Question

Hi Im confusing how to release already aclloc class which dosen’t store pointer from the header file. After the loop I lost my pointer to classes since it has all same instance name.

for(i=0;i<20;i++){
  MyClass *class = [[MyClass init]alloc];
   class.count = i;
  [classArray addObject:class];  
  [self addToScene:class];

}

I understand basic concept of memory alloc and retain but since I’m using cocos2d to programe, I’m not sure about the cause of the error is from Object-c or cocos2d. so I want to just make a clear idea about the dealing memory in object-c. help me:-)

Præ-scriptum: that alloc and init calls should be exchanged (allocate first, only then initialize).

You have to release them inside the loop – adding them to the array retains them.

for(i = 0;i < 20; i++) {
    MyClass *obj = [[MyClass alloc] init];
    obj.count = i;
    [classArray addObject:obj];
    [obj addToScene:obj];
    [obj release];
}
