rect = CGRectMake(rect.origin.x + 15, rect.origin.y + 15, rect.size.width + 15, rect.size.height + 15);

Here, I’m using 15 as the average glowSize.

Thanks so much for this. For anyone else reading this – a gotcha that tripped me up was forgetting to change the class of the UILabel in Interface Builder to RRSGlowLabel ;)

I am having one issue with this though, being that the labels I am working with need to be aligned to the left and the glow is being cut off where the UILabel ends.

Here is an image of the effect from your sample code. The effect is even worse when the Text itself starts there, such as with a T or D…

Do you have any idea how to get around this? The closest thing I came across in the documentation was to subclass – (void)drawTextInRect:(CGRect)rect which I can see you are already doing.

I did come across the following sample code, but have been unable to fine a suitable place to fit this into my code or yours.

CGRect frame = self.frame;
frame.size.width += 20; //l + r padding
self.frame = frame;

Ideally, I’m looking for something to the effects of padding the UILabel so that there is enough room for the glow. This would need to carry over when the frame of the label changes (for orientation changes), or be something that could be called again at the time of the orientation change.

Having something where the glow permeates beyond the edge of the UILabel would also work fine!

Any ideas?
