objective c - Get Speed of UISwipeGestureRecognizer - Custom Gesture Recogniser? -

I have an app that plays video I want to control the video by gesture i. Swipe left-to-right-to-left-right-for-right swipe

, but it was when this project was but there was no idea. Now I sit down and sign it that I do not know.

The respondent said that I may need to create a custom gesture identifier to achieve the speed of the blow, I want to speed up the speed of the video.

Any ideas how would I go about it?

I have never created or configured a gesture identifier before, so I do not know how to go about it?

What I really want is a way of handling start and end methods, I think I can get a timer running between two and do the work of X end and expert. To calculate Y, y will help by any help, code-samples and preferences.

Cheers

One way to touch time difference and and touched and . Using these two numbers, you can calculate "pixels per second", or similar. Then you can use the magnitude of the result to act as a coefficient of motion of the video.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
