获取当前时间数字转换十六进制数据（0x）

话不多说，直接上码。

NSString*string = [[NSStringalloc]initWithFormat:@"%@",_StartLabel.text];

    NSArray*timeComs = [stringcomponentsSeparatedByString:@":"];

    Bytehour_byte = (Byte)[timeComs.firstObjectintValue];

    Bytemin_byte = (Byte)[timeComs.lastObjectintValue];

    NSDate*currentDate = [NSDatedate];

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

    [dateFormattersetDateFormat:@"HH:mm"];

    NSString*dateString = [dateFormatterstringFromDate:currentDate];

    NSArray* currenttime = [dateStringcomponentsSeparatedByString:@":"];

    Bytecurrent_hour = (Byte)[currenttime.firstObjectintValue];

    Bytecurrent_min  = (Byte)[currenttime.lastObjectintValue];

    ByteB ={01+02+01+hour_byte+min_byte+01+current_hour+current_min};

    Bytesum = ~B+1;

    NSLog(@"        %d",B);

    NSLog(@"        %hhu",sum);

    Bytetable[] = {0xFD,0xFA,0x01,0x02,0x01,hour_byte,min_byte,0X01,0x00,0x00, current_hour,current_min,0x00, sum,0xFD,0xFA};

    for(intj =0; j

        NSLog(@"%02x", table[j]);

    }
