Question

I’m wondering how I might be able to implement a full screen inner shadow effect, similar to when the UIAlertView pops up. Is there an easy way to do this? Is there an api to bring up just the shadow portion of an alert in iOS? This is for iOS 4.0 and above by the way.

You could create a partially transparent image in Photoshop and add it as a subview. Something like this:

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"inner-shadow.png"]];
[self.view addSubview:imageView];
