iOS開發，系統內建表情的擷取

//將數字轉為#define EMOJI_CODE_TO_SYMBOL(x) ((((0x808080F0 | (x & 0x3F000) >> 4) | (x & 0xFC0) << 10) | (x & 0x1C0000) << 18) | (x & 0x3F) << 24);

- (void)viewDidLoad {    [super viewDidLoad];    //單獨調用    int sym = EMOJI_CODE_TO_SYMBOL(0x1F600);    NSString *emoT = [[NSString alloc] initWithBytes:&sym length:sizeof(sym) encoding:NSUTF8StringEncoding];    NSLog(@arr==%@,emoT);    //擷取數組    NSArray *arrEmotion = [self defaultEmoticons];    for (NSString *str in arrEmotion) {        NSLog(@===%@,str);    }}

//擷取預設表情數組- (NSArray *)defaultEmoticons {    NSMutableArray *array = [NSMutableArray new];    for (int i=0x1F600; i<=0x1F64F; i++) {        if (i < 0x1F641 || i > 0x1F644) {            int sym = EMOJI_CODE_TO_SYMBOL(i);            NSString *emoT = [[NSString alloc] initWithBytes:&sym length:sizeof(sym) encoding:NSUTF8StringEncoding];            [array addObject:emoT];        }    }    return array;}
