September 7th, 2012 Posted by: - posted under:Tutorials - 6 Comments

Recently I came across an openGL ES 2.0 engine that made setup, displaying and animating of 3D objects a breeze, called NinevehGL.  This 3D engine has many great features including a full multithreading environment, to keep the main run loop free during object rendering,  motion tweening, object groupings, custom lighting, materials and textures, custom shader support,  and native support for augmented reality, just to name a few. Another major benefit is the ability to import both wavefront …

Using Method-Swizzling to help with Test Driven Development

August 8th, 2012 Posted by: - posted under:Articles » Tutorials - 1 Comment

Introduction
In this blog post I will demonstrate how to mock HTTP requests using an Objective-C runtime dynamic method replacement technique known as method swizzling. I will show how this can be used in tandem with some unit test technologies to help with development of iOS web-service client side code.
In this example, the actual work of the HTTP request is embodied in my AsyncURLConnection class. It uses NSURLConnection to perform an NSURLRequest in an asynchronous manner, using completion handler blocks to return …

Disable the iPhone’s Front Camera

August 23rd, 2011 Posted by: - posted under:Tutorials - 4 Comments

Unfortunately the UIImagePickerController class does not have an option to restrict the user from using the front camera. Although you can check the size of the photo after the user is finished, it’s not great user experience to reject it after they go through the entire process of taking a photo.
One option is to …
