在iPhone系統升級前：10.1之前的時候我們在與H5交互直接通過傳遞cookie就可以實現H5的部分參數需求。

NSURL *cookieHost = [NSURL URLWithString:urlString];

NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];

NSString *app_Version = [NSString stringWithFormat:@"%@",[infoDictionary objectForKey:@"CFBundleShortVersionString"]];

NSHTTPCookie *cookieClient = [NSHTTPCookie cookieWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:[cookieHost host], NSHTTPCookieDomain,[cookieHost path], NSHTTPCookiePath,@"Client",? NSHTTPCookieName, @"ios", NSHTTPCookieValue,nil]];

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookieClient];

然后，從系統升級后，10.2起，cookie傳值已經無法正常傳遞過去。即H5無法收到ios平臺發送過去的cookie參數。

究其原因：IOS 10.2以后不再支持http請求協議，稱為支持的https協議，所以http的協議無法通過cookie傳遞到H5頁面。

解決方法：

新增一個字段：key:httpOnly? value：false。

NSHTTPCookie *cookieClient2 = [NSHTTPCookie cookieWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:[cookieHost host], NSHTTPCookieDomain,[cookieHost path], NSHTTPCookiePath,@"httpOnly",? NSHTTPCookieName, @"false", NSHTTPCookieValue,nil]];

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookieClient];

這時候再次運行，那么H5已經可以接收到我們的cookie值了！
