iphone SDK: How to implement a modal date picker?

How can I implement a modal date picker?

What I want to happen is when the user enters a text field, a new view is created that has the date picker on it. From there, t

Simpler working solution:

In your .h:

@property (nonatomic,strong) IBOutlet UIDatePicker *datePicker;
@property (weak, nonatomic) IBOutlet UITextField *historyDateSelect;
@property (nonatomic, retain) UIToolbar *dateToolbar;

In your .m:

- (void)viewDidLoad
{
    [super viewDidLoad];


    self.datePicker = [[UIDatePicker alloc]init];
    [self.datePicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged];


    UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:nil action:nil];    
    [toolbar setItems:[NSArray arrayWithObject:doneButton]];

    self.dateToolbar = toolbar;

    self.historyDateSelect.inputView = self.datePicker;
    self.historyDateSelect.inputAccessoryView = self.dateToolbar;
}

And that's it. (I tested it locally and works)
