如何将字母数字字符串转换为NUMBER字符串或NUMBER？

Question

我想将字母数字字符串转换为数字。字母数字字符串包含数字数字集[0-9]，大写字母集[AZ]和小写字母集[az]分别为数字[00-09]，[10-35]和[36-62]。

如果字母是＆＃39; y＆＃39;然后号码将是＆＃39; 61＆＃39;或者这封信是＆＃39; C＆＃39;然后号码将是＆＃39; 12＆＃39;或者数字是＆＃39; 6＆＃39;那么数字就是06＆＃39;

例如：

字母数字字符串：＆＃34; yc69CJjVvf＆＃34;

NUMBER：61380609121945315841

Answer 1

创建plist，您必须手动输入数字集[0-9]，大写字母集[A-Z]和小写字母集[a-z]的数据。

见下图。

并创建一个for循环，你必须传递alpha bate值。你将获得该数字。

    NSString *path = [[NSBundle mainBundle] pathForResource:
                      @"YourPlistName" ofType:@"plist"];

    NSMutableArray *arrData = [[NSMutableArray alloc] initWithContentsOfFile:path];
    NSMutableArray *arrCode=[arrData valueForKey:@"code"];
    NSMutableArray *arrname=[arrData valueForKey:@"name"];
        NSString *code = [[NSString alloc] init];


    for (int i=0;i<[arrname count];i++)
    {

        if ([[arrname objectAtIndex:i] isEqualToString:StrAplahbates])//StrAplahbates is the string for which you want number value.
        {
            [code appendFormat:@"%@",arrCode [i]];



        }
    }

您可以使用Character-＆gt; Number AND Number-＆gt; Character创建NSMutableDictionary，然后您可以浏览字符串并转换字符串， 例如：

NSMutableDictionary *stringToNumbersDictionary = [[NSMutableDictionary alloc] init];
NSMutableDictionary *numberToStringDIctionary = [[NSMutableDictionary alloc] init];
for(int i = 0;i <= 9; i++) {
    NSString *keyWithZero = [NSString stringWithFormat:@"0%d",i];
    NSString *keyWithoutZero = [NSString stringWithFormat:@"%d",i];

    // So you can look up with 06 and 6 to get the number-string
    [stringToNumbersDictionary setObject:keyWithZero forKey:keyWithoutZero];
    [numberToStringDIctionary setObject:keyWithoutZero forKey:keyWithZero];
}

// from ASCII A to ASCII Z
for(int i = 65;i <= 90;i++) {
    NSString *key = [NSString stringWithFormat:@"%c",i];
    NSString *numberKey = [NSString stringWithFormat:@"%d",i];

    [stringToNumbersDictionary setObject:numberKey forKey:key];
    [numberToStringDIctionary setObject:key forKey:numberKey];
}

// from ASCII a to ASCII z
for(int i = 97;i <= 122;i++) {
    NSString *key = [NSString stringWithFormat:@"%c",i];
    NSString *numberKey = [NSString stringWithFormat:@"%d",i];

    [stringToNumbersDictionary setObject:numberKey forKey:key];
    [numberToStringDIctionary setObject:key forKey:numberKey];
}

要将字符串转换为数字字符串，您可以使用

- (NSString *)numberStringWithString:(NSString *)string {
    NSMutableString *result = [[NSMutableString alloc] init];
    for(NSInteger index = 0;index < string.length;index++) {
        unichar c = [string characterAtIndex:index];
        NSString *key = [NSString stringWithFormat:@"%c",c];
        [result appendString:stringToNumbersDictionary[key]];
    }
    return result;
}

并将其转换回来

- (NSString *)stringWithNumberString:(NSString *)numberString {
    NSMutableString *result = [[NSMutableString alloc] init];
    for(NSInteger index = 0;index < numberString.length;index+=2) {
        NSString *key = [numberString substringWithRange:NSMakeRange(index, 2)];
        [result appendString:numberToStringDIctionary[key]];
    }
    return result;
}

通过char转到字符串，如果char是符号转换为数字字符串，如果char是数字而不是格式（“0％d”）并将结果累加到一个字符串而不是转换为数字。
