UIPopoverController iOS 8 crash.

I am getting frequent crash log in my app and this only happens in iOS8. I've done some tests but it seems to work in a simulator.

The code to represent it is something like this.

- (void) selectDate:(UIButton *)button
{
    SelectStartEndDate *selectStartEndDate = [[SelectStartEndDate alloc] initWithNibName:@"SelectStartEndDate" bundle:[NSBundle mainBundle]];
    selectStartEndDate.delegate = self;
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:selectStartEndDate];

    selectDate = [[UIPopoverController alloc] initWithContentViewController:navController];

    selectDate.popoverContentSize = CGSizeMake(320, 208 + 44);              
    [selectDate presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
    selectDate.delegate = self;
}

      

        
        
        
      

    

Thank!
