最新iOS获取通知状态并跳转设置界面设置

1、获取用户通知中心对程序消息通知的设置，是否开启消息通知

if ([[UIDevice currentDevice].systemVersion floatValue]>=8.0f) {
        UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
        if (UIUserNotificationTypeNone == setting.types) {
            NSLog(@"推送关闭");
        }else{
            NSLog(@"推送打开");
        }
    }else{
        UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
        if(UIRemoteNotificationTypeNone == type){
            NSLog(@"推送关闭");
        }else{
            NSLog(@"推送打开");
        }
    }
