问题描述
我有一个UIWebView，我不想它存储一个cookie，所以就在webview加载之前，我做：
I have a UIWebView, and I don't want it to store an cookies, so just before the webview is loaded I do:
NSArray* cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
for (NSHTTPCookie *cookie in cookies) {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
}
检查Cookie的计数为0，因此它们都将被删除。但是当我去stackoverflow它仍然识别我的Google帐户和登录我。这是怎么回事？
Checking the count of cookies is 0 so they are all deleted. But when I go to stackoverflow it still recognizes my Google Account and logs me in. How does this happen? I though it worked with cookies?
推荐答案
我必须处理完全相同的问题，我发现了两种方式来处理问题。
我首先注意到，cookie得到（有时）设置为奇怪的时候（奇怪的行为，特别是与ios 4.0）。
I had to deal with the exact same issue and I found 2 ways to deal with that problem.I first noticed that cookies get (sometimes) set at weird times (Strange behaviour especially with ios 4.0).
然后，我集成了持久化，手动标记在注销（又名清除所有Cookie /删除其他用户数据）操作上设置为True。
在下次登录时（又称为基于用户登录的操作）我再次清除Cookie（与您在代码帖中所做的操作相同）。
I then integrated a persistant, manual flag that was set True on a "logout" (aka clear all cookies / delete other user data) action.upon the next login (aka user-login-based action) I cleared the cookies again (the same way you did it in your code-post).
后来我发现，听到 NSHTTPCookieManagerCookiesChangedNotification ，然后删除cookie工作非常好。
Later I found out, that listening to NSHTTPCookieManagerCookiesChangedNotification and then deleting cookies worked really well too.
希望我能帮助。
