This year’s WWDC was full of surprises for developers. Apple chose the path of opening so many aspects of iOS to developers, which is something that we could not even think of some years ago. Users download more and more apps and spend more and more time on their smartphones. Apple aims to help this by eliminating the number of times users have to open apps and find what they want.
One of the most popular posts in my blog is the tutorial for creating a Pop-up window with iOS SDK using Objective-C. Since then many readers reached me out asking for a Swift version of the Pop-up. In general the process is exactly the same in Swift (except the language used to write the code of course…), so I am not going to dive into the process of creating the .xib files again.
In WWDC 2013, Apple introduced Xcode 5 and iOS SDK 7 with a built in framework for testing: XCTest.framework. Unfortunately Apple documentation lacks details for this framework. In this post I am going to present a simple way to test a UITableView using XCTest framework.
In an iOS project I am currently working on, I got a request to create a pop-up window. Trying to figure out how to do it, I came up with a solution that is pretty easy to implement and very straight forward. All you need is a view controller with a transparent background and a subview (your popup window). After creating the popUpViewController, you can just call it from any other view controller.
When coding for iOS, I usually style images with shadows show the layout looks more elegant. Adding shadows is easy, but when it comes to adding borders to UIImageViews things become trickier. That’s because when adding a border to a UIImageView, this border hides info from the image. To solve this issue, we have to rescale the image and then add the border to the scaled image.
