Best way to define private methods for a class in Objective-C

Question

I just started programming Objective-C and, having a background in Java, wonder how people writing Objective-C programs deal with private methods.

I understand there

Answer 1

You could use blocks?

@implementation MyClass

id (^createTheObject)() = ^(){ return [[NSObject alloc] init];};

NSInteger (^addEm)(NSInteger, NSInteger) =
^(NSInteger a, NSInteger b)
{
    return a + b;
};

//public methods, etc.

- (NSObject) thePublicOne
{
    return createTheObject();
}

@end

I'm aware this is an old question, but it's one of the first I found when I was looking for an answer to this very question. I haven't seen this solution discussed anywhere else, so let me know if there's something foolish about doing this.
