First a UIImage needs to be made, to make one with an image from the application bundle use this code:

UIImage *myImage = [ UIImage imageNamed: @"myImage.png" ];


If you need to make an image from a URL you can do something like this:
More info can be found about this technique here: http://idevkit.com/forums/tutorials-code-samples-sdk/3-one-line-uiimage-url.html

UIImage *myImage = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString: @"http://img.youtube.com/vi/OhOahwZCO1s/2.jpg"]]];


Now that the UIImage has been made it needs to be put into a UIImageView. This is simply done with the -initWithImage: method:

UIImageView *myImageView = [ [ UIImageView alloc ] initWithImage: myImage ];


You can then add the image view as a subview to any other view. You can also change the frame to resize the image.

    CVPixelBufferRef buffer = NULL;

    size_t width = [image size].width;
    size_t height = [image size].height;
    size_t bitsPerComponent = 8; // *not* CGImageGetBitsPerComponent(image);
    CGColorSpaceRef cs = CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB);

    size_t bytesPerRow = CVPixelBufferGetBytesPerRow(buffer);
    
    // context to draw in, set to pixel buffer's address
    CGContextRef ctxt = CGBitmapContextCreate(rasterData, width, height, bitsPerComponent, bytesPerRow, cs, bi);
    if(ctxt == NULL){
        NSLog(@"could not create context");
        return NULL;
    }
