title: UIDatePicker not updating UILabel
body: <p>I have a UIDatePicker and trying to update a UILabel in realtime based on the date selected by a user. If the user selects one date (say Jan 21st 2012) and then changes their mind to (say March 21st 2013) I want the UILabel to reflect the change.</p>
  
  <p>So far, the UILabel just reflects the current date and does not update it's text even after the user has selected another date from the UIDatePicker. I have also searched around pointers to fix this but to no avail. Any help will be appreciated. Thanks.</p>
  
  <p>Code so far:
  .h file, I have</p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet UILabel *entryDateSetLabel;
  @property (strong, nonatomic) IBOutlet UIDatePicker *entryDateSelected;
  
  - (IBAction)datePickerDateChanged:(id)sender;
  </code></pre>
  
  <p>the datePickerDateChanged is hooked up to the value changed event for the date picker</p>
  
  <p>the .m file,</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
  
      self.entryDateSelected = [[UIDatePicker alloc] init];
  
      [self.entryDateSelected addTarget:self action:@selector(datePickerDateChanged:) forControlEvents:UIControlEventValueChanged];
  }
  
  - (IBAction)datePickerDateChanged:(id)sender {
  
      NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init];
      [outputFormatter setDateFormat:@"MMMM d, yyyy"];
  
      NSString *entryDateInString = [outputFormatter stringFromDate:self.entryDateSelected.date];
  
      [[self entryDateSetLabel] setText: entryDateInString];
  }
  </code></pre>
