    imageView.layer.shadowColor = [UIColor blackColor].CGColor;
imageView.layer.shadowOffset = CGSizeMake(0, 1);
imageView.layer.shadowOpacity = 1;
imageView.layer.shadowRadius = 1.0;

    Don’t forget to #import <QuartzCore/QuartzCore.h> in your implementation.

    EDIT:

    Adding in @Luke’s comment:

    Just a little gotcha that might save some other people some time make sure you have not set layer.masksToBounds to YES on your view otherwise the shadow will not appear.
