Why does Xcode flag the indicated line with a warning? Is this saying the compiler has no introspection into the CPTImageSlices struct since it could have any combination of initialized/uninitialized elements?

    typedef struct _CPTImageSlices {

        CGImageRef slice[9];

}

    CPTImageSlices;

@property (nonatomic, readwrite, assign) CPTImageSlices slices;

    -(void)setEdgeInsets:(CPTEdgeInsets)newEdgeInsets

{

        if ( !CPTEdgeInsetsEqualToEdgeInsets(edgeInsets, newEdgeInsets) ) {

            edgeInsets = newEdgeInsets;

            CPTImageSlices imageSlices;

            for ( NSUInteger i = 0; i < 9; i++ ) {

                imageSlices.slice[i] = NULL;

}

            self.slices = imageSlices;  //<-- warning here

}

}

    -(void)setSlices:(CPTImageSlices)newSlices
    {
        for ( NSUInteger i = 0; i < 9; i++ ) {
            CGImageRelease(slices.slice[i]);
            
            slices.slice[i] = CGImageRetain(newSlices.slice[i]);
        }
    }
