iOS:自动加载 UIWebView

Question

我有两个 View Controller 。在我的第一个 viewController 中，我准备了一个网址，只要我按下一个按钮，第二个 View Controller 就会在 Web View 中打开该地址。我不确定如何使用地址自动加载 webView。我的意思是，我不确定在第二个 View Controller 中调用 loadRequest 的位置。我无法在 viewDidLoad 中调用，因为届时不会发送地址。

WebViewController *webViewController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:nil];
webViewController.query = [self getQuery:[query text]];
UINavigationController *navController = [[UINavigationController alloc]
                                         initWithRootViewController:webViewController];

// [navController pushViewController:subView animated:YES];
[[navController navigationBar] setHidden:YES];
[navController setToolbarHidden:YES];
[navController setModalPresentationStyle:UIModalPresentationCurrentContext];
[self presentViewController:navController animated:YES completion:nil];

你可以在第二个 View Controller 的 viewWillAppear 中写这个

UIViewController *webViewController = [[UIViewController alloc]init];

UIWebView *webView = [[UIWebView alloc]initWithFrame:CGRectMake(0,0,320,480)];
webView.scalesPageToFit= YES;
NSString *url;
url =[NSString stringWithFormat:@"www.google.com"];
NSURL *nsurl = [NSURL URLWithString:url];

NSURLRequest *nsrequest = [NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];
[webViewController.view addSubview:webView];
[self.navigationController pushViewController:webViewController  animated:YES];
