CocoaConf Columbus 2012 Presentations:
Embracing OCUnit
Writing understandable, maintainable unit tests is never easy. This is especially true for OS X and iOS development, where the Xcode tool support is still fairly primitive. OCUnit is a standard xUnit framework integrated into Apple's Xcode environment. This session is designed to help developers learn various techniques for writing and maintaining quality OCUnit tests. Topics include writing "parameterized" test cases (a.k.a. data-driven), testing concurrent code using "latches" (coordinate a deterministic dance between the test thread and background threads), writing mini-test harnesses based on "parameterized" test cases, and various other OCUnit and Xcode tips and tricks.
View DetailsVisualize Your Data With Core Animation
Core Animation is a fantastic animation framework. Come to this session to learn how to build an interactive, animatable pie chart using the Core Animation framework. We will look at how to use CAShapeLayer, CATextLayer and CADisplayLink objects to build the custom chart. These same techniques can also be applied to other types of data visualizations.
