iOS UIWebView无法缩放内容

Question

我的UIWebView总是小于设备的屏幕。无论我尝试什么，它都只是不会扩大网站规模以适应它的范围。

这是我的代码：

    self.webView = [[UIWebView alloc] initWithFrame:
                    CGRectMake(.08 * width, .18 * height, .84 * width, .74 * height)];
    self.webView.delegate = self;
    self.webView.scrollView.delegate = self;
    self.webView.scrollView.scrollEnabled = NO;
    self.webView.scalesPageToFit = YES;
    NSString *urlAddress = @"https://number26.de/app-tutorial/dist/new-feature-invite.html";
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [self.webView loadRequest:requestObj];
    [self.view.window addSubview:self.webView];

结果如下：

这就是它应该是什么样子（Google Chrome / Dev模式）：

okey，这是我的代码

- (void)viewDidLoad {
       [super viewDidLoad];



       self.webView = [[UIWebView alloc] init];
       self.webView.frame = CGRectMake(.08 * self.view.frame.size.width, .18 *         self.view.frame.size.height, .84 * self.view.frame.size.width, .74 * self.view.frame.size.height);

      self.webView.delegate = self;
      self.webView.scrollView.delegate = self;
      self.webView.scrollView.scrollEnabled = NO;
      NSString *urlAddress = @"https://s.number26.de/app-tutorial/dist/new-feature-invite.html";
      NSURL *url = [NSURL URLWithString:urlAddress];
      NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

      [self.webView loadRequest:requestObj];
      [self.view addSubview:self.webView];


      self.webView.scalesPageToFit = YES;

}


 -(void)webViewDidFinishLoad:(UIWebView *)webView {
     [self scaleToFit];
 }

-(void)scaleToFit
{
    if ([self.webView respondsToSelector:@selector(scrollView)])
    {
         UIScrollView *scroll=[self.webView  scrollView];

         float zoom=self.webView .bounds.size.width/scroll.contentSize.width;
         [scroll setZoomScale:zoom animated:YES];
    }
}

并在webView中查看完整网站。 ]

添加此代码

-(void)webViewDidFinishLoad:(UIWebView *)webView {
       [self scaleToFit];
}

-(void)scaleToFit
{
       if ([self.webView respondsToSelector:@selector(scrollView)])
       {
              UIScrollView *scroll=[self.webView  scrollView];

              float zoom=self.webView .bounds.size.width/scroll.contentSize.width;
              [scroll setZoomScale:zoom animated:YES];
       }
}
