UIWebview中设置Cookie,有时候设置Cookie的参数根据后台的要求而不同，我这里设置的参数是userID和userPass，即用户ID和密码

-(void)setUIWebviewcookie{
        NSString * strID = [NSString stringWithFormat:@"%@",[[UserInfoManager shareUserInfoManagerWithDic:nil] id]];
        NSURL *cookieHost = [NSURL URLWithString:@"http://www.xxx.com"];
        // 设定 cookie
        NSHTTPCookie *cookie1 = [NSHTTPCookie cookieWithProperties:
                                 [NSDictionary dictionaryWithObjectsAndKeys:
                                  [cookieHost host], NSHTTPCookieDomain,
                                  [cookieHost path], NSHTTPCookiePath,
                                  @"USER_ID",  NSHTTPCookieName,
                                  strID, NSHTTPCookieValue,
                                  nil]];
        
        // 设定 cookie
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie1];
        NSString * mdStr = [UserInfoManager md5:[UserInfoManager md5:str]];
        // 定义 cookie 要设定的 host
        // 设定 cookie
        NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:
                                [NSDictionary dictionaryWithObjectsAndKeys:
                                 [cookieHost host], NSHTTPCookieDomain,
                                 [cookieHost path], NSHTTPCookiePath,
                                 @"USER_PASS",  NSHTTPCookieName,
                                 mdStr, NSHTTPCookieValue,
                                 nil]];
        // 设定 cookie
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];       
}

在网络请求中设置Cookie
/**

• 网络请求设置Cookie
  */
  -(void)setCookie{

  NSString * cookStr = [NSString stringWithFormat:@"这是字符串是后台要求的"];
  NSMutableDictionary cookieProperties = [NSMutableDictionary dictionary];
  [cookieProperties setObject:@"author" forKey:NSHTTPCookieName];
  [cookieProperties setObject:cookStr forKey:NSHTTPCookieValue];
  [cookieProperties setObject:@"www.xxx.com" forKey:NSHTTPCookieDomain];
  [cookieProperties setObject:BaseURL forKey:NSHTTPCookieOriginURL];
  [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
  [cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];
  [cookieProperties setValue:[NSDate dateWithTimeIntervalSinceNow:606024360] forKey:NSHTTPCookieExpires];
  NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
  [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
  }

```codelang
/**
 *  清除Cookie
 */
-(void)clearCook{
    NSHTTPCookieStorage *cookieJar = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray *_tmpArray = [NSArray arrayWithArray:[cookieJar cookies]];
    for (id obj in _tmpArray) {
        [cookieJar deleteCookie:obj];
    }
}

这些都是手动设置的Cookie，AFNetworking也可以设置，由于没时间研究，就介绍到这里吧
