Memory Leaks when calling some CTFunctions in iPhone

Question

I write a function to calculate the end index of attributtedString in a rect,

But it seems some memory leak, Please help me to fix it.

CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString((CFAttributedStringRef)attributtedString);

CGMutablePathRef path = CGPathCreateMutable();
CGPathAddRect(path, NULL, rect);

CTFrameRef frame = CTFramesetterCreateFrame(framesetter, CFRangeMake(currentIndex, 0), path, NULL);

CFRange frameRange = CTFrameGetVisibleStringRange(frame);
endIndex += frameRange.length;

CFRelease(frame);
CFRelease(path);
CFRelease(framesetter);

thanks in advance.

There is no memory leak in the above example. As far as we can see you are releasing everything properly.
