Previously I mentioned the excellent JSONModel library providing a number of nice features working with JSON data most notably that makes it easy to convert JSON data to Objective-C objects.
Here’s a tutorial submitted by JSONModel developer Marin Todorov that walks through the creation of a couple of simple apps utilizing JSONModel step-by-step.
In the tutorial some of the things you’ll learn are how to:
Apple has done an excellent job with the documenting the Swift programming language and I’ve been asked a couple of times about tutorials and so far by the best are on Apple’s own Swift Programming language page.
Here’s a tutorial from Matthijs Hollemans that takes a different approach to teaching the basics of the Swift programming language guiding you through the creation of a Candy Crush style match 3 game using Sprite Kit.
Yesterday I mentioned a component allowing you to easily replicate the animated view bending effect as seen in the Skype app.
Here’s another project created to show how to replicate the effect of a popular app providing source code example and brief tutorial showing how to recreate the Twitter bird zoom in transition seen when opening the Twitter app from Rounak Jain.
A couple of years ago I mentioned the excellent Objective-C modelling framework Mantle that provides many nice features such as allowing you to quickly return a JSON dictionary representing an object.
Here’s a step-by-step example submitted by Atomic Object that will show you how to create a user model with Mantle to pass to a server.
UIBezierPath allows us to create curved line segments between points, but things get complicated when trying to draw smooth curves between changing sets of points.
Here’s a nice guide submitted by Atomic Object that explains how to create smooth cubic bezier curves neatly through a set of points.
The guide provides to simple methods for interpolating cubic bezier curves using cubic Hermite splines, and Catmull-Rom curves with some easy to follow code examples and no complex math.
