转换NSString-> NSDate？

我需要转换我的NSString到最后一个NSDate，但我有这样做的问题。 如何使用此代码实现相同的function，同时使最终结果为NSDate？

//Date and Format it NSDate *now = [NSDate date]; NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease]; [formatter setDateFormat:@"MM-dd-yyyy"]; NSString *dateString = [formatter stringFromDate:now]; 

谢谢！

编辑：

 //Date and Format it NSDate *now = [NSDate date]; NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease]; [formatter setDateFormat:@"MM-dd-yyyy"]; NSString *dateString = [formatter stringFromDate:now]; NSDate *enddate = [formatter dateFromString:dateString]; [[NSUserDefaults standardUserDefaults] setObject:enddate forKey:@"theDate"];

 NSDate *date = [formatter dateFromString:dateString];
