FIX for indexOfObject: returns max int for tapped card

[danipralea]

Hi, you might want to replace the code for - (void)handleTap:(UIGestureRecognizer *)gestureRecognizer

with

    if ([self.gridViewDelegate respondsToSelector:@selector(gridView:didSelectCell:index:)]) {
        CGRect viewFrame = gestureRecognizer.view.frame;
        NSInteger index2 = [self.gridRects indexOfObjectPassingTest:^BOOL(id obj, NSUInteger idx, BOOL *stop) {
            NSValue \* value = (NSValue *)obj;
            CGRect rect = [value CGRectValue];
            CGFloat lowX = viewFrame.origin.x - 0.1;
            CGFloat highX = viewFrame.origin.x + 0.1;

    CGFloat lowY = viewFrame.origin.y - 0.1;
    CGFloat highY = viewFrame.origin.y + 0.1;

    CGFloat lowWidth = viewFrame.size.width - 0.1;
    CGFloat highWidth = viewFrame.size.width + 0.1;

    CGFloat lowHeight = viewFrame.size.height - 0.1;
    CGFloat highHeight = viewFrame.size.height + 0.1;

    BOOL xOK = rect.origin.x >= lowX && rect.origin.x <= highX;
    BOOL yOK = rect.origin.y >= lowY && rect.origin.y <= highY;
    BOOL widthOK = rect.size.width >= lowWidth && rect.size.width <= highWidth;
    BOOL heightOK = rect.size.height >= lowHeight && rect.size.height <= highHeight;

    return (xOK && yOK && widthOK && heightOK);
}];
[self.gridViewDelegate gridView:self didSelectCell:gestureRecognizer.view index:index2];

}

}```

because there are cases when values for rectangles do no match (because of the floating point) the frame of the tapped view.
Example : you have in your array one rect with origin.x = 56.666444, but you tapped view has origin.x = 56.666452, so it will give you out of bounds index for that card, resulting in crashing the application.
That's why you don't search a rectangle in an array of rectangles.
