Instance Method

pinch(withScale:velocity:)

Sends a pinching gesture with two touches.

Declaration

func pinch(withScale scale: CGFloat, velocity: CGFloat)

Parameters

scale

The scale of the pinch gesture. Use a scale between 0 and 1 to "pinch close" or zoom out and a scale greater than 1 to "pinch open" or zoom in.

velocity

The velocity of the pinch in scale factor per second.

Discussion

The system makes a best effort to synthesize the requested scale and velocity, but absolute accuracy is not guaranteed. Some values may not be possible based on the size of the element's frame; these will result in test failures.
