objective c - Need help wih references - ARC + Cocos 2d -
arc kicking arc
i installed cocos 2d , unhappy seeing wanted use arc. having issue can't quite seem figure out.
instruments saying have 5 references graphicsmanager object, yet can conclude 4 of them. need create , release many of these.
class "rowmanager" (cclayer) calls class "graphicsmanager" (ccnode) make these objects. rowmanager calls methods move objects via selector: [self schedule:@selector(row:) interval:.01]
finally, when object arrives @ point, method "row1finished" called creates 1 more reference object before calling object (die) remove it's own children.
i can 3 animations stop, object detach rowmanager , disappear, yet dealloc method still not call itself. doing wrong?
to convert non-arc cocos2d template followed instructions here:

you can use (__bridge id) exclude arc, need exclude & use manual retain-release.
