about this item
Suddenly, program optimization is crucial again. Yesterday’s “automatic” increases in computer performance have effectively stopped. iOS devices such as the iPhone, iPad, iPod touch, and Apple TV have dramatically fewer resources: their limited resources must be used as frugally as possible. Now, in Cocoa and Objective-C Performance,Marcel Weiher draws on more than 20 years of experience optimizing software for Apple devices, drilling down to the code level to systematically address optimization of CPU, memory, disk and network I/O and graphics.
The only book focused entirely on Cocoa and Objective-C performance optimization, this book is strongly empirically based, identifying concrete issues that can be discovered via measurement, and then addressed through the application of specific techniques and a deep understanding of proven underlying principles.
Weiher presents insights you won’t find anywhere else – most of which can be easily applied to both Mac and iOS development. He also identifies a series of common pitfalls and misconceptions associated with OS X and iOS performance, revealing why they are wrong, explaining the actual realities, and showing developers how to reflect those realities in more efficient code.
