Finds a member of a transform group by its name.

Declaration

func SecTransformFindByName(_ transform: SecGroupTransform, _ name: CFString) -> SecTransform?

  • transform:

    The transform group to be searched.

  • name:

    The name of the transform to be found.

Return Value

The transform group member, or NULL if the member was not found.

Discussion

When a transform instance is created you give it a unique name. This name can be used to find that instance in a group. While it is possible to use the SecTransformSetAttribute(_:_:_:_:) function to change a transform’s name after creating it, this is not recommended because doing so causes the SecTransformFindByName(_:_:) function to misbehave.
