I think you probably want to wrap your loop in another loop, to get what I'm going to call a 2D loop:

for (int row = 0; row < num_rows; row++) {
   for (int col = 0; col < num_cols; col++) {
        // code before
        zenButton2.frame = CGRectMake(origin x dependent on col,
                                      origin y dependent on row,
                                      width,
                                      height);
        // code after
   }
}

Where the x and y of the CGRectMake() are multiples of the width and height of your image times the row and column respectively. Hope that makes sense.
