iphone - Webview 在 iPhone 中自动调整为纵向和横向 View

Question

我是 iPhone 开发新手。在我的应用程序中，我想以 C 纵向方向在设备中显示 Web View 。它还应该支持横向方向。我使用了以下方法，但没有预期的输出。

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{

return (interfaceOrientation == UIInterfaceOrientationPortrait || 

 interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == 

UIInterfaceOrientationLandscapeRight);
}

请指导我。请帮助我。谢谢

我认为您已经为 webview 设置了固定框架。这在实现方向变化时没有帮助

试试这个:

使用此代码显示 Web View 。将堆栈溢出 URL 更改为您的 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];

支持方向

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

}

对于随方向变化的 WebView

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

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

希望以上内容能够满足您的需求。祝一切顺利。
