Adventures in Swift and iOS App Development
One of the most powerful and important controls on both wearable and mobile devices are table views. Table views come in two flavors: static and dynamic. Dynamic table views read data from a collection type and displays it. Static tables allow for a vertical scroll view with a set of controls. Static table views are …
In our first part of this series, we made a simple dynamic table for the Apple Watch. Based on some pace data when I ran the Hot Chocolate 15K, we displayed the pace I ran at the mile splits. In a real running app, I would not want to add or delete any of my …

In the last post, we looked at scroll views and static tables. There are many instances where tables filled with data at runtime are necessary. If you are familiar with UITableViewController, you may be delighted to know that WKInterfaceTable is a lot simpler to put together: there are no delegate or data sources involved. It's …

To state the obvious, The Apple Watch has very small screen real estate. There are times we need more screen space than is available. In iOS, there are scroll views. One subclass of scroll views are the table views. Table views come in two flavors: static and dynamic. Dynamic reads data from a collection type …

Apple's documentation for WatchKit is quite clear, even when it is lying. The documentation states you can have hierarchical navigation or page navigation but not both. Here's is where it lies: you can have a page-based navigation as part of a hierarchical navigation scheme. There is a special modal view version of page views, which …

In the first part in this series we implemented a modal interface in WatchKit with a segue. In this part we'll present the modal programmatically and once again set up a delegate and context for moving data between controllers. Open the project from the last lesson. Press Command-N and add a new Cocoa Touch class …

Modal views on iPhones and ipads are used for input of information that requires attention. One of the on the Apple Watch is a modal view. You cannot mix a page-based interface with a hierarchical (i.e. navigation) interface as we learned in previous lessons. You can use modal interfaces with either. In this series of …

In our lessons setting up navigation controllers on the Apple Watch, we've learned how to set up the storyboard, how to use push controllers programmatically and introduced sending data to another controller and back using contexts and delegates. In this lesson, we'll pass data when you have a segue and learn how to dismiss controllers. …
In our last lesson we set up navigation in the Storyboard and programmatically. We left off with passing data from one view controller to another using the context parameter like this: We made a context variable which we passed to the destination controller. We haven't done anything yet with the value of the context. In …
Apple WatchKit gives you a choice when it comes to navigation. You can be Page-based as we introduced in our last lesson. Another alternative, is hierarchical interfaces, which closely resemble navigation controllers on the phone. In this lesson, we'll introduce the hierarchical type of navigation by setting up a small app. Hierarchy Controllers Pages are …
