Question

Can anyone describe a way to create an animated scaling affect on the iPhone? I would like an image to start small, and then grow while fading. Motion tweening would also be helpful. Is quartz neccessary for this? I’d prefer to use something as simple as possible.

Thanks SO!

You can use

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];

myImageView.alpha = 0.0;
myImageView.size = CGSizeMake(myImageView.size.width*2,myImageView.size.height*2);

[UIView commitAnimations];

This does require the CoreAnimations framework to be added to your project.
