现在我有个APP是嵌入的webView 登陆需要记住用户名和密码下次自动登陆，求大神看看如何实现？谢谢
目前这个问题我已经解决了，希望有用到的朋友来这里看http://www.jianshu.com/p/9bf9...：给颗心
另我把代码写到这里一份也：
1、在UIWebView的代理方法中实现获取cookies并将cookies放到NSUserDefaults保存起来

  - (void)webViewDidFinishLoad:(UIWebView*)webView{
    NSArray*nCookies = [[NSHTTPCookieStoragesharedHTTPCookieStorage]cookies];
    NSHTTPCookie*cookie;
    for(idcinnCookies)
    {
    if([cisKindOfClass:[NSHTTPCookieclass]])
    {
    cookie=(NSHTTPCookie*)c;
    if([cookie.nameisEqualToString:@"PHPSESSID"]) {
    NSNumber*sessionOnly = [NSNumbernumberWithBool:cookie.sessionOnly];
    NSNumber*isSecure = [NSNumbernumberWithBool:cookie.isSecure];
    NSArray*cookies = [NSArrayarrayWithObjects:cookie.name, cookie.value, sessionOnly, cookie.domain, cookie.path, isSecure,nil];
    [[NSUserDefaultsstandardUserDefaults]setObject:cookiesforKey:@"cookies"];
    break;
    }
    }
    }
    }

2、获取cookies：运行之后，UIWebview加载url之前获取保存好的cookies，并设置cookies，

NSArray*cookies =[[NSUserDefaultsstandardUserDefaults]objectForKey:@"cookies"];
NSMutableDictionary*cookieProperties = [NSMutableDictionarydictionary];
[cookiePropertiessetObject:[cookiesobjectAtIndex:0]forKey:NSHTTPCookieName];
[cookiePropertiessetObject:[cookiesobjectAtIndex:1]forKey:NSHTTPCookieValue];
[cookiePropertiessetObject:[cookiesobjectAtIndex:3]forKey:NSHTTPCookieDomain];
[cookiePropertiessetObject:[cookiesobjectAtIndex:4]forKey:NSHTTPCookiePath];
NSHTTPCookie*cookieuser = [NSHTTPCookiecookieWithProperties:cookieProperties];
[[NSHTTPCookieStoragesharedHTTPCookieStorage]setCookie:cookieuser];

注意：要在[self.webView loadRequest:req];之前设置获取cookies！
