What other precautions need to take care of, while uploading iOS app on app store developed by using Material Library
Thanking you,
There are no precautions you need to take. You should not have an issue publishing an app with Material.

We were doing survey like web app in rails framework adding API functionality to support iOS and Android in future.
Recently I learned about firebase and I really liked it. It fits for iOS and Android very well. I am not sure does it fit for web.
My plan is to use Angular4+Ionic+Firebase frameworks to build hybrid app.
Then to build web app using Angular4+Firebase. As far as i know implementing whole business logic in frontend is not secure in N-tier architecture. Because survey results will be calculated in front end.
Simply I want to use firebase for web app:
There are two options for me. Not sure which one is more preferred.
1. Angular4+Firebase
2. Angular4 + Nodejs + Firebase
Can you suggest preferred way to build web app using firebase?
Firebase is a serveless technology, however you can use Firebase Cloud Functions to keep your business rule.
you can use Angular 4 as your Frontend, Node as your backend to create WebApis, and FireBase to store your data as it can work as Realtime Database
I want to develop Mobile App using Node.js and Html5/Bootstrap as frontend?
I searched the web , but not getting any proper source of look. I am New in Node.js , but i Know HTML5 / Bootstrap.
Can anyone Guide me through to Develop Mobile App using these two?
While this is an opinionated question/answer and shouldn't be on SO, I'll share my experience as I was in the same boat recently:
For the front-end (The app): Look up PhoneGap (Apache Cordova) to get an idea about building cross-platform mobile apps using HTML5/CSS/JS. Keep in mind that you can use a good amount of front-end frameworks to ease your workload (AngularJS, Framework7, jQuery, etc.)
For the back-end (Server): Node.js is a great start, however you'll need to code your backend almost from scratch this way. I suggest looking up "Parse Server" to use it for your backend. It's an open-source solution for mobile apps backends (MBaaS). If you still decide to code your own full backend, then I highly recommend learning MEAN stack (MonogoDB, Express.js, AngularJS, Node.js), it might take you a while, but the portable experience you'll get is huge.
Either way, if you want to make high performing apps, it's always recommended to go native (Android apps using Java and Android Studio, iOS apps using XCode and Swift)
I hope this helps,
Best of luck
I'm planning to build a hybrid mobile app,
I have already progressed pretty well with the server-side using Express 3, and PAssport for authentication.
Now I need to make a decision on what framework or library to use for the clinet-side.
I was wondering if I could get some recommendations and perhaps pros and cons of going with frameworks like
Sencha Touch, JQuery Mobile, Phonegap....
and if there is anyother ones that you think it's worth considering please mention them here,
Thanks for any pointers or advice
JQuery Mobile and Sencha Touch are JavaScript libraries that will let you create an HTML5 application that looks like a native application. Cordova/Phonegap lets you wrap your HTML5 app in native code and provides a common JavaScript API that gives you access to native functionality, like taking a picture with the camera or getting the users Contacts. Another benefit of using Cordova is that it creates native applications for you using the same HTML5 app, so you can publish these files to App stores and increase your distribution. With a JQuery/Sencha Touch only app, you can't distribute on app stores because your hybrid app is simply a website (so, I guess it'd only be a mobile app.)
There are hundreds of blog posts comparing different JavaScript frameworks like Sencha vs jQuery vs Dojo, so you should just go off and do some of that reading. Personally I would suggest Dojo as I think it is the most powerful and enterprise ready framework, but it can have a steep learning curve. One thing I like about Dojo though is the build system, you can pick and choose the modules you want so that you don't have to end up including an enormous .js file like JQuery. I have no idea if jQuery can do this, but a lot of user apps I have seen that use Cordova and JQuery end up including all of jQuery and then jQuery mobile.
If you want to access native device features and/or package the web app as a native app and distribute it on the stores, you should use one of those JavaScript frameworks in combinations with Cordova. (Cordova is the new name for PhoneGap.) Phonegap/Cordova is not really used to build mobile web apps, it's used to extend the capabilities of mobile web apps and allow them to access native device functionality in a completely cross platform way.
Ionic is a new framework available for making hybrid apps that I am liking a lot so far. The framework is built with Sass and AngularJS on top of PhoneGap. Ionic just handles the front end so you still build your app with PhoneGap. I found that since it uses AngularJS your javascript code ends up being a lot cleaner and you will save development time making your app slick compared to what you would have to write with jQuery. It also has some beautiful UI elements. The ionic team has done a lot of speed optimizations with the framework so your app will feel more native than your typical hybrid app built purely with PhoneGap. The framework is still in alpha but I have been impressed with it.
So I'm in the process of developing an iOS app and I wanted to use the Spotify web API for searching and looking up songs in Spotify. However, I can't really tell if that is how to do it or if there would be better ways to do it and wanted to clarify before I began. Thanks in advance!
If you'd like the use the Web API, it works just the same as any other JSON REST API, so a lot of the tutorials out there for doing that on iOS will help you just fine. For converting between JSON and Objective-C data structures, newer iOS versions have NSJSONSerialization, otherwise I can recommend the open-source TouchJSON.
Also, you might want to look at CocoaLibSpotify, which is an Objective-C library for interacting with the Spotify service in a much more integrated way than the Web API — including music streaming. However, it does require a Spotify user be logged in to use.
I had a bunch of apps that worked great in iOS 4. None of them work in iOS 5 (thanks Apple). I haven't been developing recently, and I don't have the time or knowledge to make my apps compatible with iOS 5. My question is, is there a way to make the apps available only to people running iOS 4? or do I have to just remove them from the app store? I don't want people to download my apps and have them not work. Thanks.
I believe you can set such restriction for people who are downloading your app from a computer (the app won't show up in iTunes). However, if the user is viewing the store through their iDevice, I think they can find your app and download it nonetheless.
It should suffice to simply put in the description that the app won't work with iOS 5.
Or, perhaps you should take a little look into why is your app not working. Normally the problem is not so big.
