Know Your Objective-C Blocks

Bryan Klimt of Parse wrote up a nice and short quiz to test your knowledge of Objective-C blocks. Given the confusion that blocks can cause for even the smart iOS developers, it’s a good check to make sure you’re using them correctly. Bottom line: using ARC helps make the rules more clear.

I missed one of the questions myself. But in my defense, it’s because I’ve been using ARC exclusively and forgot the subtle rules of the “ancient ways”. :)
