title: UIDatePicker leaks
body: <p>I appear to have a leaky UIDatePicker.  I have noted memory leaks for setting the datePickerMode to show date and time.  But, I'm only trying to display date.  I'm fairly certain this is a framework leak because when I comment out several UIDatePicker property assignments, the leaks go away.  This code leaks 1 CGColor object, and 1 UIDeviceRGBColor object:</p>
  
  <pre><code>datePicker = [[UIDatePicker alloc] initWithFrame:[self detailViewRect]];
  
  
  datePicker.datePickerMode = UIDatePickerModeDate; //leaks CGColor when setting this
  datePicker.hidden = NO;
  datePicker.timeZone = [NSTimeZone systemTimeZone]; //leaks UIDeviceRGBColor
  datePicker.maximumDate = [NSDate date];//leaks UIDeviceRGBColor
  datePicker.autoresizingMask = UIViewAutoresizingFlexibleWidth;
  </code></pre>
  
  <p>By commenting the lines Instruments reported as offending, I get no leaks:</p>
  
  <pre><code>datePicker = [[UIDatePicker alloc] initWithFrame:[self detailViewRect]];
  
  //datePicker.datePickerMode = UIDatePickerModeDate; //leaks CGColor when setting this
  datePicker.hidden = NO;
  //datePicker.timeZone = [NSTimeZone systemTimeZone]; //leaks UIDeviceRGBColor
  //datePicker.maximumDate = [NSDate date];//leaks UIDeviceRGBColor
  datePicker.autoresizingMask = UIViewAutoresizingFlexibleWidth;
  </code></pre>
  
  <p>Without at least date mode set, the UIDatePicker is worthless.  Does anyone have a workaround?  </p>
