ios - Touch events responding is delayed when 3D touch is ON -
recently test app on iphone 6s , iphone 6sp 3d touch on. notice 3 strange things:
- when finger touches on left edge of screen, app responds touch events after 1s delay.
- when touch on left edge of screen , push force, 3d touch task switcher shows.
- but if tap left edge of screen, app can respond touch events immediately.
i test many other 3rd apps , system apps (notes, contacts) phenomenon exists 3d touch on. when turn 3d touch off, app responds touch events usual.
on other hand, system keyboard responds touch events whether 3d touch on or off.
i guess it’s because touch events responding conflicts 3d touch task switcher. have tried many 3d touch apis have no effects.
does have idea? thanks!
