Enumeration 列挙

TimelineView.Context.Cadence

A rate at which timeline views can receive updates.

Declaration 宣言 

enum Cadence

Overview 概要

Use the cadence presented to content in a TimelineView to hide information that updates faster than the view’s current update rate. For example, you could hide the millisecond component of a digital timer when the cadence is TimelineView.Context.Cadence.seconds or TimelineView.Context.Cadence.minutes.

Because this enumeration conforms to the Comparable protocol, you can compare cadences with relational operators. Slower cadences have higher values, so you could perform the check described above with the following comparison:


let hideMilliseconds = cadence > .live

Getting Cadences

case live
Updates the view continuously.
case seconds
Updates the view approximately once per second.
case minutes
Updates the view approximately once per minute.

Comparing Cadences

static func ... (Self) -> PartialRangeFrom<Self>
Returns a partial range extending upward from a lower bound. 下側の境界から上方に拡張している部分的な範囲を返します。
static func ... (Self) -> PartialRangeThrough<Self>
Returns a partial range up to, and including, its upper bound. それの上側の境界までの、そしてそれを含む部分的な範囲を返します。
static func ... (Self, Self) -> ClosedRange<Self>
Returns a closed range that contains both of its bounds. それの境界の両方を含む完結範囲を返します。
static func ..< (Self) -> PartialRangeUpTo<Self>
Returns a partial range up to, but not including, its upper bound. それの上側の境界までの、しかしそれを含んでいない、部分的な範囲を返します。
static func ..< (Self, Self) -> Range<Self>
Returns a half-open range that contains its lower bound but not its upper bound. それの下側の境界は含むがそれの上側の境界はそうしない半開範囲を返します。
static func < (TimelineView<Schedule, Content>.Context.Cadence, TimelineView<Schedule, Content>.Context.Cadence) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument. 最初の引数の値が２番目の引数のそれより少ないかどうかを指し示しているブール値を返します。
static func > (Self, Self) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument. 最初の引数の値が２番目の引数のそれより大きいかどうかを指し示すブール値を返します。
static func <= (Self, Self) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument. 最初の引数の値が２番目の引数のそれより少ないまたは等しいかどうかを指し示すブール値を返します。
static func >= (Self, Self) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument. 最初の引数の値が２番目の引数のそれより大きいまたは等しいかどうかを指し示すブール値を返します。
static func == (TimelineView<Schedule, Content>.Context.Cadence, TimelineView<Schedule, Content>.Context.Cadence) -> Bool
Returns a Boolean value indicating whether two values are equal. ２つの値が等しいかどうかを指し示すブール値を返します。
static func != (Self, Self) -> Bool
func hash(into: inout Hasher)
Hashes the essential components of this value by feeding them into the given hasher. この値の必須の構成要素を、それらをこの与えられたハーシャーに供給する事によってハッシュ化します。
var hashValue: Int
The hash value. ハッシュ値。
