UIDatePicker memory leak in IOS 8.3 - ios

Question

I am seeing memory leaks in UIDatePicker when used in a popover on an iPad running IOS 8.3. I'm getting approx 5K in multiple memory leaks every time the date picker is popped up and then dismissed. The leaked object is NSDateComponents, and the responsible frame is [_UIDatePickerMode _yearlessYearForMonth:].
I have written a simple test app to demonstrate the problem (https://github.com/david-ape/datepickertest/). I've included both a UIPopoverController option and a UIPopoverPresentationController option, but it doesn't seem to matter which is used.
Am I doing something wrong, or is there a workaround, or do I need to wait for a fix from Apple? If the latter, then can anyone suggest a third party control that I could use in place of UIDatePicker?
Below is the code I'm using to pop up the date pickers.

#interface ViewController : UIViewController <UIPopoverControllerDelegate,
UIPopoverPresentationControllerDelegate>

#import "ViewController.h"
#interface ViewController ()
#property (nonatomic, strong) UIPopoverController *ios7Popover;

- (IBAction)datePickerPopupIOS8:(UIButton *)sender;
#end
#implementation ViewController
// helper - returns a view controller containing a date picker for use in a
// popup
+ (UIViewController *)buildDatePickerViewController
{
CGRect frame = CGRectMake(0, 0, 350, 216);
UIViewController *viewController = [[UIViewController alloc]init];
viewController.preferredContentSize = frame.size;
UIDatePicker *datepicker = [[UIDatePicker alloc]initWithFrame:frame];
datepicker.datePickerMode = UIDatePickerModeDate;
datepicker.hidden = NO;
datepicker.date = [NSDate date];
[viewController.view addSubview:datepicker];
return viewController;
}
// popup date picker using UIPopoverController (IOS7 compatible)
- (IBAction)datePickerPopupIOS7:(UIButton *)sender
{
UIViewController *viewController = [ViewController buildDatePickerViewController];
self.ios7Popover = [[UIPopoverController alloc]initWithContentViewController:viewController];
self.ios7Popover.delegate = self;
[self.ios7Popover presentPopoverFromRect:sender.frame
inView:self.view
permittedArrowDirections:(UIPopoverArrowDirectionUp|UIPopoverArrowDirectionDown| UIPopoverArrowDirectionLeft|UIPopoverArrowDirectionRight)
animated:YES];
}
// popup date picker using UIPopoverPresentationController (IOS8 or later required)
// Thanks to http://stackoverflow.com/a/26944036/1764243 for how to do this

popover.delegate = self;

popover.sourceRect = [sender frame];
destNav.navigationBarHidden = YES;
