detect a collision don't work

Hi,

i make that :
collision beetween sprite A and sprite B
>add to counter
>destroy sprite B

sprite A and sprite B is on the same layer. I have 4 layers.

In the mmf runtime, it works. When i export on android, it works too. I export to IOS and and it doesn't work !!!!
I try to change collision by overlapping, same result !!!

please help !

This was not a collide problem but a property problem. It seems that the property destroy objet is too far work in IOS when your objet is just outside the frame ! Even if it is 10 px ! :(
So carefull to this ! ;)
