Here’s a tutorial submitted by Nirav Bhatt demonstrating step-by-step how to create a video chat app. The tutorial uses OpenTok platform for the face-to-face video chat, and Parse for the back-end.
The tutorial is very complete (6000+ words!) and contains features such as a lobby displaying nearby users, and the ability to create and receive (or decline) calls.
Yesterday I mentioned a project providing a native Mac alternative to AutoInjest.java for downloading iTunes Connect reports.
Here’s a submission from Oliver Michalak of a project called BOMAAB that provides a set of scripts to enable downloading of your App Store sales data, and visualize it within Panic’s Status Board App.
Previously I mentioned a tutorial on how to make smooth lines using Cocos2D inspired by the iPad Paper app.
Heres tutorial on capturing, and drawing smooth lines and curves from Jason Harwig using UIKit.
The tutorial goes through the process of capturing the signature accurately using UIPanGestureRecognizer, drawing quadratic bezier curves between the points to smooth out the signature, and varying width using velocity and tessellation for the Paper app style widening effect.
Last week I mentioned an excellent tutorial showing how to create a Labyrinth style game using UIKit with the Xcode Storyboard tool as a level editor.
Here’s another interesting tutorial on game development using UIKit by Marin Todorov.
In the tutorial you’ll make a great looking word game with a number of cool features such as:
- Particle effects
- Smooth dragging with graphical effects
- Using fonts
I’ve mentioned a number of tutorials on how to use game engines to develop games such as Cocos2D, but none without using a game engine other than a mention of the GeekGameBoard board game source examples.
Here’s something different – a tutorial from Kryzystof Zablocki explaining how one can create a simple ball rolling through a labyrinth style game using the Xcode Storyboard tool/Interface Builder as the level builder, UIKIt for the graphics, and you’ll use Chipmunk for the physics.
