它是一个简单的程序：

二进制到字符串转换器

我对编程还是有点陌生​​，我非常感谢您的帮助

我只需要一个在 Xcode 中编译和运行的小脚本

程序所要做的就是转换一个二进制字符串并显示隐藏的单词/消息。这就是全部

像例如

0110001001110010011010010110000101101110001100010011001000110011 == “Brian123”

干得好

NSString *str = @"01100010 01110010 01101001 01100001 01101110 00110001 00110010 00110011";
NSString *str2 = stringFromBinString(str);
NSLog(@"%@",str2); // brian123

这是可以转换的功能

// Function that converts
NSString* stringFromBinString(NSString* binString) {
    NSArray *tokens = [binString componentsSeparatedByString:@" "];
    char *chars = malloc(sizeof(char) * ([tokens count] + 1));

    for (int i = 0; i < [tokens count]; i++) {
        const char *token_c = [[tokens objectAtIndex:i] cStringUsingEncoding:NSUTF8StringEncoding];
        char val = (char)strtol(token_c, NULL, 2);
        chars[i] = val;
    }
    chars[[tokens count]] = 0;
    NSString *result = [NSString stringWithCString:chars
                                          encoding:NSUTF8StringEncoding];

    free(chars);
    return result;
}
