iOS UIWebView和WKWebView 设置,获取,清除cookie
1.设置cookie

    NSURLRequest *request =[NSURLRequest requestWithURL:url];
    NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
    [cookieProperties setObject:@"key" forKey:NSHTTPCookieName];
    [cookieProperties setObject:@"value" forKey:NSHTTPCookieValue];
    [cookieProperties setObject:@"dev.skyfox.org" forKey:NSHTTPCookieDomain];
    [cookieProperties setObject:@"dev.skyfox.org" forKey:NSHTTPCookieOriginURL];
    [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
    [cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];
    设置失效时间
    [cookieProperties setObject:[NSDate dateWithTimeIntervalSinceNow:5] forKey:NSHTTPCookieExpires];
   设置sessionOnly
    [cookieProperties setObject:@"0" forKey:NSHTTPCookieDiscard]; 
    NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
     加载网页
    [webView loadRequest:request];

2.取出cookie

- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{
    NSArray *nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];NSHTTPCookie *cookie;
    for (id c in nCookies){
        if ([c isKindOfClass:[NSHTTPCookie class]]){
            cookie=(NSHTTPCookie *)c;
            NSLog(@"%@: %@", cookie.name, cookie.value);}
    }
}

3.清除cookie

    NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray *cookieArray = [NSArray arrayWithArray:[cookieJar cookies]];
    for (id obj in cookieArray) {
        [cookieJar deleteCookie:obj];
    }
