The key is to use UIImpactFeedbackGenerator
.
My demo:
import objc_util, time
feedback = objc_util.ObjCClass('UIImpactFeedbackGenerator').new()
feedback.initWithStyle(0)
for I in range(0, 9):
feedback.impactOccurred()
time.sleep(0.1)
This demo will generate "impact feedback" with rhythm.
Another way is to use AudioToolbox.h
C API. I learned from this topic, but I found another system sound IDs to perform different intensities.
AudioServicesPlaySystemSound(1519);
AudioServicesPlaySystemSound(1520);
AudioServicesPlaySystemSound(1521);
Where 1519
and 1520
are the same feedbacks when you use 3D touch, 1521
is a 3 combo light vibrate.
