Draw filled dynamic polygon in Cocos2D, iOS

How can i draw polygon with points read from NSMutableArray object in cocos2D framework?

I am able to draw polygon using this function: filled antialiased poly cocos2d

The problem is becouse points argument *(CGPoint poli) must be static object.

Any ideas or suggestions?

What is type of NSMutableArray objects? You need to extract raw data of points and set it as poli argument. If it's NSValue with CGPoint then:

NSMutableArray* yourPointsArray;
...
CGPoint* poli = malloc (sizeof (CGPoint) * [yourPointsArray count]);
for (uint i=0; i<[yourPointsArray count]; i++)
{
    poli[i] = [[yourPointsArray objectAtIndex: i] CGPointValue];
}
ccFillPoly (poli, [yourPointsArray count], YES);
free (poly);
