I used to only test my game in android and it performs well, but there is a problem when I start testing it on iphone4.
That is, Sprites looks broken when I move them with touch events.
In my game, I have 5\~6 sprites with different z-order in a layer, and they will be moved to different locations by user’s touch events.
However, when I play it in iphone4, some sprites with higher z-order will be “partially” covered by sprites with lower z-order, so it looks broken….
ps: fps shows from 50\~60, so I don’t think that I put too many sprites on it and it performs perfectly in android…QQ
Does anyone know how to solve it? or what causes this problem?
