Why am I still getting -[UIPopoverController dealloc] reached while popover is still visible

Question

Getting the following error:

-[UIPopoverController dealloc] reached while popover is still visible.

This is the code causing the problem:

-(void) showModalTime:(int)tag {

    UIViewController* popoverContent = [[UIViewController alloc] init];
    UIView *popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 216)];
    popoverView.backgroundColor = [UIColor redColor];
    popoverContent.contentSizeForViewInPopover = CGSizeMake(200.0, 216.0);

    //  smaller for timePicker
    timePicker=[[UIDatePicker alloc]init];
    timePicker.frame = CGRectMake(0, 0, 200, 216);

    timePicker.backgroundColor = UIColorFromRGB(0xeedd82);
    timePicker.datePickerMode = UIDatePickerModeTime;
    [timePicker setMinuteInterval:15];
    [timePicker addTarget:self action:@selector(dateDidChange:) forControlEvents:UIControlEventValueChanged];

    [popoverView addSubview:timePicker];
    popoverContent.view = popoverView;
    popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
    popoverController.delegate = (id)self;  //  <--  this is the line that's causing the crash
    [popoverController setPopoverContentSize:CGSizeMake(200, 216) animated:NO];

    switch (tag)  {  //  displays the popover datepicker
        case 11:  //  store open time
            [timePicker setTag:11];
            [popoverController presentPopoverFromRect:tfShopOpens.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
            break;
        case 12:  //  store close time
            [timePicker setTag:12];
            [popoverController presentPopoverFromRect:tfShopCloses.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
            break;
    }

}

PopoverController is defined as an instance variable:

@property (nonatomic, strong) UIPopoverController *popoverController;

I have marked the line causing the crash; I changed all of my PopoverControllers to instance variables and the problem appeared solved, but now has reared it's ugly head. What else can I do to prevent this?

Answer 1

check popoverController is visible or not in showModalTime method because popoverController overwrite

  if ([popoverController isPopoverVisible]) {
            [popoverController dismissPopoverAnimated:YES];
        }
