在目标c中将数字转换为单词

Question

我需要写一些数字:1> yek

123> yeksad o bist o se

1,123> yek hezar o yeksad o bist o se

3,002,001> se milion o do hezar o yek ...

我,在目标c的初学者:)

我用c写它但我想把它转换成obj_c!我怎样才能做到这一点？

像这样的东西:

const char  *yekan[10]={"","yek","do","se","chahar","panj","shesh","haft","hasht","noh"};
char ary[9]={'0','0','0','0','0','0','0','0','0'};

// get a number from user & converting it to string

// user number: 123 > the number in ary:000 000 123) 

// '3' => 3

m=(int) ary[8]; 
m=m-'0'; 

if (j==3)   { printf(" %s ",yekan[m]);} // yekan[3] = se 

output: se

谢谢.

NSNumberFormatter类具有将转换数转换为单词的内置功能:

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle: NSNumberFormatterSpellOutStyle];
[formatter setLocale:...]; // Set locale if you want to use something other then the current one
NSString* numberString = [formatter stringFromNumber:[NSNumber numberWithInt: 100]];
