Since iOS7, Apple engineers introduced a new set of networking API called NSURLSession, in order to help with downloading/uploading content via HTTP or HTTPS protocols.
NSURLSession came with a lot of improved tasks which developers had to write a lot of code to handle. These tasks are:
Hello everybody, and happy new year for all of you :]
A while ago, I saw so many questions on SO enquiring about how to implement a login screen to the user before he gets to the home screen on a UITabBarController based app, same way like Pinterest, Facebook and so many apps behaving this obvious way.
So I am writing this quick tutorial to show you how to do that easily in Xcode5.
A while ago, I wrote a tutorial on ray wenderlich’s blog about Git source control management with iOS 6, if you didn’t already read it, then you should do :)
And of course, if you have an idea about a good tutorial you want me to write for you, feel free to email me, or leave a tweet.
Cool Error notice view
I came across a lot of useful libraries hosted in Github, one of them is called NoticeView.
This is a lightweight library which gives a cool style for success and error alerts. Finally, i get rid of UIAlertView for just displaying “Network error” messages.
This tutorial is to introduce you with this intuitive library through a practical example: Trying to load a URL in webview, if any error occured (example: Internet connection down), a NoticeView will be displayed instead of the UIAlertView :)
Loading URL with an UIActivityIndicator
In a previous tutorial, you have seen how to load URLs already listed in a UITableView. In this tutorial, i will be showing you how to easily use a loading indicator (UIActivityIndicator) when loading a heavy URL in the UIWebView.
Loading URLs from UITableView
One of the major use of UITabelView is to make menus where every cell perform a specific task or let you navigate to another view. The typical example is the Settings application we all know in iOS devices.
In this tutorial, you will see how to deal with a grouped UITableView so that each selected row leads you to a website address. All that done programmatically without relying to Interface Builder.
Multi-language iOS App
When you create your application for iPhone and/or iPad, one of the main features you surely take into consideration, is, which community you are intending to target? What range of languages shall your app supports?
In this tutorial, you’ll go through the basics on how to make your app multi-language.
