WatchKit Catalog is an exploration of the UI elements available in the WatchKit framework. Throughout the sample, you'll find tips and configurations that will help guide the development of your WatchKit app.
-
Glance and Notification schemes have been created for ease of switching between executables on the fly. In your projects, edit the WatchKit app scheme and change the Executable to the specific executable you'd like to run and debug. You can additionally create additional schemes, as this sample has.
-
To debug the Glance or notifications in the iOS Simulator, select the appropriate scheme in the Xcode toolbar and then Build and Run.
-
Tapping the Glance will launch the WatchKit app. In AAPLGlanceController, -updateUserActivity:userInfo:webpageURL: is called in -willActivate and takes advantage of Handoff to launch the wearer into the image detail controller (AAPLImageDetailController). When the WatchKit app is launched from the Glance, handleUserActivity: is called in AAPLInterfaceController. AAPLImageDetailController will be pushed to, as its controller's Identifier string is passed in the userInfo dictionary.
-
AAPLButtonDetailController has two examples of how to hide and show UI elements at runtime. First, tapping on button "1" will toggle the hidden property of button "2." When hiding the button, the layout will change to make use of the newly available space. When showing it again, the layout will change to make room for it. The second example is by setting the alpha property of button "2" to 0.0 or 1.0. Tapping on button "3" will toggle this and while button "2" may look invisible, the space it takes up does not change and no layout changes will occur.
-
In AAPLImageDetailController, note the comments where the "Walkway" image is being sent across to Apple Watch from the WatchKit Extension bundle. The animated image sequence is stored in the WatchKit app bundle. Comments are made throughout the sample project where images are used from one bundle or another.
-
In the storyboard scene for AAPLGroupDetailController, note the use of nested groups to achieve more sophisticated layouts of images and labels. This is highly encouraged and will be necessary to achieve specific designs.
-
AAPLTableDetailController has an example of inserting more rows into a table after the initial set of rows have been added to a table.
-
AAPLControllerDetailController shows how to present a modal controller, as well as how to present a controller that does not match the navigation style of your root controller. In this case, the WatchKit app has a hierarchical navigation style. Using the presentation of a modal controller though, we are able to present a page-based set of controllers.
-
AAPLControllerDetailController can present a modal controller. The "Dismiss" text of the modal controller is set in the Title field in the Attributes Inspector of the scene for AAPLPageController.
-
AAPLTextInputController presents the text input controller with a set of suggestions. The result is sent to the parent iOS application and a confirmation message is sent back to the WatchKit app extension.
- Updated Handoff API in Glance.
- Added WatchKit app icon.
- Modified controllers to use images from the asset catalog in the WatchKit Extension.
- Added example of setting the color and title for a switch.
- Added example of a label using semibold font weight in Interface Builder.
- Added example of a label using ultralight font weight programmatically.
