Question

I try using my app ALAssetRepresentation.and when i loop om an images there are couple of image that crash the app

for(ALAsset *asset in _assets) {
        NSMutableDictionary *workingDictionary = [[NSMutableDictionary alloc] init];
        [workingDictionary setObject:[asset valueForProperty:ALAssetPropertyType] forKey:@"UIImagePickerControllerMediaType"];

        ALAssetRepresentation *representation = [asset defaultRepresentation];

        if (!representation) {
            [workingDictionary release];
            continue;
        }
        CGImageRef imageRef = [representation fullResolutionImage];//here the app crash
            UIImage *img = [UIImage imageWithCGImage:imageRef];
    if (!img) {
        [workingDictionary release];
        continue;
    }
    if (!img) {
        [workingDictionary release];
        continue;
    }

    [workingDictionary setObject:img forKey:@"UIImagePickerControllerOriginalImage"];
    [workingDictionary setObject:[asset valueForProperty:ALAssetPropertyOrientation] forKey:@"orientation"];

    [returnArray addObject:workingDictionary];
    [workingDictionary release];    
}

in this line i get crash without any msg:

CGImageRef imageRef = [representation fullResolutionImage];

This is the crash msg

    Program received signal:  “0”.
Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib")

Answer 1

That is most likely due to running out of memory, how big are the images that cause the crash?
