Quite often it’s required from iOS applications to be capable of performing search in specific data that is displayed in a tableview. Undoubtably, most of developers have faced that situation, and the most usual approach to that is to use the default controls that the iOS SDK provides. Up to iOS 8, Apple was providing a special control for performing searches in tableviews named UISearchDisplayController. This controller, in conjunction with the UISearchBar was making possible to add search features quite easily in an application. Nevertheless, this belongs to history now.
In my last tutorial we worked with the YouTube API, and through the demo application we managed to make requests to that specific Google API. Actually, we created an API key prior to any request, as that key was vital for every request that was about to return data back to our application. This time, we’ll continue working with the Google APIs, and my goal is to show you how to make authorized requests after a user has signed in with the Google in the application.
It’s a well-known fact that Google provides a big number of electronic products and services that can be used from the simplest end-user, to the most sophisticated one. But further than those who just use the Google services as they’re provided, there are people who need to have a different kind of access to them; [...]
In a world that there are extremely so many mobile applications, there is no doubt that it’s tremendously difficult to create new ones that will attract users’ attention and will make their way among all others up to the top successfully. Definitely, one could say that a secret ingredient that turns simple apps to outstanding [...]
Many applications today provide the option to get extra content and features by making purchases through them. This technique, known as In-App Purchases, has become a fashion during the last few years, and it has proven to be quite profitable and efficient. Undoubtably, we all have downloaded apps from App Store that gave us the [...]
Finding integrated cloud services into an iOS application some time ago was something quite rare. There were not many services offering APIs to do that, and moreover just a small percentage out of the total users had a constant Internet connection (3G/4G connections, or constant access to Wifi networks). Nowadays things have dramatically changed, as [...]
One of the first tutorials I contributed here at Appcoda was a guide about how to create a QR code reader in iOS. At that time of course, the code of that tutorial was written in Objective-C, as Swift wasn’t still existing. Later in time, my friend Simon wrote a new one, this time made [...]
One of the greatest tasks that developers have to perform, is to find and implement a proper way to store the application data. Undoubtably, there’s no application in any platform that doesn’t need to save some kind of data at some point. Depending on the nature of the application usually, the amount of data that [...]
Working with maps in iOS consists of an entire programming chapter, as there are tons of things that a developer can do with them. From just presenting a location on a map to drawing a journey’s route with intermediate positions, or even exploiting a map’s possibilities in a completely different way, dealing with all these [...]
Since the introduction of iBeacons with iOS 7 by Apple, a lot of things have been said and written about. iBeacon technology consist of a revolutionary way to keep track of the position of a device indoors and use location services, similarly to the GPS outdoors, and it’s based on the signal transmitted through Bluetooth [...]
