UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:imageView.bounds];

imageView.layer.masksToBounds = NO;

imageView.layer.shadowColor = [UIColor blackColor].CGColor;

imageView.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);

imageView.layer.shadowOpacity = 0.5f;

imageView.layer.shadowPath = shadowPath.CGPath;

//添加显示

UIImage *image = [UIImageimageNamed:@"touxiang"];

UIImageView *imageView = [[UIImageViewalloc]initWithImage:image];

imageView.frame =CGRectMake(50,100, 200,200);

//添加边框

// CALayer * layer = [imageView layer];

// layer.borderColor = [[UIColor redColor] CGColor];

// layer.borderWidth = 5.0f;

// imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;

// imageView.layer.borderWidth = 5.0f;

//添加四个边阴影

// imageView.layer.shadowColor = [UIColor greenColor].CGColor;//阴影颜色

// imageView.layer.shadowOffset = CGSizeMake(0, 0);//偏移距离

// imageView.layer.shadowOpacity = 0.5;//不透明度

// imageView.layer.shadowRadius = 10.0;//半径

//添加两个边阴影

imageView.layer.shadowColor = [UIColorblueColor].CGColor;//阴影颜色

imageView.layer.shadowOffset =CGSizeMake(4,4);//偏移距离

imageView.layer.shadowOpacity =0.5;//不透明度

imageView.layer.shadowRadius =2.0;//半径

[self.viewaddSubview:imageView];
