So the hacking started... Using Blocks in iOS 4: Designing with Blocks. In the first part of this series, we learned how to declare and call basic Objective-C blocks.
The motivation was to understand how to effectively use the new APIs in iOS 4 that take blocks as parameters. In this installment we're going to shift our focus toward writing our own methods that take blocks. By understanding how to use blocks in your own code, you'll have another design technique in your repertoire. And you might just find that blocks make your code easier to read and maintain. ASIHTTPRequest Documentation - All-Seeing Interactive.
