You need to modify the view's CALayer property:

(v can be your UIImageView)

[v.layer setCornerRadius:30.0f];
[v.layer setBorderColor:[UIColor lightGrayColor].CGColor];
[v.layer setBorderWidth:1.5f];
[v.layer setShadowColor:[UIColor blackColor].CGColor];
[v.layer setShadowOpacity:0.8];
[v.layer setShadowRadius:3.0];
[v.layer setShadowOffset:CGSizeMake(1.0, 5.0)];

You can change all of these properties to match your needs or color scheme.

Also, take a look at the CALayer Class Reference.
