MIDITimeTableMeasureView

@MainActor
open class MIDITimeTableMeasureView : UIView

Draws time table measures in its frame. Use tintColor property to change text and bar colors.

  • Number of measure bars.

    Declaration

    Swift

    @MainActor
public var barCount: Int { get set }

  • Number of beats in a measure.

    Declaration

    Swift

    @MainActor
public var beatCount: Int { get set }

  • Number of grid subdivisions per beat, used for drawing the small snap ticks within a beat. Defaults 4.

    Declaration

    Swift

    @MainActor
public var snapResolution: Int { get set }

  • Property to show bar numbers. Defaults true.

    Declaration

    Swift

    @MainActor
public var showsBarNumbers: Bool { get set }

  • The x-range (in this view’s own coordinate space) of bars to realize layers for. Bars outside it are freed into a reuse pool instead of laid out, so the number of live MIDITimeTableMeasureLayers tracks what’s on screen rather than the whole timeline. The owning MIDITimeTableView keeps this in sync with the visible viewport (plus a small overscan margin) on every layout pass, including scroll. Defaults to a large placeholder so a view used standalone, before anything sets a real value, still shows its bars.

    Declaration

    Swift

    @MainActor
public var virtualizationRect: CGRect

  • Forces every bar layer to be rebuilt from scratch on the next layout pass. You shouldn’t normally need this — barCount/beatCount/snapResolution/showsBarNumbers already trigger a refresh when they actually change — but it’s kept as a manual escape hatch.

    Declaration

    Swift

    @MainActor
public func update()

  • Undocumented

    Declaration

    Swift

    @MainActor
open override func layoutSubviews()
