Shadow with corner radius in a cell with IBDesignables

Question

I have 2 subselects in a cell. One for the shadow view and the other for the corner radius, as it sounds pretty good what I found from this link . So I tried to do this in Objective-C using IBDessignables. Everything works fine if the cell is the same size, but for a shadow of dynamic size it is displayed above another cell, but the cornerview is fine.

- view cell hierarchy -

-- UITableViewCell
  -- contentView
     -- shadowView
       -- CornerView

Here is my code for shadow representation

ShadowView.h

IB_DESIGNABLE
@interface ShadowView : UIView
@property (nonatomic) IBInspectable CGFloat cornerRadius;
@property (nonatomic) IBInspectable CGFloat shadowRadius;
@property (nonatomic) IBInspectable CGSize  shadowOffset;
@end

ShadowView.m

@implementation ShadowView

-(void)setup{
    self.cornerRadius = 5.0f;
    self.shadowRadius = 2.0f;
    self.shadowOffset  = CGSizeMake(0, 0);
    self.backgroundColor = [UIColor clearColor];
}

- (instancetype)initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        [self setup];
    }
    return self;
}


- (id)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        [self setup];
    }
    return self;
}

- (void)drawRect:(CGRect)rect {
    [self updateLayerProperties];
}

- (void)updateLayerProperties {
    self.layer.shadowOffset = self.shadowOffset;
    self.layer.shadowRadius = self.shadowRadius;
    self.layer.shadowOpacity = 0.3;
    self.layer.shadowPath = [UIBezierPath bezierPathWithRoundedRect:self.bounds cornerRadius:self.cornerRadius].CGPath;
    self.layer.masksToBounds = NO;
    self.layer.shouldRasterize = YES;
    self.layer.rasterizationScale = [UIScreen mainScreen].scale;
}

@end

So does anyone know what the exact problem is? Because the angles of the angle of view work fine, but not the shadow representation.

Answer 1

, . , layoutSubviews ShadowView.

-(void)layoutSubviews {
    [super layoutSubviews];
    [self updateLayerProperties];
}
