ios - NSString to NSNumber ignores initial zeros -

-

i converting nsstring nsnumber. problem if nsstring starts zeros converting nsnumber ignores initial zeros. know initial zeros doesn't mean want keep initial zeros because it's phonenumber in case.

here code:

nslog(@"test1: %@",tempphonenumber); nsnumberformatter *formatter=[[nsnumberformatter alloc] init]; [formatter setnumberstyle:nsnumberformatterdecimalstyle]; nsnumber *temppnonenumbernumber=[formatter numberfromstring:tempphonenumber]; nslog(@"test: %@",temppnonenumbernumber);

if test1: 00966123456789 test: 966123456789

i want both same

nsnumber cannot keep initial zeros.

if want keep zeros, don't convert it nsnumber. phone numbers not numbers, there kept strings.

also note phonenumbers can contain other characters: +, * or #. these characters have special meaning (e.g. + @ beginning means same 00).
