Question

If I have a class function which returns a block do I need to do anything in terms of memory management for the block?

typedef BOOL (^Block)(ParamType* param);


+ (Block) makeBlock: (SeedParamType* seed)
{
    return ^BOOL (ParamType* param)
    {
        // do something with seed
        return someBoolVal;
    };
}


@interface SomeClass() 
@property (copy, nonatomic) Block                 theBlock;
@end

Do I need to do anything like explicitly in terms of memory management, or will ARC deal with everything in this situation?

Thanks

With ARC, you’ll be fine with that. There is enough information there for it to know how to manage it.

Syntax is a bit wrong though, it should be:

+ (Block) makeBlock: (SeedParamType*) seed
{
    return ^BOOL (ParamType* param)
    {
        // do something with seed
        return someBoolVal;
    };
}
