objective c - From string with locale to date on iphone sdk -

i trying find way convert string date given locale identifier. have example italian date (locale: it_it) want convert valid date object.

nsdate *gldatewithstring(nsstring *string, nsstring *localeidentifier) {     [nsdateformatter setdefaultformatterbehavior:nsdateformatterbehavior10_4];     nsdateformatter *formatter = [[nsdateformatter alloc] init];      nslocale *locale = [[nslocale alloc] initwithlocaleidentifier:localeidentifier];     [formatter setlocale:locale];     [locale release];      nsdate *date = [formatter datefromstring:string];     [formatter release];      return date; } 

this code not work, date nil. can't figure out how should use locale setting purpose.

the solution use getobjectvalue:forstring:range:error: method of nsdateformatter , set correct date , time style ad follow:

- (nsdate *)datewithstring:(nsstring *)string locale:(nsstring *)localeidentifier {     nsdateformatter *formatter = [[nsdateformatter alloc] init];     [formatter settimestyle:nsdateformatternostyle];     [formatter setdatestyle:nsdateformattershortstyle];      nslocale *locale = [[nslocale alloc] initwithlocaleidentifier:localeidentifier];     [formatter setlocale:locale];     [locale release];      nsdate *date = nil;     nsrange range = nsmakerange(0, [string length]);     nserror *error = nil;     bool converted = no;     converted = [formatter getobjectvalue:&date forstring:string range:&range error:&error];     [formatter release];      return converted? date : nil; } 

example:

nsstring *italiandate = @"30/10/2010"; nsstring *italianlocale = @"it_it";  nsdate *date = [mycustomformatter datewithstring:italiandate locale:italianlocale];
