Add this to your method: 将此添加到您的方法:
NSString *urlAddress = @"http://myurl.com";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[detailWebView loadRequest:requestObj];
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
NSURL *websiteUrl = [NSURL URLWithString:@"http://www.google.com"];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:websiteUrl];
[myWebView loadRequest:urlRequest];
