Use Categories:

Foo.h

@interface Foo : NSObject
// all your properties
// all your public methods
@end

Foo.m

#import "Foo-Bar.h"
@implementation Foo
// public method implementation
@end

Foo-Bar.h

#import "Foo.h"
@interface Foo (Bar)
// private method interfaces
@end

Foo-Bar.m

#import "Foo-Bar.h"
@implementation Foo (Bar)
// private method implementation
@end

In your implementation for Foo, you can now access any of the methods defined in Foo (Bar)

Keep in mind that all your properties and ivars must be defined in Foo

You can continue to do this eg. Foo (Duck)

Another option is to put

#pragma mark - Some title

in your code. You can then use the Jump bar (at the top of the file editor) to group your methods
