Instance Method

userSpaceScaleFactor

Returns the scale factor applied to the window.

Declaration

- (CGFloat)userSpaceScaleFactor;

Return Value

The scale factor applied to the window.

Discussion

Clients can multiply view coordinates by the returned scale factor to get a set of new coordinates that are scaled to the resolution of the target screen. For example, if the scale factor is 1.25 and the view frame size is 80 x 80, the actual size of the view frame is 100 x 100 pixels on the target screen.
