IOS: How to make a shadow for UIView on 4 side (top,right,bottom and left)

Question

I am using the code below to make the shadow for my ImageView

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:self.avatarImageView.bounds]; self.avatarImageView.layer.masksToBounds = NO; self.avatarImageView.layer.shadowColor = [UIColor blackColor].CGColor; self.avatarImageView.layer.shadowOffset = CGSizeMake(5.0f, 5.0f); self.avatarImageView.layer.shadowOpacity = 0.8f; self.avatarImageView.layer.shadowPath = shadowPath.CGPath; 

It will drop a shadow in the right and bottom like this image.

Now I want to make my ImageView also have a shadow in top and left. What should I change in code? Is possible to make the view contains shadow in top,right,bottom,left by config in code only or I need to create other layout view for shadow? Any help would be great appreciated.

Here is what I want to achieve

Update
Thank @Dipen Panchasara for give a simple solution. Follow @Dipen Panchasara (with the shadow color is black) I will have the shadow image like this

Only following code will do the job for your requirement, You don't need to create UIBezierPath for shadow path.

// *** Set masks bounds to NO to display shadow visible *** self.avatarImageView.layer.masksToBounds = NO; // *** Set light gray color as shown in sample *** self.avatarImageView.layer.shadowColor = [UIColor lightGrayColor].CGColor; // *** *** Use following to add Shadow top, left *** self.avatarImageView.layer.shadowOffset = CGSizeMake(-5.0f, -5.0f);  // *** Use following to add Shadow bottom, right *** //self.avatarImageView.layer.shadowOffset = CGSizeMake(5.0f, 5.0f);  // *** Use following to add Shadow top, left, bottom, right *** // avatarImageView.layer.shadowOffset = CGSizeZero; // avatarImageView.layer.shadowRadius = 5.0f;  // *** Set shadowOpacity to full (1) *** self.avatarImageView.layer.shadowOpacity = 1.0f;

Like this:

float shadowSize = 10.0f; UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:CGRectMake(self.avatarImageView.frame.origin.x - shadowSize / 2,                                                                        self.avatarImageView.frame.origin.y - shadowSize / 2,                                                                        self.avatarImageView.frame.size.width + shadowSize,                                                                        self.avatarImageView.frame.size.height + shadowSize)]; self.avatarImageView.layer.masksToBounds = NO; self.avatarImageView.layer.shadowColor = [UIColor blackColor].CGColor; self.avatarImageView.layer.shadowOffset = CGSizeMake(0.0f, 0.0f); self.avatarImageView.layer.shadowOpacity = 0.8f; self.avatarImageView.layer.shadowPath = shadowPath.CGPath; 

Swift 3 version:

    let shadowSize : CGFloat = 5.0     let shadowPath = UIBezierPath(rect: CGRect(x: -shadowSize / 2,                                                y: -shadowSize / 2,                                                width: self.avatarImageView.frame.size.width + shadowSize,                                                height: self.avatarImageView.frame.size.height + shadowSize))     self.avatarImageView.layer.masksToBounds = false     self.avatarImageView.layer.shadowColor = UIColor.black.cgColor     self.avatarImageView.layer.shadowOffset = CGSize(width: 0.0, height: 0.0)     self.avatarImageView.layer.shadowOpacity = 0.5     self.avatarImageView.layer.shadowPath = shadowPath.cgPath
