watchkit Getting started with watchkit Connecting the code with the UI

Example

Like iOS where you use @IBOutlet and @IBAction, here you could use them too.

Let's say we have a button which when clicked changes the label's text to something else.

To get started:

1. Add a WKInterfaceLabel and a WKInterfaceLabel to the InterfaceController.

2. Ctrl-Drag from the WKInterfaceLabel to InterfaceController.swift and enter the details as shown in the following picture to add an outlet property:

3. Ctrl-Drag from the WKInterfaceButton to InterfaceController.swift and enter the details as shown in the following picture to add an action method:

5. Fill the action method:

Swift

outputLabel.setText("Button Tapped!")

Objective-C

[[self outputLabel] setText:@"Button Tapped!"]

6. Run the program and tap the button to see the result.
