1.獲取登錄時的cookie并保存。

NSHTTPCookieStorage? *cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];? ? ? for(NSHTTPCookie*cookie in [cookies cookies])

?{

????????[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];// 保存

? }

2.取出cookie，并添加到webView的請求頭。

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:HOST]]; // 這里的HOST是你web服務器的域名地址

for (NSHTTPCookie *cookie in cookies)

{

?// cookiesWithResponseHeaderFields方法，需要為URL設置一個cookie為NSDictionary類型的header，注意NSDictionary里面的forKey需要是@"Set-Cookie"

?NSArray *headeringCookie = [NSHTTPCookie cookiesWithResponseHeaderFields:[NSDictionary dictionaryWithObject: [[NSString alloc] initWithFormat:@"%@=%@",[cookie name],[cookie value]] forKey:@"Set-Cookie"] forURL:[NSURL URLWithString:self.htmlUrl]];

// 通過setCookies方法，完成設置，這樣只要一訪問URL為HOST的網頁時，會自動附帶上設置好的header

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:headeringCookie forURL:[NSURL URLWithString:self.htmlUrl]mainDocumentURL:nil];

?}
