Apple added a touch-sensitive layer to the screen of the brand new iPhone 6s (plus). With the coming of this new screen, they’ve added some new UI interactions like application shortcuts and peek and pop.
In this 3D touch peek and pop tutorial I will learn you how to implement this new way of interacting with your content by building a photo gallery. When you press hard on the screen you’ll see a preview of the image and if you press really hard the preview will pop into a detail view.
At the end of this tutorial I’ll show you how to add preview actions. This way you can interact with the content without going to the detail view. You can do this by swiping up while you are previewing the content.
A few years ago Apple introduced TouchID on the iPhone5S. Instead of asking your user for a password, you can just ask for their fingerprint (if their device has TouchID) which improves the UX by a gazillion times.
With the introduction of iOS7, it was impossible for a developer to use the fingerprint sensor for authentication. Luckily in iOS8, Apple provided us with an API to do so.
In this tutorial I’ll show you how you can integrate TouchID authentication in your application.
With the introduction of the iPhone 6S (plus), Apple added a pressure-sensitive layer to their screen. This creates a bunch of new UX possibilities for creating apps. It’s possible to do a hard press on an application icon and get shortcuts which take you to a specific point in your app. For example, if you do a hard-press on the Photo’s app icon you can quickly search for an image, check the most recent images or see your favourites. It’s also possible to make these quick actions dynamic, meaning that you can add and remove actions based on the state of your application.
In this tutorial I will show you how you can add these quick actions to your application icon.
Last year I published TNCheckboxGroup for Objective-C, but I had a few comments it didn’t work when using with Swift. So I just published a Swift version on Github. This versions leverages UICollectionView to handle big sets of checkboxes. TNSwiftyCheckboxGroup, create checkbox groups in Swift.
For a project I needed to add a UIPickerView with custom cells using AutoLayout. UIKit allows this via the UIPickerViewDelegate method pickerView(_:viewForRow:forComponent:reusingView).
The cell just needed an UIImageView and UILabel, so I thought it would be pretty straightforward to do, but there are some caveats you need to know. Big thanks to Tom Adriaenssen for pointing them out and not ruining my Sunday afternoon 🙂
