如何在 IOS 自定义键盘应用程序扩展的 InputView 中嵌入 WebView

Question

我尝试创建一个嵌入了 webview 的故事板然后在 ViewController 控制器 class 中，在 viewDidLoad 方法中 :

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

将代码放在 viewDidAppear 方法 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];

}
