    copied!<p>I spent my whole 2weeks for just trying to resolve this problem. So frustrate!</p> <p>Following 2 functions are what I'm using for fetching a image from device library. If I use "setImage" function multiple times I keep losing my free memory on my iOS Device.</p> <p>I think "<strong>[imageFromAsset initWithCGImage:[[myasset defaultRepresentation] fullScreenImage]];</strong>" in assetImage function causes the problem. </p> <p>Can any guys help me? Any clues or thinking would be SUPER appreciate! Please!</p> <pre><code>- (void)setImage:(NSURL *)imageURL{ UIImage *imageFromDeviceLibrary = [[UIImage alloc] init]; [[DevicePhotoControl sharedInstance] assetImage:[imageURL absoluteString] imageToStore:imageFromDeviceLibrary]; UIImageView *fullImageView = [[UIImageView alloc] initWithImage:imageFromDeviceLibrary]; [imageFromDeviceLibrary release]; [self.view addSubview:fullImageView]; [fullImageView release]; } - (void)assetImage:(NSString *)assetURL imageToStore:(UIImage *)imageFromAsset{ // Handling exception case for when it doesn't have assets-library if ([assetURL hasPrefix:@"assets-library:"] == NO) { assetURL = [NSString stringWithFormat:@"%@%@",@"assets-library:",assetURL]; } __block BOOL busy = YES; ALAssetsLibrary* assetslibrary = [[[ALAssetsLibrary alloc] init] autorelease]; //get image data by URL ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset) { [imageFromAsset initWithCGImage:[[myasset defaultRepresentation] fullScreenImage]]; busy = NO; }; ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror) { NSLog(@"Library Image Fetching Failed : %@",[myerror localizedDescription]); busy = NO; }; [assetslibrary assetForURL:[NSURL URLWithString:assetURL] resultBlock:resultblock failureBlock:failureblock]; while (busy == YES) { [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; } } </code></pre>
