答
我使用 ASIHTTPRequest 库与我的Web服务进行通信.
I use the ASIHTTPRequest library to communicate with my webservice.
它具有处理cookie的内置功能，因此我只需使用POST请求登录，就可以像设置普通浏览器一样设置cookie.
It has built-in capability to handle cookies, so I simply login with a POST request and the cookie is set like a normal browser.
当网络连接断开时，您仍然可以检查有效的cookie:
When your network connection is down, you can still check for a valid cookie:
- (BOOL) hasSignInCookie
{
NSArray *cookieJar = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
for( NSHTTPCookie *cookie in cookieJar)
{
if( [[cookie name] compare: @"JourneyTagID"] == NSOrderedSame)
{
return YES;
}
}
return NO;
}
