Difference between UIImage and UIImageView

Question

What is the difference between UIImage and UIImageView? Can someone explain it with an example?

Answer 1

In short: You create an instance of UIImage object to hold image's data, like this:

 NSString *sourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"/picture.jpg"]; //assuming your image is in your app's bundle
UIImage *img = [[UIImage alloc]initWithContentsOfFile:sourcePath];

You then create an instance of UIImageView either through IB or code to display your image on the screen, like this:

[imageView1 setImage:img];  //assume you already create an instance of UIImageView named imageView1
