iOS怎么判断用户是否打开了系统设置里面推送通知的开关  求大神指点........

我是这么判断的  但不管设置没设置都会弹出警告说没有设置

这是我用的方法

if(isIOS8){

        BOOL isRemoteNotify = [UIApplicationsharedApplication].isRegisteredForRemoteNotifications;

        [self shareNotificationCheck:!isRemoteNotify];

    }

    else{

        UIRemoteNotificationType type = [[UIApplicationsharedApplication] enabledRemoteNotificationTypes];

        int typeBadge = (type & UIRemoteNotificationTypeBadge);

        int typeSound = (type & UIRemoteNotificationTypeSound);

        int typeAlert = (type & UIRemoteNotificationTypeAlert);

        BOOL ret =  !typeBadge || !typeSound || !typeAlert;

        [selfshareNotificationCheck:ret];

    }

 其中［self shareNotificationCheck:YES ］是弹出警告框的
