Call methods on Unity3D straight from your Objective-C code

The problem

So you want to trigger functionality in your Unity3D scene straight from your native Objective-C code?  For example you have different scenes, and you want a regular iOS component (e.g. UIButton) to trigger a new scene. It takes some work, but it is doable.

tl;dr

Read it … bitch 🙂

The solution

Unity exposes a way to call code in your Unity3D project (normally this will be javascript or C#).  There are 3 components you need to get in place.

  1. Have a Unity3D scene
  2. Have a Unity3D script
  3. Have an Objective-C class

The way it works is that you can bridge your code from Objective-C to C# or Javascript in Unity3D with the ‘UnitySendMessage’ method.

Add Unity3D in a native iOS application

I HAVE CREATED A NEW WAY TO INTEGRATE UNITY WITHIN AN EXISTING IOS APP. YOU CAN FIND THE POST HERE.

The problem

For a project I need to implement an augmented reality feature inside a native iOS application.  We chose to go with Unity3D and Vuforia to do the augmented reality bit, as it’s free and lots of people are saying it’s the best solution. The only problem when working with Unity3D is that the exported iOS project is not easy to implement in an existing project as we only need Unity3D for 2 views inside a project with some dozen other native UIViews.

National Geographic UIKit Animation transition demo

This afternoon Thomas Degry (one of my students, www.devine.be) asked how he could program the neat little effect they use in the National Parks iPad app made for National Geographic. If you want to see the effect yourself, I suggest you download the app to check it out. Just select one of the parcs and then tap on the stats or the weather button. You’ll see a nice transition in which the master view ‘steps’ into the background, while the new content is placed in front of it.

It took me a few minutes of tapping to see how the animation works, so here is how you can mimic the effect. Just play with CALayers and some transformations 🙂

Add CKEditor to CakePHP with model validation

Enumerate fonts on your iOS device

When you work with custom fonts in your iOS projects, you’ll need to find out the correct name for your font.

You can do this by looping though all the font families and then use the font family name to loop through all the fonts that belong to the family.

The following function will take care of this and return you a nice list ordered per font family.

I’ve also created a gist on github You can find it right here.
