Over the past six years, I’ve done a lot of iOS development (and written a lot about iOS). I would say it’s been the primary focus of my career. But as a software consultant, I need to be flexible, and I’ve done my fair share of Android development as well. I’m currently working on a […]
When you use the WKWebView control to render a web page in your iOS application, it doesn’t come with the usual browser controls that users may expect. It renders the webpage without a toolbar or functions like Back, Forward, or Reload. I’m going to show you how to use the iOS UIRefreshControl to reload a […]
As I age, my ability to see small text on my iPhone gets worse. The Dynamic Type feature allows iPhone users to make the text larger on their iPhones. In this blog post, I will show you how to get Dynamic Type to work with a static UITableView.
The design for a recent project called for the contents of the popover view to be emphasized prominently. Specifically, the design wanted all the views behind the popover to be dimmed. By default, iOS will put a radial gradient around the popup to draw attention to it, but I needed something more. In this blog […]
On a recent project, I had to add a gradient background to a UINavigationBar. At first, I thought it would be easy, but I soon discovered a problem when I rotated my device to landscape orientation and the gradient on the navigation bar did not resize.
With the dawn of the Internet of Things, smart homes, and connected devices, mobile apps have become key elements of creating harmony between everything. Most IoT devices require users to provision their devices on a home wireless network, which can sometimes cause poor user experience. However, apps have the ability to ease these pain points […]
When I first started using ReactiveCocoa (now ReactiveObjC), I mainly stuck to the basic operators: map, flatten, merge, etc. I saw a few examples of createSignal, but all I saw was a lot of manual work with disposables, subscribers, and other tedious sorts of things that I didn’t really want to mess with.
The fourth item in my Swift Tool Belt is an extension for UITableViewController. A UITableViewController is a view controller with a table view that takes up the entire screen. My extension provides a couple of methods to resize the header and footer of a table view.
The third item in my Swift Tool Belt is a couple of extensions on UILabel. These extensions will allow easy access to modify the edge insets on a label (the extra padding all around the text). There’s also an extension to add a rotation transform to a label. All of these extensions will be IBDesignable […]
The second item in my Swift Tool Belt is an extension on the Date class. The interface to the Date class in iOS is very powerful, but in my opinion, it is not very readable. Simple operations to add/remove time to a date can be several lines long. Many of my extensions help with the […]
