UIImage Reflection Tutorial

- (void) loadView {
	[super loadView];
	self.view.backgroundColor = [UIColor blackColor];

	// Modify the image name accordingly
	UIImage *image = [UIImage imageNamed:@\"spongebob.png\"];
	
	UIImageView *imageView = [[UIImageView alloc]initWithImage:image];

	CGImageRef imageToSplit = image.CGImage;
        // I'm using the lower 1/3 of the image only
	CGImageRef partOfImageAsCG = CGImageCreateWithImageInRect(imageToSplit, CGRectMake(0,(image.size.height*2)/3,image.size.width, image.size.height/3));
        // Create an UIImage instance of the image part
	UIImage *partOfImage = [UIImage imageWithCGImage:partOfImageAsCG];
	// Flip the UIImage mirrored upside-down
        UIImage* flippedImage = [UIImage imageWithCGImage:partOfImage.CGImage scale:1.0 orientation:  UIImageOrientationDownMirrored];
	
	UIImageView *reflectionView = [[UIImageView alloc]initWithImage:flippedImage];
	reflectionView.frame = CGRectMake(0, image.size.height, image.size.width, image.size.height/2);

        // Initialize ImageContext with the combined sizes of the imageView (original image) and the reflectionView
	UIGraphicsBeginImageContext(CGSizeMake(imageView.image.size.width,imageView.image.size.height+reflectionView.image.size.height));  
	// Creates an CGRect with the imageView content
	CGRect imageRect = CGRectMake(0, 0, imageView.image.size.width, imageView.image.size.height);
        // Creates an CGRect with the reflectionView content
	CGRect reflectionRect = CGRectMake(0, imageView.image.size.height, reflectionView.image.size.width, reflectionView.image.size.height);
	//shows the imageView at full size 
	[imageView.image drawInRect:imageRect]; 
	//displays the reflection with 0.5 transparent
        [reflectionView.image drawInRect:reflectionRect blendMode:kCGBlendModeScreen alpha:0.5];  
	
        // Creates an UIImage instance of the resulting image context
	UIImage *resultingImage = UIGraphicsGetImageFromCurrentImageContext();  
	UIGraphicsEndImageContext();

	// Creates the resulting view
	UIImageView *resultingView = [[UIImageView alloc]initWithImage:resultingImage];

        // Displays the image view on screen
	[self.view addSubview:resultingView];
