iphone - 使用http请求xcode请求谷歌主页 - 目标C

Question

以下是我用于 http 请求的代码行。在运行模拟器时，我只得到“显示的连接”.. 有人可以帮助我使用正确的代码以显示谷歌主页。谢谢。

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http:www.google.com"] cachePolicy: NSURLRequestUseProtocolCachePolicy timeoutInterval: 15.0];

    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest: request delegate:self];

    if(connection){
        //connect
        label.text = @"connecting .....";

    }else{
        //error

    }
}


-(void) connection: (NSURLConnection *)conenction didReceiveData:(NSData *)data{

    response =  [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

}


-(void) connectionDidFinishLoading:(NSURLConnection *)connection{
    connection = nil;
}

试试这个

NSURL *url = [NSURL URLWithString:@"http://www.google.com"];

if (![[UIApplication sharedApplication] openURL:url])
   NSLog(@"%@%@",@"Failed to open url:",[url description]);
