Question

I would like to draw a glow-ish border around a UIView which is roughly 5px from the actual UIView itself.

Please could you tell me how I could achieve this?

Answer 1

Probably the easiest way is to create a shadow, but use a light color instead of a dark one. Shadow details can be found here: How do I draw a shadow under a UIView? and here.

Something like this should get the ball rolling:

- (void)drawRect:(CGRect)rect
{
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSaveGState(context);
    CGContextSetShadowWithColor(context, CGSizeMake(0, 0), 10,
                                [UIColor whiteColor].CGColor);
    [super drawRect:rect];
    CGContextRestoreGState(context);
}

Update: I just tried this out. You will have to use this code on the superview of the glowing view for it to work properly.
