[Objective C] 15 NSDictionary

NSDictionary
java의 map.
NSMutableDictionary 도 소트는 안되는 듯.

main.m

#import <Foundation/NSString.h> #import <Foundation/NSAutoreleasePool.h> #import <Foundation/NSDictionary.h> #import <Foundation/NSEnumerator.h> #import <Foundation/Foundation.h> #import <stdio.h> void print( NSDictionary *map ) {     NSEnumerator *enumerator = [map keyEnumerator];     id key;     while ( key = [enumerator nextObject] ) {         printf( "%s => %s\n",                 [[key description] cString],                 [[[map objectForKey: key] description] cString] );     } } int main( int argc, const char *argv[] ) {     NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];     NSDictionary *dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:         @"one", [NSNumber numberWithInt: 1],         @"two", [NSNumber numberWithInt: 2],         @"three", [NSNumber numberWithInt: 3],         nil];     NSMutableDictionary *mutable = [[NSMutableDictionary alloc] init];     // print dictionary     printf( "----static dictionary\n" );     print( dictionary );     // add objects     [mutable setObject: @"Tom" forKey: @"tom@jones.com"];     [mutable setObject: @"Bob" forKey: @"bob@dole.com" ];     // print mutable dictionary     printf( "----mutable dictionary\n" );     print( mutable );     // free memory     [dictionary release];     [mutable release];     [pool release];     system("PAUSE");     return 0; }

결과

----static dictionary 1 => one 3 => three 2 => two ----mutable dictionary bob@dole.com => Bob tom@jones.com => Tom 계속하려면 아무 키나 누르십시오 . . .

- Foundation Framework classes의 references만 찾아봐도 양이 상당할 듯...ㅎㄷㄷ
