Instance Method


Sends a pinching gesture with two touches.


- (void)pinchWithScale:(CGFloat)scale velocity:(CGFloat)velocity;



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.


The velocity of the pinch in scale factor per second.


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.
