Every now and then new stuff comes along that makes our lives easier. One of the best things to come to Objective-C is the advent of blocks. Blocks can simplify callbacks, enumeration, and they have huge benefits in terms of multi-threading. At first, blocks will blow your mind. Block syntax is weird, but once you get the hang of em’ they’re actually kinda easy.

- You’re familiar with UIAlertView.
- You have good understanding of the delegate pattern.
- You have at least heard of Blocks in Objective-C.
Have you ever found yourself wanting to present an alertView to the user to get simple yes or no feedback? If you’re anything like me you were very annoyed that you were required to implement the UIAlertView delegate protocol just to handle this simple task.
Is There A Better Way?
