在
This Question中说,AFNetworking在后台自动处理cookies,但是在
Previous问题中,我遇到麻烦,在登录时在PHP服务器上保持会话.一旦关闭(停止调试在Xcode)的应用程序,并回到会议已经没了.答案是保持像这样的cookie来解决问题：
NSData *cookiesData = [[NSUserDefaults standardUserDefaults] objectForKey:@"User"];
if ([cookiesData length] > 0) {
for (NSHTTPCookie *cookie in [NSKeyedUnarchiver cookiesData]) {
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
}
}
当我尝试做这样的事情时,这给我一个应用程序崩溃.当我登录时,我设置了NSUserDefault：
[[NSUserDefaults standardUserDefaults] setObject:data forKey:@"User"]; //Then synthesize
解决方法
使用以下内容,这是保存和加载适用于我的Cookie的正确方法：
- (void)saveCookies{
NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject: cookiesData forKey: @"sessionCookies"];
[defaults synchronize];
}
- (void)loadCookies{
NSArray *cookies = [NSKeyedUnarchiver unarchiveObjectWithData: [[NSUserDefaults standardUserDefaults] objectForKey: @"sessionCookies"]];
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in cookies){
[cookieStorage setCookie: cookie];
}
}
希望有帮助！
