如何像口语一样将数字转换为文本？

如果值以百万为单位，那么字符串应该是.. miliion ..thousand ..hundred。 我使用了这段代码，但它显示的是百万值，如何解决这个问题？

  //convert to words
 NSString *wordNumber;
 NSNumber *numberValue = [NSNumber numberWithInt:digit]; //needs to be NSNumber!
 NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
 [numberFormatter setNumberStyle:NSNumberFormatterSpellOutStyle];
  //    [numberFormatter setNumberStyle:@"en_IN"];
 [numberFormatter setLocale:[NSLocale currentLocale]]; // happen by default?
 wordNumber = [numberFormatter stringFromNumber:numberValue];
 NSLog(@"Answer: %@", wordNumber);

这个对我有用。

Code:

#import <Foundation/Foundation.h>

int main(int argc, char *argv[]) {
    @autoreleasepool {
             //convert to words
             NSString *wordNumber;
             NSNumber *numberValue = @6453323; //needs to be NSNumber!
             NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
             [numberFormatter setNumberStyle:NSNumberFormatterSpellOutStyle];
              //    [numberFormatter setNumberStyle:@"en_IN"];
             [numberFormatter setLocale:[NSLocale currentLocale]]; // happen by default?
             wordNumber = [numberFormatter stringFromNumber:numberValue];
             NSLog(@"Answer: %@", wordNumber);
    }
}

Output:
