.m は C + objc, .mm は C++ + objc

object 識別子は id

isa フィールドで introspection

[receiver message]

[myRect setOrigin:30.0 :50.0];

[myRect setWidth:10.0 height:15.0];

[receiver makeGroup:group, memberOne, memberTwo, memberThree];

[myRect setPrimaryColor:[otherRect primaryColor]];

id aClass = [anObject class];

Class aClass = [anObject class];

init

id myRect;

myRect = [Rectangle alloc];

myRect = [[Rectangle alloc] init];

if ( [anObject isKindOfClass:[Rectangle class]] )

class def

@interface ClassName :ItsSuperclass

{

instance variable declarations

}

method declarations

@end

instance vars

float width;

float height;

BOOL filled;

NSColor *fillColor;

class method

alloc;

instance method

- (void)display;
- (void)setRadius:(float)aRadius;

if type is missing, it is treated as 'id'

var args

- makeGroup:group, ...;

use import instead of include. import includes the source only once.

#import "Rectangle.h"

tell compiler that the source uses classes outside of class hierarchy

@class Rectangle, Circle;

class implementation

@implementation ClassName :ItsSuperclass

{

instance variable declarations // can be omitted

}

method definitions

@end

#import "ClassName.h"

@implementation ClassName

method definitions

@end

alloc

{

...

}

(BOOL)isfilled

{

...

}

(void)setFilled:(BOOL)flag

{

...

}

@interface Worker :NSObject

{

char *name;

@private

int age;

char *evaluation;

@protected

id job;

float wage;

@public

id boss;

}

NSString literal @"..."

localize しない場合は info.plist に設定

debug image vs release image pjoject -> active release type

derug runs only on dev machines
