Declaration
class SHMediaItemOverview
This class uses subscripting for the data elements of a custom media item that an existing property doesn’t already represent.
Add a readable custom property by extending SHMediaItemProperty with a key for that property, and by extending this class with a property that uses the key. The following code shows the extensions for an episode number:
// Add an episode number to the list of properties.
extension SHMediaItemProperty {
static let episode = SHMediaItemProperty("Episode")
}
// Add a property for returning the episode number using a subscript.
extension SHMediaItem {
var episode: Int? {
return self[.episode] as? Int
}
}Add your custom property when you create the media item as the following code shows:
// Create a new media item and set the title, subtitle, and episode properties.
let mediaItem = SHMediaItem(properties: [.episode: 42,
.title: "Question",
.subtitle: "The Answer"])
