Simple case in -updateVisibleGridCellsNow always not called (“Comparison is always false”)

[coreyfloyd]

currentVisibleIndices is created from the range: _visibleIndices. Then immediately compared. It appears as though the comparison should be between newVisibleIndices and _visibleIndices.

Still working through the code, so don't want to make any changes I don't understand yet.

Class AQGridview.m
method: - (void) updateVisibleGridCellsNow;

starting about line: 1563

NSIndexSet * newVisibleIndices = [_gridData indicesOfCellsInRect: [self gridViewVisibleBounds]];

    BOOL enableAnim = [UIView areAnimationsEnabled];
    [UIView setAnimationsEnabled: NO];

    @try
    {
        // a couple of simple tests
        // TODO: if we replace _visibleIndices with an index set, this comparison will have to change
        if ( ([_visibleCells count] != [newVisibleIndices count]) ||
            ([newVisibleIndices countOfIndexesInRange: _visibleIndices] != _visibleIndices.length) )
        {
                        // something has changed. Compute intersections and remove/add cells as required
            NSIndexSet * currentVisibleIndices = [NSIndexSet indexSetWithIndexesInRange: _visibleIndices];

            // index sets for removed and inserted items
            NSMutableIndexSet * removedIndices = nil, * insertedIndices = nil;

            // handle the simple case first
            // TODO: if we replace _visibleIndices with an index set, this comparison will have to change
            if ( [currentVisibleIndices intersectsIndexesInRange: _visibleIndices] == NO )
            {
                removedIndices = [[currentVisibleIndices mutableCopy] autorelease];
                insertedIndices = [[newVisibleIndices mutableCopy] autorelease];
            }
