Hello,
I have tried to develop an iPad app and everything is almost ok. One crash appears now and then and I do not understand what the error report is tryingt o tell me. I have noticed that this crash appears when I have a modalview open and rotate the iPad and also when I close the modal view. It never appears in the simualtor, only on the device. My thought about this is:
- it could have something to do with the rotating?
- the modalview is released even if the parentviewcontroller is "talking" to it?

Does anyone know what these msg in the error report are meaning? I dont know where to start...

Are you doing custom animations? If so, triple check how you're setting them up and memory management. If you're not, look in your dealloc and other areas where your views cross reference each other.

It appears to be happening right before an animation is about to be active, so it could be referencing a deallocated object. What does the top of your crash report look like?

Thanks a lot for your answer! No I do not do any custom animation. The crash appeared when I was in a modalview and then rotated the iPad. It does not alwas happend when I rotate the device....

I have looked through my code in order to detect some overretains etc but did not find anything. Perhaps, because I am looking in the wrong place?
This is how I open up the modalview:

Code: 
- (void) openDetail:(id)sender{
	DetailMapViewController *modal = [[DetailMapViewController alloc] 
			initWithNibName:@"DetailMapViewController" 
			bundle:[NSBundle mainBundle]]; 
	modal.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
	modal.modalPresentationStyle = UIModalPresentationFormSheet;
	[self presentModalViewController:modal animated:YES];
	[modal release];
}

The DetailMapViewController.h
Code: 
#import <UIKit/UIKit.h>
#import "Annotations.h"

@interface DetailMapViewController : UIViewController <MKMapViewDelegate> {
	IBOutlet MKMapView *map;
	Annotations *annotation;
	CLLocation *userLoc;
}
@property(nonatomic,retain)IBOutlet MKMapView *map;
@property(nonatomic,retain)Annotations *annotation;
@property(nonatomic,retain)CLLocation *userLoc;
- (IBAction) dismissView:(id)sender;
@end

The DetailMapViewController.m:
Code: 
#import "DetailMapViewController.h"

@implementation DetailMapViewController
@synthesize map,annotation,userLoc;


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];

//some labels are defined here and a map
	
	UIButton *close_btn = [UIButton buttonWithType:UIButtonTypeCustom];
	[close_btn setFrame:CGRectMake(500, 10, 30,30)];
	[close_btn setImage:[UIImage imageNamed:@"btn_close.png"] forState:UIControlStateNormal];
	[close_btn addTarget:self action:@selector(dismissView:) forControlEvents:UIControlEventTouchDown];
	[self.view addSubview:close_btn];
}


- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)a{
	Annotations *ann = (Annotations*)a;
	MKAnnotationView *annView=[[[MKAnnotationView alloc] initWithAnnotation:ann reuseIdentifier:@"currentloc"]autorelease];
	annView.canShowCallout = YES;
	UIImage *theimage = [UIImage imageNamed:@"pin.png"];
	[annView setImage:theimage];
	annView.centerOffset = CGPointMake(5,-20);
	
	if(ann == (Annotations *)map.userLocation) {
		annView = nil;
	}
	return annView;
}

- (IBAction) dismissView:(id)sender {
	[self.parentViewController dismissModalViewControllerAnimated:YES];
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
	return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown || interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}


- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];
    // Release any cached data, images, etc that aren't in use.
}


- (void)viewDidUnload {
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


- (void)dealloc {
	[annotation release];
	[map release];
	[userLoc release];
    [super dealloc];
}

Thanks in advance!

Hello again,
I do not know if this is is relevant for the former crash, but I have got another one and it is a bit more concreate. I thought that I have a leak (a huge one :-( ) making my popover to crash. In this popover i have a tabelview and that seem to be the problem. Perhaps is the former crash when the tabel scrolls...a scrolling is a kind of animation, right?

Ok here is the new crash report:

Maybe post your myTableViewCell class, seems like the crash is coming from its dealloc. I'm surprised you're getting memory warnings. May want to look into your memory usage and run Leaks.

Where does that Hamster come from?

Ha, I got my avatar years ago from an image search, but that's not my page. I don't know where the original came from. Maybe it's time to change it.. ;)

I have modified my tableViewCell class now and also the way I use this class from my tableViewDelegate. This is how I do it - what do you think about this solution? Till now it seems to work....

myTableViewCell.h
Code: 
#import <UIKit/UIKit.h>

@interface myTableViewCell : UITableViewCell {
	IBOutlet UILabel *primaryLabel;
	IBOutlet UILabel *secondaryLabel;
	IBOutlet UILabel *distanceLabel;
	IBOutlet UIImageView *cellImg;
}

@property(nonatomic,retain)IBOutlet UILabel *primaryLabel;
@property(nonatomic,retain)IBOutlet UILabel *secondaryLabel;
@property(nonatomic,retain)IBOutlet UILabel *distanceLabel;
@property(nonatomic,retain)IBOutlet UIImageView *cellImg;
@end


myTableViewCell.m
Code: 
#import "myTableViewCell.h"

@implementation myTableViewCell
@synthesize primaryLabel,secondaryLabel,distanceLabel,cellImg;
- (id)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier {
    if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) {
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];
}

- (void)dealloc {
	[cellImg release];
	[primaryLabel release];
	[secondaryLabel release];
	[distanceLabel release];
    [super dealloc];
}
@end


in the popOverClass aka the tableViewDelegate, displaying the table
Code: 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	NSLog(@"cellForRowAtIndexPath");
	static NSString *CellIdentifier = @"CustomCell";
	
    myTableViewCell *cell = (myTableViewCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
		NSLog(@"cell == nil");
		NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"myTableViewCell" owner:self options:nil];
		for (id currentObject in topLevelObjects){
			NSLog(@"id currentObject in topLevelObjects");
			if ([currentObject isKindOfClass:[UITableViewCell class]]){
				NSLog(@"[currentObject isKindOfClass:[UITableViewCell class]]");
				cell =  (myTableViewCell *) currentObject;
				break;
			}
		}
	}
	UIView* backgroundView = [[UIView alloc] initWithFrame:CGRectZero];
	
	if(indexPath.row % 2 == 0){
		backgroundView.backgroundColor = LIGHT_BACKGROUND;
	}
	else {
		backgroundView.backgroundColor = [UIColor whiteColor];
	}
	cell.backgroundView = backgroundView;
	[backgroundView release];

	Annotations *annotationForCell =  [item_list objectAtIndex:[indexPath row]];
	cell.cellImg.image = [UIImage imageNamed:[annotationForCell tableCellImg]];
	cell.primaryLabel.text = [annotationForCell title];
	cell.secondaryLabel.text = [annotationForCell subtitle];
	cell.distanceLabel.text = [NSString stringWithFormat:@"%.2f km",([annotationForCell distance]/1000)];
	
	return cell;
}

Thanks in advance!
