Creating a custom method with completion block

Question

Implementing a method taking a block to use as callback

I couldn't find any clear explanation about how to implement a method that executes a completion block.

I know that NSOperation can be subclasses and used with calling setCompletionBlock: . Anyone knows if this is possible just by implementing in the m. file?

Solution

You may not believe it, but there is a Code Samurai Article which covers the exact ground of your question! About a third of the way down, they subclass NSOperation with an example completion block.

I saw that article but if you read my question, I was asking about a pure implementation way of doing it. But still thank you!
