How can I make UIImageView change its image programmatically?

Question

I have this code:

- (void)viewDidLoad {
[super viewDidLoad];
landscape.image = [UIImage imageNamed:@"tenerife1.png"];
}

First, I created an UIImageView with IBOutlet. Landscape is pointing to that UIImageView. In InterfaceBuilder I told to show an specific image in that UIImageView. It never changes. I always see the image I specified in InterfaceBuilder. But I want to set it programmatically. How can I do this?

Try calling setNeedsDisplay on the view after you change the image:

   [landscape setNeedsDisplay];
