Fix custom format bug in datePickerValueChagned method.

[Deleted user]

datePickerValueChanged bug:

//Doesn't check for self.dataFormat

//NOW:

• (void)datePickerValueChanged:(id)sender{
  UIDatePicker datePicker = (UIDatePicker)sender;

  NSDate *selectedDate = datePicker.date;

  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
  [
  dateFormatter setDateFormat:@"MM/dd/YY"];

  [_textField setText:[dateFormatter stringFromDate:selectedDate]];

  [self validate];
  }

WITH FIXED BUG:

• (void)datePickerValueChanged:(id)sender{
  UIDatePicker datePicker = (UIDatePicker)sender;

  NSDate *selectedDate = datePicker.date;

  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

  if (self.dateFormat) {
  [dateFormatter setDateFormat:self.dateFormat];
  } else {
  [dateFormatter setDateFormat:@"MM/dd/YY"];
  }

  [_textField setText:[dateFormatter stringFromDate:selectedDate]];

  [self validate];
  }
