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 isn’t guaranteed. Some values may not be possible based on the size of the element’s frame, and they result in test failures.
