the project. But anyways, thanks, you saved me lots of time.

It seems my up and down directions are recognized incorrectly. If I do what I do below, a swipe up is recognized as direction down but if I do the reverse, see below it works.

Why does the following NOT work?

        if (translation.y > 0.f) {

            direction = MDCSwipeDirectionUp;

        } else if(translation.y < 0.f) {

            direction = MDCSwipeDirectionDown;
        }

Instead I have to reverse it to the following in order for it to act properly:

        if (translation.y < 0.f) {

            direction = MDCSwipeDirectionUp;

        } else if(translation.y > 0.f) {

            direction = MDCSwipeDirectionDown;
        }

That doesn't make sense, how can translation.y < 0.f be up?

I ended using another solution more flexible.
