I am trying to add the instant search functionality into my existing controller using the UISearchBar or
UISearchController
When user enters 3 characters on searchbar, should start fetching the data & show in the tableview. For that I added the API call on searchBar Delegate, but it takes time to fetch the data , while user again start entering the data, each time user enters a character , it hits one api.
What approach should we follow to achieve it ?
Is there any good library or open source to do it?
You can use InstantSearch iOS, which is an open-source library providing UI components to help you easily build instant search experiences on iOS with Algolia.
It is available on GitHub. See for example the InstantSearch E-commerce app:
You can start with the Getting Started Guide which will take you through the main steps to use the library.
The example application is also a great addition to the guide as it’ll help you get an idea of what you can build with InstantSearch iOS.

I am trying to log in to the app using two options one is OTP based and the other is QR based. I am looking for an option where I can have multiple AWSconfiguration.json files in one project and the AWSMobileClient can choose from one depending on the type of login in the Login View controller. I tried solutions given on some of the StackOverflow links but unfortunately, not getting the expected result.
Thanks In Advance
I've recently installed Walmart's API into my iOS app. The app's purpose is for the user to search for items using Walmart's API and then display the queried items to the user. However I am having a hard time finding any examples on how to use Walmart's API with Xcode and Swift language. Was curious if anyone could point me in the direction of how to properly use the API while using Swift language or if anyone has experience using the Walmart API in Xcode? I feel like it shouldn't be hard to accomplish what I am trying to do but right now I am a bit lost. All help and advice is appreciated in advance! Thanks.
Whenever An API is Created The Author gives out a Documentation, about the usage of the API, Requests Parameters etc.
So, Go through the Documentation of Your Needed API,
Once the Requests Are made in-app, they Generally respond you in JSON, XML etc.
Using these Incoming data you can Populate data in your APP
I'm still a newbie in react native and it's also my first time using Firebase database. So, using the official documentation i've managed to add items (composed only by title ) in the database but only using an alertIos.
Now I need to navigate to other screen, add items and I need the items themselves composed by title and genre for example. Thank you
PS: here is the tutorial that i used : https://firebase.googleblog.com/2016/01/the-beginners-guide-to-react-native-and_84.html
Also, I used a workaround when accessing to the Firebase database : i changed the rules to read and write for everybody (thing I'm sure is wrong), so can you help me access in a secure way.
I was wondering if anyone could point me to any useful tutorials on allowing a master user to update information for their app. I am looking into creating an application for a local restaurant and I want the owner to be able to update information like the soup of the day and such by themselves.
I have been looking into JSON and CMS for this, but I am unable to find any useful information regarding iOS 8 or xCode 6. If anyone could provide me with this information, or any other suggestions on how to achieve this I would be very grateful!
(I am using Swift not Objective-C)
This is not a code issue, rather it is a development concept issue. You have many choices including making an API that is updated by the restaurant. The app then connects to the API and gets the recipes. If you feel you need to do this via the App make a special username that is allowed access to modify the menu. This can be accomplished via matching username exactly or via using a regex. It all really depends on the structure of your app platform.
How Can I Incorporate my WordPress Blogs into an iOS app? I have a beautiful word press site and I want to create a native iOS app. I have knowledge of coding for iOS, but I just don't know how I would go about showing all the latest blogs that are up in a beautiful way.
Thanks in Advance!
There are many ways you can achieve that. Here is a list of things you need to do in order to make an iOS app for your WordPress blog:
1) You need to parse the data from your WordPress blog to display it inside your iOS app. You can do it by parsing your blog's RSS feed you can parse JSON.
2) If you are planning to parse the RSS feed, use NSXMLParser to do that. There are other third party libraries available that parse the XML feeds but i would suggest to go with the built in NSXMLParser as there is plenty of help available online for it.
3) If you are planning to parse JSON data, install Feed JSON plugin on your WordPress blog. Once installed, you can go to http://example.com/feed/json to get the JSON data. (You can replace example.com with your blog's URL)
4) To connect to the web services like XML feed and JSON on your blog, you can use third party libraries like AFNetworking or you can use Apple's built in libraries like NSURLConnection and other classes to connect and download the data from the webservice.
5) Here are some very easy tutorials for the steps above. How to Use NSURLConnection, How to fetch JSON or How To Parse RSS with NSXmlParser
You can start your app by completing the above steps and getting started.
6) After that one of the most important thing is to download images asynchronously in the UITableViewCells where you are displaying your blog posts. I would suggest you to download a video from Stanford University's iOS programming course on iTunes U that shows how to do it or you can simply find some tutorials or look for questions on StackOverflow.
7) Then you have to create a UIWebView and when the row of any blog post inside the UITableView is tapped, you can use the link to segue in the UIWebView to show the actual blog post. You can use didSelectRowAtIndexPath in order to pass data between view controllers.
8) Below the view controller that contains the UIWebView, you can add functions like stop, refresh, sharing on Facebook and Twitter etc.
9) As you can see that is a lot of work and business people just think that its easy to develop an iOS app but the truth is that it takes some time to completely package the app and submit to the App Store. You can also outsource your project by using service like Convert WordPress Blog To iOS App that is completely for free if you share revenue with them but its your choice and i recommend you to code it yourself to have complete ownership of you app.
Rest is just a matter of choice of different functions you would like to make in your app to stand out from the rest. You can add a Facebook style sliding navigation controller on the left side to create and parse specific categories on your blog, you can use Flipboard style swiping in your Web View etc etc. For that stuff there are a lot of third party libraries available.
Hope this helps!
You can read an answer of mine about cloud based ios apps (the db is online) here:
press me
now as i said, to get info from the server you need to use JSON, in wordpress there is a very good and simple plugin for that: JSON API
now the use of that is simple, you can see it in the notes: http://wordpress.org/plugins/json-api/other_notes/
but for example for getting the last posts in the system you need to run the url: http://www.example.org/api/get_recent_posts/
The /api means it's the plugin (you can change that in the settings) and the /get_recent_posts/ is the function.
there are many other functions like this one for everything you need and it can get more complicated than that based on what you want to get from the db.
After running the "query" and getting a response in JSON you need to use it:
Working with JSON in iOS 5 Tutorial
now for the running of the url i recommend to use AFNetworking
now all you need to do is use the json string you get for getting out info.
this would have some more issues like managing html codes you get in the content respons and so but it's the start, develop your way up :)
