Objective-C @property , @synthesize

@property , @synthesize 를 간단하게 요약해 봅시다.

@interface Fraction : NSObject
{
int numerator;
int denominator;
}

@property int numerator, denominator;

~~~
@end

-------------------------------------------------

@implementation Fraction

@synthesize numerator, denominator;

-------------------------------------------------

myFraction.numerator = 1;
myFraction.denomiator = 3;

요정도 까지..
