網(wǎng)上百度了好多方法,都沒有達到自己需要的,最終還是自己搞出來,只要針對保存taoBao的cookies;

/* 在加載webView的時候 將cookie設置到url中

• (void)loadWebView {
  NSString *urlString = @"******";

  NSURL * url = [NSURL URLWithString:urlString];

  //獲取本地保存的 cookies
  [self getCookiesForUrlWithRequest:url];

  NSURLRequest * request = [NSURLRequest requestWithURL:url];

  [self.webView loadRequest:request];

}

• (void)getCookiesForUrlWithRequest:(NSURL * )url {
  NSMutableArray * cookiesLocation = [NSMutableArray arrayWithCapacity:10];
  NSArray *cookDics =[[NSUserDefaults standardUserDefaults] objectForKey:@"cookies"];
  for (NSDictionary *cookies in cookDics ){
  if ([cookies isKindOfClass:[NSDictionary class]]) {
  NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"name"]] forKey:NSHTTPCookieName];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"version"]] forKey:NSHTTPCookieVersion];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"value"]] forKey:NSHTTPCookieValue];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"expiresDate"]] forKey:NSHTTPCookieExpires];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"domain"]] forKey:NSHTTPCookieDomain];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"path"]] forKey:NSHTTPCookiePath];
  [cookieProperties setObject:[NSString stringWithFormat:@"%@",cookies[@"isSecure"]] forKey:NSHTTPCookieSecure];

      //  將字典轉化為cookie
        NSHTTPCookie *cookieuser = [NSHTTPCookie cookieWithProperties:cookieProperties];
        [cookiesLocation addObject:cookieuser];
    }
  

  }
  [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookiesLocation forURL:url mainDocumentURL:NSHTTPCookieAcceptPolicyAlways];
  }
  /// mainDocumentUR 枚舉 : NSHTTPCookieAcceptPolicyAlways， NSHTTPCookieAcceptPolicyNever免姿， NSHTTPCookieAcceptPolicyOnlyFromMainDocumentDomain
