Question

I am getting up to speed on using ARC for my iOS app development. Occasionally a plain ole c-array of plain old c-structs is all I need to get the job done. Prior to ARC I would just add free() to my dealloc method. With ARC there is nolonger any need for dealloc. Is there an ARC directive I can add to tell the compiler to handle free-ing my c-array(s)?

Per Tom’s answer here is the dealloc method

// EIVertex
struct EIVertex {
    GLKVector3 p;
    GLKVector3 n;
    GLKVector3 barycentric;
    GLKVector2 st;
};

typedef struct EIVertex EIVertex;

// ivar declaration
EIVertex *_vertices;

// malloc an array of EIVertex
_vertices = (EIVertex *)malloc([_triangles count] * sizeof(EIVertex));

// Note lack of [super dealloc]
- (void)dealloc{

    // ARC will not handle mem. management for plain ole c arrays.
    free(_vertices);
}

You can still overload dealloc. The only thing is you can not explicitly call it. So write dealloc as you used to, but dont call [super dealloc] in it.
