This is the view controller for the alarm setup popover.

  • The size of the picker font

    Declaration

    Swift

    private static let _pickerFont: UIFont

  • The padding on either side of the labels we use as picker rows.

    Declaration

    Swift

    private static let _pickerPaddingInDisplayUnits: CGFloat

  • The SFSymbols names for the play sound button.

    Declaration

    Swift

    private static let _playSoundImageNames: [String]

  • The storyboard ID for this controller.

    Declaration

    Swift

    static let storyboardID: String

  • This is the audio player (for sampling sounds).

    Declaration

    Swift

    private var _audioPlayer: AVAudioPlayer!

  • This will provide haptic/audio feedback for subtle events.

    Declaration

    Swift

    private var _selectionFeedbackGenerator: UISelectionFeedbackGenerator?

  • This aggregates our available sounds. The sounds are files, stored in the resources, so this simply gets them, and stores them as path URIs.

    Declaration

    Swift

    private var _soundSelection: [String]

  • If true, then the currently selected sound is playing. This is set or cleared by the “play sound” button.

    Declaration

    Swift

    private var _isSoundPlaying: Bool { get set }

  • This references the presenting view controller.

    Declaration

    Swift

    weak var myController: RVS_SetTimerAmbiaMara_ViewController?

  • The segmented switch that controls the alarm mode.

    Declaration

    Swift

    @IBOutlet
weak var alarmModeSegmentedSwitch: UISegmentedControl?

  • The stach view that holds the vibrate switch.

    Declaration

    Swift

    @IBOutlet
weak var vibrateSwitchStackView: UIView?

  • The vibrate switch (only available on iPhones).

    Declaration

    Swift

    @IBOutlet
weak var vibrateSwitch: UISwitch?

  • The label for the switch is actually a button, that toggles the switch.

    Declaration

weak var vibrateSwitchLabelButton: UIButton?

  • The picker view for the sounds. Only shown if the seg switch is set to sound.

    Declaration

Base Class Overrides

  • Called when the hierarchy has loaded. We set up the initial states, and all the localization and accessibility.
