转换NSString-> NSDate？

Question

我需要将我的NSString最终转换为NSDate，但我遇到问题。在使最终结果成为NSDate的同时，如何使用此代码实现相同的功能？

//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！

    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];
