我尝试创建一个嵌入了webview的故事板 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"]]];

答案 0 :(得分:2)
将代码放在 viewDidAppear方法中,而不是 viewDidLoad 方法
- (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]; }
