iphone - Do tagged images occupy memory/locations? -

i wondering if tagged images can occupy memory/locations (i'm not sure call them call them memory/locations)...

the code below used find matches , removes them view when 3 or more in row/column. thing though seems if statements works once. once have been used stop finding matches.

is there way of "releasing" occupied if statements or there way of doing this?

for( int y=0; y<height-2; y++ ){ for( int x=0; x<width-2; x++ ){      //don't match empty squares     if(grid[x][y] == nil){         continue;         nslog(@"continue");     }      if(x >= 2 && x <= width -2  && y >= 2 && y <= height - 2) {          //check right         if(grid[x+1][y].tag == grid[x][y].tag && grid[x+2][y].tag == grid[x][y].tag) {              nslog(@"to right");              grid[x][y].alpha = 0;             grid[x+1][y].alpha = 0;             grid[x+2][y].alpha = 0;               nslog(@"match right grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match right grid[x+1][y].tag %d",grid[x+1][y].tag);             nslog(@"match right grid[x+2][y].tag %d",grid[x+2][y].tag);          }          //check left         else if (grid[x-1][y].tag == grid[x][y].tag && grid[x-2][y].tag == grid[x][y].tag){              nslog(@" left");              grid[x][y].alpha = 0;             grid[x+1][y].alpha = 0;             grid[x+2][y].alpha = 0;              nslog(@"match left grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match left grid[x-1][y].tag %d",grid[x-1][y].tag);             nslog(@"match left grid[x-2][y].tag %d",grid[x-2][y].tag);          }          //check         else if(grid[x][y-1].tag == grid[x][y].tag && grid[x][y-2].tag == grid[x][y].tag){              nslog(@"up");                 grid[x][y].alpha = 0;             grid[x][y-1].alpha = 0;             grid[x][y-2].alpha = 0;                       nslog(@"match grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match grid[x][y-1].tag %d",grid[x][y-1].tag);             nslog(@"match grid[x][y-2].tag %d",grid[x][y-2].tag);          }          //check down         else if(grid[x][y+1].tag == grid[x][y].tag && grid[x][y+2].tag == grid[x][y].tag){              nslog(@"down");              grid[x][y].alpha = 0;             grid[x][y+1].alpha = 0;             grid[x][y+2].alpha = 0;              nslog(@"match down grid[x][y].tag %d",grid[x][y].tag);             nslog(@"match down grid[x][y+1].tag %d",grid[x][y+1].tag);             nslog(@"match down grid[x][y+2].tag %d",grid[x][y+2].tag);          }      else{         gamepaused = no;     } } 

}

no, don't take memory. assigned identified uniquely in parent.
