UITABLEVIEW IN AN APPLE WATCH APP

Image
In this post I’m going to show you how to create a  WKInterfaceTable  and set dynamic content in a list in a Watch app. Let’s start by creating a new project. Open Xcode 7.0 (or later) and click on  File > New > Project  (as shown below). Next, select the  iOS App  with WatchKit App option and click Next (as shown below). Enter the Product Name – this will be the name of your application. I’ve used the name ‘ MyFirstWatchApp ’. Click Next and choose the appropriate destination for creating the project. When you do that, XCode will automatically create a number of files and directories. Open the Interface.storyboard file under “ WatchKit App ”. Then, drag the  WKInterfaceTable  from the Object library to the  Interface Controller  (as depicted below). Now, drag the  WKInterfaceLabel  from the Object library to the newly created Table Row C...
