Using MVC to Understand ASP.NET, iOS, Android and Hybrid Development

Model–view–controller (MVC) is a software architecture pattern which separates the representation of information from the user's interaction with it.[1][2] The model consists of application data, business rules, logic, and functions. A view can be any output representation of data, such as a chart or a diagram. Multiple views of the same data are possible, such as a bar chart for management and a tabular view for accountants. The controller mediates input, converting it to commands for the model or view.

iOS 6 and auto-rotation tip

iOS 6 and auto-rotation tip

Upgrading an old app (and I mean *old* - code is checking for to see if we have the new iOS 3!) and ran into some frustration with rotation that the blog posts I read weren't answering. This app is limited (client budget prevented much that I'd like to have done) and the whole app [...]

Smooth Freehand Drawing on iOS

This tutorial will teach you how to implement an advanced drawing algorithm for smooth, freehand drawing on iOS devices. Read on!

Theoretical Overview

Touch is the primary way a user will interact with iOS devices. One of the most natural and obvious functionalities these devices are expected to provide is allowing the user to draw on the screen with their finger. There are many freehand drawing and note-taking apps currently in the App Store, and many companies even ask customers to sign an iDevice when making purchases. How do these applications actually work? Let's stop and think for a minute about what's going on "under the hood".

When a user scrolls a table view, pinches to enlarge a picture, or draws a curve in a painting app, the device display is rapidly updating (say, 60 times a second) and the application run-loop is constantly sampling the location of the user's finger(s). During this process the "analog" input of a finger dragging across the screen must be converted to a digital set of points on the display, and this conversion process can pose significant challenges. In the context of our painting app, we have a "data-fitting" problem on our hands. As the user scribbles away merrily on the device, the programmer essentially must interpolate missing analog information ("connect-the-dots") that has been lost among the sampled touch points that iOS reported to us. Further, this interpolation must occur in such a way that the result is a stroke that appears continuous, natural, and smooth to the end user, as if he had been sketching with a pen on a notepad made of paper.
