Implementing a method taking a block to use as callback
You can call a block like a regular function:
BOOL finished = ...;if (completion) { completion(finished);}So that means implementing a complete block function using your example would look like this:
+ (void)myMethod:(UIView *)exampleView completion:(void (^)(BOOL finished))completion { if (completion) { completion(finished); }}
If you're specially looking for a doc, to create custom method using blocks, then the following link is the one which explains almost everything about it. :)

I happen to answer quite a same question recently, have a look at this: Declare a block method parameter without using a typedef
