我尝试创建一个故事板，其中嵌入了 webview 然后在 ViewController 控制器类中，在 viewDidLoad 方法中：

[self.myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.google.com"]]];

【问题讨论】：

我在尝试将联系人视图控制器嵌入自定义键盘时遇到了类似的问题。您的模拟器/测试设备是什么 iOS 版本？
我在 ios 10 上测试它
您找到解决方案了吗？
运气好吗@ShubhamJha ？也有这个问题
尝试以下解决方案

【解决方案1】：

将代码放在 viewDidAppear 方法 中，而不是 viewDidLoad 方法中

- (void)viewDidAppear:(BOOL)animated { CGRect screenRect = [[UIScreen mainScreen] bounds]; CGFloat screenWidth = screenRect.size.width; //CGFloat screenHeight = screenRect.size.height; UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, screenWidth, 800)]; NSString *urlString = @"http://mum00blf.in.oracle.com:7777/index/public/login.html"; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url]; [webView loadRequest:urlRequest]; /*dispatch_async(dispatch_get_main_queue(), ^(void){ [self.view addSubview:webView]; });*/ [self.view addSubview:webView]; }
