我正在寻找可以为 1、2、3 输出上标的 Unicode 或某种方法或字节语言。无论出于何种原因,Unicode 都有 0、4、5、6、7、8、9 的上标,但没有 1、2 , 3.

你能在中做像 HTML 这样的上标NSString吗?

从字符调色板:

¹
SUPERSCRIPT ONE
Unicode: U+00B9, UTF-8: C2 B9

²
SUPERSCRIPT TWO
Unicode: U+00B2, UTF-8: C2 B2

³
SUPERSCRIPT THREE
Unicode: U+00B3, UTF-8: C2 B3

要使它们进入NSStrings,您将执行以下操作:

NSString *superscript1 = @"\u00B9";
NSString *superscript2 = @"\u00B2";
NSString *superscript3 = @"\u00B3";

我知道这个问题已经得到解答,但是如果有人想重用我的代码来将标准数字字符串转换为上标,这里就是。

-(NSString *)superScriptOf:(NSString *)inputNumber{

    NSString *outp=@"";
    for (int i =0; i<[inputNumber length]; i++) {
    unichar chara=[inputNumber characterAtIndex:i] ;
    switch (chara) {
        case '1':
            NSLog(@"1");
            outp=[outp stringByAppendingFormat:@"\u00B9"];
            break;
        case '2':
            NSLog(@"2");
            outp=[outp stringByAppendingFormat:@"\u00B2"];
            break;
        case '3':
            NSLog(@"3");
            outp=[outp stringByAppendingFormat:@"\u00B3"];
            break;
        case '4':
            NSLog(@"4");
            outp=[outp stringByAppendingFormat:@"\u2074"];
            break;
        case '5':
            NSLog(@"5");
                            outp=[outp stringByAppendingFormat:@"\u2075"];
            break;
        case '6':
            NSLog(@"6");
                            outp=[outp stringByAppendingFormat:@"\u2076"];
            break;
        case '7':
            NSLog(@"7");
            outp=[outp stringByAppendingFormat:@"\u2077"];
            break;
        case '8':
            NSLog(@"8");
            outp=[outp stringByAppendingFormat:@"\u2078"];
            break;
        case '9':
            NSLog(@"9");
            outp=[outp stringByAppendingFormat:@"\u2079"];
            break;
        case '0':
            NSLog(@"0");
            outp=[outp stringByAppendingFormat:@"\u2070"];
            break;
        default:
            break;
    }
}
return outp;   
}

给定输入的数字字符串,它只返回等效的上标字符串。

编辑(感谢 jrturton):

-(NSString *)superScriptOf:(NSString *)inputNumber{

    NSString *outp=@"";
    unichar superScripts[] = {0x2070, 0x00B9, 0x00B2,0x00B3,0x2074,0x2075,0x2076,0x2077,0x2078,0x2079};

    for (int i =0; i<[inputNumber length]; i++) {

        NSInteger x =[[inputNumber substringWithRange:NSMakeRange(i, 1)]  integerValue];
        outp=[outp stringByAppendingFormat:@"%C", superScripts[x]];

    }

    return outp;   
}
