Question

I have a UIImageView in my application. I want to make it so that when you click on the UIImageView, the photo appears full screen as it does when you click on a photo in the Photos app.
What I want to know is if Apple released an API for doing this – I’ve seen apps like the wired app do it, where you click on a photo and it goes full screen – what’s this called? So I can research it.

Thanks,

Sam

What I would do is create a new UIViewController that had a UIImageView that took up the whole view. I would expose a public property that would allow me to set the image of the UIImageView.

Then have your UIImageView respond to a UIControlEventTouchUpInside event like so: [imageView addTarget:self action:@selector(imagePressed:) forControlEvents:UIControlEventTouchUpInside];

Then in imagePressed: set the UIViewController‘s image property, then push the new UIViewController onto navigation controller.
