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
I am not using "UIImage ImageNamed" method when populating the array.
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.
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
