Question

I have profiled one of my apps using Allocations, and find that whenever I call a particular method my amount of “Live Bytes” increases by 300 KB. I have no idea what could be causing this.

The following line of code is the culprit:

CNTile *newTile = [self getTileAtPosition:3];

The associated method reads like this:

- (CNTile *)getTileAtPosition:(int)pos
{
    CNTile *tileToReturn;

    for (int x = 0; x < [row count]; x++)
    {
        for (int y = 0; y < [col count]; y++)
        {
            The code here generates four CGPoints and a CGMutablePathRef,
            then uses CGPathContainsPoint to determine which CNTile to return.
        }
    }

    return tileToReturn;
}

I should mention that my CNTile class contains only a UIView and UIImageView, as well as a few simple variables (such as ints and BOOLs).

Any help would be greatly appreciated!

How do you create CGMutablePathRef? With CGPathCreateMutable? If yes, make sure you use CGPathRelease to release it:

CGMutablePathRef thePath = CGPathCreateMutable();
...
CGPathRelease(thePath);
