Learn Objective C(2)Learn Objective-C in Day 6 - 4 ~ 6

Car Example
Command-N (File ----> New File) ----> Cocoa Class under Mac OS X and select Objective-C
Name the class as SimpleCar and make it inherent from NSObject.

Interface and Implementation Coding
#import <Foundation/Foundation.h>

@interface SimpleCar : NSObject   

     @property (weak, nonatomic) NSString *make;   

     @property (weak, nonatomic) NSString *model;   

     @property (weak, nonatomic) NSNumber *vin;

      -(void) setMake:(NSString*)newMake      

                     andModel:(NSString*)newModel;
@end

That is the interface.

#import "SimpleCar.h"

@implementation SimpleCar

       @synthesize make, model, vin;

       -(void) setMake:(NSString *)newMake      

              andModel:(NSString *)newModel{   

                   [selfsetMake: newMake];   

                   [selfsetModel: newModel];

       }
@end

Here is the implementation. @properties and @synthesize make it easy to do something like getter and setter.
