這一個UIView ipad公司層陰影效果是含有的UIImageView和標籤一個UIView。 有沒有設置圖層效果的方法？

#import <QuartzCore/QuartzCore.h> 

可以使用

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; 
}
