Question

I have a static block variable inside a class. How can I declare a property or an instance selector to return or send that block to a caller?

This is my static block:

static NSResultComparison(^myBlock)(id obj1, id obj2);

Answer 1

It would be best to typedef your block.

//interface.h
typedef NSResultComparison (^ComparisonBlock)(id obj1, id obj2);

@interface ...
...

-(ComparisonBlock) getComparisonBlock;

@end

---

//implementation.m
//Here is your static block implementation
static ComparisonBlock myStaticBlock = ^(id obj1, id obj2)
{
    ...
    return result;
};

@implementation ...

-(ComparisonBlock)getComparisonBlock
{
    return myStaticBlock;
}

@end
