How to create and manage session in iphone app?
提问by Shaunak
I have an application which uses wcf web service and after successful login, i want to activate a session of 10 minutes. If user is idle or app is in background for 10 minutes then session should expire and app should ask for login details again.
我有一个使用 wcf Web 服务的应用程序，成功登录后，我想激活 10 分钟的会话。如果用户空闲或应用程序在后台运行 10 分钟，则会话应过期，应用程序应再次询问登录详细信息。
I have used keychain for storing username and password and it works But i want to add the session so that user is redirected to main page if session is not expired and to the login page if session is expired...
我已经使用钥匙串来存储用户名和密码并且它可以工作但是我想添加会话，以便在会话未过期时将用户重定向到主页，如果会话已过期则重定向到登录页面...

我知道这是一个重复的问题，但我不得不写它，因为我没有从其他问题中得到正确的答案。请帮忙..

如果用户以这种方式单击注销删除所有数据，则在仪表板注销按钮中。
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults removeObjectForKey:@"username"];
[defaults removeObjectForKey:@"password"];
