EventListenerTouchAllAtOnce incorrect

[NgVThangBz]

I use EventListenerTouchAllAtOnce to listen for layer touch events,
but it seems touches always = 1, how do I know if I'm touching the screen with 2 fingers?

Please have a look on cpp-test. There is a multitouch example

[NgVThangBz]

Yes, I looked at it, and I don't see the difference between the two codes

[aismann]

And the example works?
Please have a closer look or a comparing tool

I try to help you. Not more. I dont have an ios system. Im out. Sorry no longer time for you.
Maybe you can add this source snipper and not others PLEASE:
AXLOG("%d",touches.size()); (no "if" !!!)

and what is the result?

Of course they will log 1 <<< has your system multitouch display?
If Yes: Maybe a bug on axmol/cocos4.0

You can look at my code again, I log the size of touches ( unsigned long s = touches.size();), and it's always equal to 1,
and of course my screen has multitouch, i use ipad th7, and the code i used on cocos2dx 3.17 and it works fine

[aismann]

What is the size result on cocos2dx?

[NgVThangBz]

2, Of course ( number of touch),
and affter debug in EAGLView-ios.mm in onTouch ( image bellow)
touches size is 1, but (UIEvent*)event in allTouches UITouch* touch have size 2
so please check it again.i think it wrong in ios

[aismann]

Can you make an Issue with all useful information?
Or better an PR with the fix?
If done please set the answer point too please.

[aismann]

It works on Windows. iOS dont have it

Did you enable multiple touch?
[__glView setMultipleTouchEnabled:YES];

[NgVThangBz]

it seems this is the cause
