A set of animatable weight values that collectively represent the blending amounts for all the blend shapes' blend targets.

Members (7)

get · iOS 18.0+

startIndex

TypeScript

get startIndex(): number

Swift declaration

var startIndex: BlendShapeWeights.Index { get }

An index to the first weight in the collection. For more on the sequence's beginning index, see <doc://com.apple.documentation/documentation/swift/array/1541237-startindex>.

method · iOS 18.0+

index

TypeScript

indexAfter(i: number): number

Swift declaration

func index(after i: BlendShapeWeights.Index) -> BlendShapeWeights.Index

Returns the position in the sequence of the weight that follows the given position. For more on calculating indices, see <doc://com.apple.documentation/documentation/swift/array/1787306-index>.

method · iOS 18.0+

index

TypeScript

indexBefore(i: number): number

Swift declaration

func index(before i: BlendShapeWeights.Index) -> BlendShapeWeights.Index

Returns the position in the sequence of the weight that preceeds the given position. For more on calculating indices, see <doc://com.apple.documentation/documentation/swift/array/1782301-index>.

get · iOS 18.0+

endIndex

TypeScript

get endIndex(): number

Swift declaration

var endIndex: BlendShapeWeights.Index { get }

An index to the last weight in the collection. For more more on the sequence's final index, see <doc://com.apple.documentation/documentation/swift/array/1539310-endindex>.

init · iOS 18.0+

init

TypeScript

static init(): BlendShapeWeights

Swift declaration

init()

Initializes a collection of animatable weights for a blend shape.

init · iOS 18.0+

init

TypeScript

static init7649(weights: Array<number>): BlendShapeWeights

Swift declaration

init<S>(_ weights: S) where S : Sequence, S.Element == Float

Initializes a collection of weights for a single blend shape. - Parameters: - weights: An array of float weights for the blend shape.

subscript · iOS 18.0+

subscript

TypeScript

subscript(index: number): number

Swift declaration

subscript(index: BlendShapeWeights.Index) -> Float { get set }

Accesses a single weight in the collection at the given index. For more on accessing elements by index, see <doc://com.apple.documentation/documentation/swift/array/1540606-subscript>.
