iPad layer shadow effect for UIView


I am trying to display a UIView similar to this image url

Click here to view uiview image

This is a UIView containing UIimageview and label. Is there a way to set layer effect similar to this?

Thanks in advance Joe.


Solution

  • #import <QuartzCore/QuartzCore.h>
    

    you can use

    imageView.layer.shadowRadius = 2.0;
    imageView.layer.shadowOpacity = 0.7;
    imageView.layer.shadowColor = [UIColor blackColor].CGColor;
    imageView.layer.shadowPath = [self createArcShadowPathForRect:imageView.frame].CGPath
    
    #define archeight 25
    
    -(UIBezierPath *)createArcShadowPathForRect:(CGRect)rect {
    
        CGFloat h_padding =  (self.imageView.frame.size.width - rect.size.width) /2;
        CGFloat v_padding =  (self.imageView.frame.size.height - rect.size.height) /2-10;
    
        CGPoint startPoint =        CGPointMake(0 + h_padding, rect.size.height + v_padding) ;
        CGPoint pointTwo =          CGPointMake(0 + h_padding, rect.size.height + archeight + v_padding) ;
        CGPoint controlCenterPoint =   CGPointMake(rect.size.width/2 + h_padding, rect.size.height + v_padding+ 10);
        CGPoint leftDownPoint =     CGPointMake(rect.size.width + h_padding, rect.size.height + archeight + v_padding) ;
        CGPoint leftUpPoint =       CGPointMake(rect.size.width + h_padding, rect.size.height + v_padding) ;
    
        UIBezierPath *path = nil;
        if(!path) {
            path = [[UIBezierPath bezierPath] retain];
            [path moveToPoint:startPoint];
            [path moveToPoint:pointTwo];        
            [path addQuadCurveToPoint:leftDownPoint controlPoint:controlCenterPoint];
            [path addLineToPoint:leftUpPoint];
            [path addLineToPoint:startPoint];
            [path closePath];
    
        }
        return path;
    }
