concatenate(_:)

Appends the given transform to the context’s existing transform.

Declaration 宣言 

mutating func concatenate(_ matrix: CGAffineTransform)

Parameters パラメータ

matrix

A transform to append to the existing transform.

Discussion 議論

Calling this method is equivalent to updating the context’s transform directly using the matrix parameter:


transform = matrix.concatenating(transform)
