- (void)viewDidLoad

{

[super viewDidLoad];

UIImage *image = [UIImage imageNamed:@"0_wanggsx20080817.jpg"];

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

imageView.frame = CGRectMake(50, 100, 200, 300);

//添加 边框

CALayer * layer = [imageView layer];

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

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 = [UIColor blueColor].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.view addSubview:imageView];
