Instance Method

zoom(to:animated:)

Zooms to a specific area of the content so that it is visible in the receiver.

Declaration

func zoom(to rect: CGRect, animated: Bool)

Parameters

rect

A rectangle defining an area of the content view. The rectangle should be in the coordinate space of the view returned by viewForZooming(in:).

animated

true if the scrolling should be animated, false if it should be immediate.

Discussion

This method zooms so that the content view becomes the area defined by rect, adjusting the zoomScale as necessary.
