+##UIWebView中使用cookie实现免登陆
+
+*最近帮忙朋友上架一个纯h5的app，就是用原生做了一层壳。
+可是发现，每次重新开启app的时候之前登录的信息就不存在了，所以就想到了要需要用刀UIWebView的cookie来获取用户数据实现免登陆。*
+
+###下面贴代码
+
+
+```Object-C
+NSArray*nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage]cookies];
+    NSHTTPCookie*cookie;
+    for(id cookies in nCookies)
+    {
+        if([cookies isKindOfClass:[NSHTTPCookie class]])
+        {
+            cookie=(NSHTTPCookie*)cookies;
+            if([cookie.name isEqualToString:@"touch_id"]) {
+                NSNumber*sessionOnly = [NSNumber numberWithBool:cookie.sessionOnly];
+                NSNumber*isSecure = [NSNumber numberWithBool:cookie.isSecure];
+                NSArray*cookies = [NSArray arrayWithObjects:cookie.name, cookie.value, sessionOnly, cookie.domain, cookie.path, isSecure,nil];
+                [[NSUserDefaults standardUserDefaults]setObject:cookies forKey:@"cookies"];
+                
+                break;
+            }
+        }
+    }
+```
