How do I draw a shadow under a UIView?
A by far easier approach is to set some layer attributes of the view on initialization:
self.layer.masksToBounds = NO;self.layer.shadowOffset = CGSizeMake(-15, 20);self.layer.shadowRadius = 5;self.layer.shadowOpacity = 0.5;You need to import QuartzCore.
#import <QuartzCore/QuartzCore.h>
self.layer.masksToBounds = NO;self.layer.cornerRadius = 8; // if you like rounded cornersself.layer.shadowOffset = CGSizeMake(-15, 20);self.layer.shadowRadius = 5;self.layer.shadowOpacity = 0.5;This will slow down the application. Adding the following line can improve performance as long as your view is visibly rectangular:
self.layer.shadowPath = [UIBezierPath bezierPathWithRect:self.bounds].CGPath;
Same solution, but just to remind you: You can define the shadow directly in the storyboard.
