代码实现:
    - (void)viewDidLoad 
{?       
 [super viewDidLoad];?    
    //给图层添加背景图片:?       
 //myView.layer.contents = (id)[UIImage imageNamed:@"view_BG.png"].CGImage;?        
//将图层的边框设置为圆脚?
myWebView.layer.cornerRadius = 8;? 
myWebView.layer.masksToBounds = YES;
//给图层添加一个有色边框?       
 myWebView.layer.borderWidth = 5;?        
myWebView.layer.borderColor = [[UIColor colorWithRed:0.52 green:0.09 blue:0.07 alpha:1] CGColor];?    
}
