Now modify the ViewDidLoad method in ViewController.m

- (void)viewDidLoad
{
  [super viewDidLoad];
  //1
  NSString *urlString = @"http://ioscreator.com";
  //2
  NSURL *url = [NSURL URLWithString:urlString];
  //3
  NSURLRequest *request = [NSURLRequest requestWithURL:url];
  //4
  NSOperationQueue *queue = [[NSOperationQueue alloc] init];
  //5
  [NSURLConnection sendAsynchronousRequest:request queue:queue
    completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    if ([data length] > 0 && error == nil) [myWebView loadRequest:request];
     else if (error != nil) NSLog(@"Error: %@", error);
  }];
}

在UIWebView中设置cookie

项目中，需要在打开3g网页时，通过cookie传递一些信息。

实现代码如下：

在

[plain] view plaincopy
NSURL *url = [NSURL URLWithString:_urlstr];
//NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:60];
[self.myWeb loadRequest:request];
之前，设置或者删除cookie。

[plain] view plaincopy
//////////////////////////////////////////////////////
//设置cookie

• (void)setCookie{

  NSMutableDictionary *cookiePropertiesUser = [NSMutableDictionary dictionary];
  [cookiePropertiesUser setObject:@"cookie_user" forKey:NSHTTPCookieName];
  [cookiePropertiesUser setObject:uid forKey:NSHTTPCookieValue];
  [cookiePropertiesUser setObject:@"xxx.xxx.com" forKey:NSHTTPCookieDomain];
  [cookiePropertiesUser setObject:@"/" forKey:NSHTTPCookiePath];
  [cookiePropertiesUser setObject:@"0" forKey:NSHTTPCookieVersion];

  // set expiration to one month from now or any NSDate of your choosing
  // this makes the cookie sessionless and it will persist across web sessions and app launches
  /// if you want the cookie to be destroyed when your app exits, don't set this
  [cookiePropertiesUser setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

  NSHTTPCookie *cookieuser = [NSHTTPCookie cookieWithProperties:cookiePropertiesUser];
  [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookieuser];
  }

//清除cookie

• (void)deleteCookie{
  NSHTTPCookie *cookie;

  NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];

  NSArray *cookieAry = [cookieJar cookiesForURL: [NSURL URLWithString: _urlstr]];

  for (cookie in cookieAry) {

  [cookieJar deleteCookie: cookie];  
  

  }
  }
