Answer 1

我想你已经为webview.That固定框架将不利于在实施定向CHAGE

尝试：

使用此代码为显示所述网页的view.Change堆栈上溢URL与您的URL;

contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
contentView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
self.view = contentView;
self.view.autoresizesSubviews = YES;


CGRect webFrame = [[UIScreen mainScreen] applicationFrame];
webFrame.origin.y -= 20.0;

webView = [[UIWebView alloc] initWithFrame:webFrame];

[contentView addSubview:webView]; 
webView.scalesPageToFit = YES;
webView.autoresizesSubviews = YES;
webView.autoresizingMask=(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth);
[webView setBackgroundColor:[UIColor clearColor]];
NSString *urlAddress = @"https://www.stackoverflow.com";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
webView.delegate =self;
[webView release];

要支持取向

   - (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) orientation 
{
return YES;

}

有关网络的视图与取向变化

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
if(fromInterfaceOrientation == UIInterfaceOrientationPortrait){
 [webView stringByEvaluatingJavaScriptFromString:@"rotate(0)"];

}
else{
    [webView stringByEvaluatingJavaScriptFromString:@"rotate(1)"];
}
}

希望上述将满足您的要求。 所有最好的。
