@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.webView = [[UIWebView alloc] initWithFrame:[UIScreen mainScreen].bounds];
    [self.view addSubview:self.webView];
    self.webView.delegate = self;
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://m.ys137.com/article_803088.html"]];
    [self.webView loadRequest:request];
    //自适应屏幕大小
    self.webView.scalesPageToFit = YES;
}

//UIWebView的代理方法
