iphone - 将 kABPersonPhoneProperty 转换为阿拉伯数字

Question

我正在从电话通讯录中读取电话号码，一些号码以非阿拉伯数字保存在那里，即(١٢٣٤٥٦٧٨٩)我如何将这些号码转换为阿拉伯数字(123456789)

这就是我提取数字的方式

    CFTypeRef phoneProperty = ABRecordCopyValue(record, kABPersonPhoneProperty);
    NSArray *phones = (__bridge_transfer NSArray *)ABMultiValueCopyArrayOfAllValues(phoneProperty);

现在电话包含电话号码作为 NSString 对象

测试:

-(NSString*)arabicToWestern:(NSString)numericString {
   NSMutableString *s = [NSMutableString stringWithString:numericString];
   NSString *arabic = @"١٢٣٤٥٦٧٨٩";
   NSString *western = @"123456789";
   for (uint i = 0; i<arabic.length; i++) {
      NSString *a = [arabic substringWithRange:NSMakeRange(i, 1)];
      NSString *w = [western substringWithRange:NSMakeRange(i, 1)];
      [s replaceOccurrencesOfString:a withString:w 
                            options:NSCaseInsensitiveSearch
                              range:NSMakeRange(0, s.length)];
   }
   return [NSString stringWithString:s];
}
