Question

我来到了能够锁定水平滚动的地方，但是当我从横向旋转到肖像时，内容仍然很大。我需要自己调整大小/缩小它，但我不知道到目前为止如何使用它：

- (void)viewDidLoad

{
    [super viewDidLoad];
    NSString *fullURL = @"http://igo.nl";
    NSURL *url = [NSURL URLWithString:fullURL];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [_webView loadRequest:requestObj];
    _webView.scrollView.bounces = false;
    _webView.scalesPageToFit = YES;
    _webView.contentMode = UIViewContentModeScaleAspectFit;
}


    - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
    {

        if(fromInterfaceOrientation == UIInterfaceOrientationPortrait)
        {
            //_webView.scrollView.contentSize = CGSizeMake(320, _webView.scrollView.contentSize.height);
        }
        else
        {
            //[_webView reload];
            _webView.bounds = CGRectMake(0, 0, 320,_webView.bounds.size.height);
            _webView.frame = CGRectMake(0, 0, 320, _webView.frame.size.height);
            _webView.scrollView.contentSize = CGSizeMake(320, _webView.scrollView.contentSize.height);

        }
    }

编辑：我似乎需要的是内容缩小

Answer 1

使用UIWebViewDelegate

的委托方法

@interface YOUR_CLASS : PARENT_CLASS <UIWebViewDelegate>

在viewDidLoad

...
[_webView setDelegate:self];
...

调用委托方法

- (void)webViewDidFinishLoad:(UIWebView *)webView {

    [webView.scrollView setContentSize: CGSizeMake(webView.frame.size.width, webView.scrollView.contentSize.height)];

}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [_webView reload];    //Or use meta tag

    [_webView.scrollView setContentSize: CGSizeMake([_webView.scrollView.contentSize.width, _webView.scrollView.contentSize.height)];
}

您必须将meta标记添加到HTML文件

<meta name="viewport" content="width=device-width" />

或只是重新加载webView

[_webView reload];

Answer 2

尝试

-(void)viewWillLayoutSubviews
{
------
}

使用

计算

self.view.bounds.size.width,
self.view.bounds.size.height

Answer 3

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{

if(toInterfaceOrientation==UIInterfaceOrientationPortrait && toInterfaceOrientation!=UIInterfaceOrientationPortraitUpsideDown )
   {


   }
 else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation ==UIInterfaceOrientationLandscapeRight)
   {

   }
}

UIWebView内容如何调整大小/扩展呢？
