var main = plus.android.runtimeMainActivity();  
var pkName = main.getPackageName();  
var NotificationManagerCompat = plus.android.importClass("android.support.v4.app.NotificationManagerCompat");  
var packageNames = NotificationManagerCompat.from(main);  
console.log(JSON.stringify(packageNames));  
if (packageNames.areNotificationsEnabled()) {  
    console.log('已开启通知权限');

        success: function (res) {  
            if (res.confirm) {  
                var Intent = plus.android.importClass('android.content.Intent');  
                var intent = new Intent('android.settings.APP_NOTIFICATION_SETTINGS');//可设置表中所有Action字段  
                intent.putExtra('android.provider.extra.APP_PACKAGE', pkName);  
                main.startActivity(intent);  
            }  
        }

IOS

var UIApplication = plus.ios.import("UIApplication");  
var app = UIApplication.sharedApplication();  
var enabledTypes  = 0;  
if (app.currentUserNotificationSettings) {  
    var settings = app.currentUserNotificationSettings();  
    enabledTypes = settings.plusGetAttribute("types");  
} else {  
    //针对低版本ios系统  
    enabledTypes = app.enabledRemoteNotificationTypes();  
}  
plus.ios.deleteObject(app);  
if ( 0 == enabledTypes ) {  
    uni.showModal({  
        title: '提示',  
        content: '请先打开APP通知权限',  
        showCancel: false,  
        success: function (res) {  
            if (res.confirm) {  
                var UIApplication = plus.ios.import("UIApplication");  
                var NSURL = plus.ios.import("NSURL");  
                var setting = NSURL.URLWithString("app-settings:");  
                var application = UIApplication.sharedApplication();  
                application.openURL(setting);  
                plus.ios.deleteObject(setting);  
                plus.ios.deleteObject(application);
