在UIWebView中设置cookie

 本文转载至 http://blog.csdn.net/chengyakun11/article/details/8863878

 

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

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。

//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) {
