//本地拿到存储的cookies

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"cookiesInfo" ofType:@"plist"];
    NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
    NSArray *cookies = [data objectForKey:@"cookiesKey"];
    NSURL *url = [NSURL URLWithString:HomeBseUrl];
    if (cookies) {
        if (isClearCookies) {
            //清除cookies
            NSHTTPCookie *cookie;
            NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
            for (cookie in [storage cookies])
            {
                [storage deleteCookie:cookie];
            }
            //缓存web清除
            [[NSURLCache sharedURLCache] removeAllCachedResponses];
            NSURLCache * cache = [NSURLCache sharedURLCache];
            [cache removeAllCachedResponses];
            [cache setDiskCapacity:0];
            [cache setMemoryCapacity:0];
            if (url) {
       //清除所有cookie
                NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:url];
                for (int i = 0; i < [cookies count]; i++) {
                    NSHTTPCookie *cookie = (NSHTTPCookie *)[cookies objectAtIndex:i];
                    [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
                }
            }
        }else{
           //设置cookies 
            NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
            [cookieProperties setObject:[cookies objectAtIndex:0] forKey:NSHTTPCookieName];
            [cookieProperties setObject:[cookies objectAtIndex:1] forKey:NSHTTPCookieValue];
            [cookieProperties setObject:[cookies objectAtIndex:3] forKey:NSHTTPCookieDomain];
            [cookieProperties setObject:[cookies objectAtIndex:4] forKey:NSHTTPCookiePath];
            NSHTTPCookie *cookieuser = [NSHTTPCookie cookieWithProperties:cookieProperties];
            [[NSHTTPCookieStorage sharedHTTPCookieStorage]  setCookie:cookieuser]; 
        } 
    }

//设置完后再加载webView loadingrequest

//获取cookies 并持久化

NSHTTPCookie *cookie;
    NSHTTPCookieStorage *nCookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray *cookiesURL = [nCookies cookiesForURL:[NSURL URLWithString:HomeBseUrl]];
    for (id c in cookiesURL)
    {
        if ([c isKindOfClass:[NSHTTPCookie class]])
        {
            cookie=(NSHTTPCookie *)c;
            if ([cookie.name isEqualToString:@"PHPSESSID"]) {
                NSNumber *sessionOnly = [NSNumber numberWithBool:cookie.sessionOnly];
                NSNumber *isSecure = [NSNumber numberWithBool:cookie.isSecure];
                NSArray *cookies = [NSArray arrayWithObjects:cookie.name, cookie.value, sessionOnly,          cookie.domain, cookie.path, isSecure, nil];
                NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"cookiesInfo" ofType:@"plist"];
                NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
                [data setObject:cookies forKey:@"cookiesKey"];
                NSLog(@"________%@", data);//直接打印数据。
                [data writeToFile:plistPath atomically:YES]; 
                break;
            }
        }
    }

//如果存取不成功，可以新建一个名为cookiesInfo的plist文件

用的话自己调整一下存cookies 的地方 我目前在viewWilldisappear 和 应用程序退出时存的
