3. MVC
3.1 Model
what does your application does?

3.2 View
Show your model

3.3 Controller
How your models show on screen

Controller send message to Model
Controller send message to View(outlet)

View talk to Controller(Tareget)
(Will Did Should Delegate)
View do not own the data they display.
View get data source from Controller (Data at, Count)

Model send Notification & KVO to Controller

4. Language Objective-C
Interface
Spaceship.h
#import "vehicle.h"
#import "Planet.h"

@interface Spaceship: Vehicle
//declaration of public method

@property (nonatomic) double topSpeed;

- (void) orbitPlanet:(Planet *) aPlanet
atAltitude:(double)km;

- (void) setTopSpeed:(double)percentSpeedOfLight;
- (double) topSpeed

@end

Implementation
Spaceship.m
#import "Spaceship.h"

@interface Spaceship()
//declaration of private methods
@property (nonatomic, strong) Wormhole *nearestWormhole;

@end

@implementation Spaceship

@synthesize topSpeed = _topSpeed;
@synthesize nearestWormhole = _nearestWormhole;

- (void) setTopSpeed:(double)speed
{
//
_topSpeed = speed;
}

- (double) topSpeed
{
//
return _topSpeed;
}

- (void)orbitPlanet:(Planet *)aPlanet atAltitude:(double) km
{
//put codes here
double speed = [self topSpeed]; // self.topSpeed
if(speed > MAX_RELATIVE) speed = MAX_RELATIVE;
[[self nearestWormhole] travelToPlanet:aPlanet
atSpeed:speed];
}
@end

@property @sythesize generate getter and setter for us.

All property are zero when object are created.
