IOS - 统一code Unsign [英] IOS - Unicode Unsign

问题描述

我用C＃编写一个函数，我想将其转换为目标c。怎么办呢？

 公共静态字符串的Uni codeUnSign（字符串s）
{
    常量字符串单字符= \"àáảãạâầấẩẫậăằắẳẵặèéẻẽẹêềếểễệđìíỉĩịòóỏõọôồốổỗộơờớởỡợùúủũụưừứửữựỳýỷỹỵÀÁẢÃẠÂẦẤẨẪẬĂẰẮẲẴẶÈÉẺẼẸÊỀẾỂỄỆĐÌÍỈĨỊÒÓỎÕỌÔỒỐỔỖỘƠỜỚỞỠỢÙÚỦŨỤƯỪỨỬỮỰỲÝỶỸỴÂĂĐÔƠƯ\";
    常量字符串koDauChars = \"aaaaaaaaaaaaaaaaaeeeeeeeeeeediiiiiooooooooooooooooouuuuuuuuuuuyyyyyAAAAAAAAAAAAAAAAAEEEEEEEEEEEDIIIOOOOOOOOOOOOOOOOOOOUUUUUUUUUUUYYYYYAADOOU\";    如果（string.IsNullOrEmpty（多个））
    {
        返回S;
    }    字符串retVal的=的String.Empty;
    的for（int i = 0; I＆LT; s.Length;我++）
    {
        INT POS = uniChars.IndexOf（S [I]的ToString（））;
        如果（POS＆GT; = 0）
            retVal的+ = koDauChars [POS]
        其他
            retVal的+ = S [I]
    }
    返回retVal的;
}
 

解决方案

您可以使用的CoreFoundation CFStringTransform 函数做几乎所有的转换，从你的清单。只有DJ和DJ已被另案处理：

 的NSString *统一codeUnsign（的NSString * S）
{
    *的NSMutableString结果= ​​[S mutableCopy]
    //如果使用ARC编译__bridge只要求：
    CFStringTransform（（__桥CFMutableStringRef）结果，NULL，kCFStringTransformStripCombiningMarks，否）;    [结果rep​​laceOccurrencesOfString：@DJwithString：@D选项：0范围：NSMakeRange（0，[结果长度]）];
    [结果rep​​laceOccurrencesOfString：@DJwithString：@D选项：0范围：NSMakeRange（0，[结果长度]）];    返回结果;
}
 

例如：

 的NSString *输入= @世界，你好 - ếểễệđìíỉĩịòó！;
* NSString的输出=统一codeUnsign（输入）;
的NSLog（@％@，输出）;
//输出信息：Hello World！ -  eeeediiiiioo
 

I have a function written in C#, i want to convert it to objective-c. How to do it?

public static string UnicodeUnSign(string s)
{
    const string uniChars = "àáảãạâầấẩẫậăằắẳẵặèéẻẽẹêềếểễệđìíỉĩịòóỏõọôồốổỗộơờớởỡợùúủũụưừứửữựỳýỷỹỵÀÁẢÃẠÂẦẤẨẪẬĂẰẮẲẴẶÈÉẺẼẸÊỀẾỂỄỆĐÌÍỈĨỊÒÓỎÕỌÔỒỐỔỖỘƠỜỚỞỠỢÙÚỦŨỤƯỪỨỬỮỰỲÝỶỸỴÂĂĐÔƠƯ";
    const string koDauChars = "aaaaaaaaaaaaaaaaaeeeeeeeeeeediiiiiooooooooooooooooouuuuuuuuuuuyyyyyAAAAAAAAAAAAAAAAAEEEEEEEEEEEDIIIOOOOOOOOOOOOOOOOOOOUUUUUUUUUUUYYYYYAADOOU";

    if (string.IsNullOrEmpty(s))
    {
        return s;
    }

    string retVal = String.Empty;
    for (int i = 0; i < s.Length; i++)
    {
        int pos = uniChars.IndexOf(s[i].ToString());
        if (pos >= 0)
            retVal += koDauChars[pos];
        else
            retVal += s[i];
    }
    return retVal;
}

解决方案

You could use the CoreFoundation CFStringTransform function which does almost all transformations from your list. Only "đ" and "Đ" have to be handled separately:

NSString *UnicodeUnsign(NSString *s)
{
    NSMutableString *result = [s mutableCopy];
    // __bridge only required if you compile with ARC:
    CFStringTransform((__bridge CFMutableStringRef)result, NULL, kCFStringTransformStripCombiningMarks, NO);

    [result replaceOccurrencesOfString:@"đ" withString:@"d" options:0 range:NSMakeRange(0, [result length])];
    [result replaceOccurrencesOfString:@"Đ" withString:@"D" options:0 range:NSMakeRange(0, [result length])];

    return result;
}

Example:

NSString *input = @"Hễllö Wõrld! - ếểễệđìíỉĩịòó";
NSString *output = UnicodeUnsign(input);
NSLog(@"%@", output);
// Output: Hello World! - eeeediiiiioo
