Hi,

I am changing the image in UIImageView based on accelerometer input. The images are stored in an array. The application runs fine for a while and then crashes.

warning: check_safe_call: could not restore current frame

1. I am not using "UIImage ImageNamed" method when populating the array.
2. The total size of all images is around 12 Mb. But individual images are very light (<100 kb) and i am using only one image at a time from the array.
3. Just in case there are any autoreleases, I have allocated a NSAutoreleasePool in view did load and am draining it in the didReceiveMemoryWarning method (which does get called 2, 3 times before the app crashes?).

Following is the code that creates images array:

    //create autorelease pool as we are creating many autoreleased objects
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

NSMutableArray *finalarr = [[NSMutableArray alloc] initWithCapacity:9];

NSLog(@"start loading");
for(int y = 0; y < 100; y+=10)
{
    NSMutableArray *arr = [[NSMutableArray alloc] initWithCapacity:10];
    for(int x = 0; x < 10; x++)
    {
        NSString *imageName = [[NSString alloc] initWithFormat:@"0%d",y + x];

        UIImage *img = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imageName ofType:@"png"]];
        [arr addObject:img];

        [imageName release];
        [img release];
    }
    [finalarr addObject:arr];
    [arr release];

}

NSLog(@"done loading");
// Override point for customization after app launch
viewController.imagesArray = finalarr;
[finalarr release];
//retain the array of images
[viewController.imagesArray retain];

//release the aurtorelease pool to free memory taken up by objects enqued for release
[pool release];

As the app runs smoothly for a while, which means array creation is definitely not the problem.

After this the following method is called from [accelerometer didAccelerate]

-(BOOL)setImageForX:(int)x andY:(int)y
{

[self.imageView setImage:(UIImage*)[(NSArray*)[self.imagesArray objectAtIndex:y] objectAtIndex:x]]; return TRUE; }

So the only code being executed is the "UIImageView setImage". But no objects are being created here.

Please let me know if the code seems to have any leaks or i am doing something wrong.

Thanks,
Swapnil
