Question

I use QuartzCore to set UILabel shadows in UITableViewCell:

cell.textLabel.layer.shadowColor = [[UIColor orange] CGColor];
cell.textLabel.layer.shadowOffset = CGSizeMake(0.0, 1.0);
cell.textLabel.layer.shadowRadius = 0.0;
cell.textLabel.layer.masksToBounds = NO;

But because of it slow performance, I have to implement -(void)drawRect:(CGRect)rect method.
Recently I found out that shadow for UILabel can be set with it properties:

cell.textLabel.shadowColor = [UIColor orangeColor];
cell.textLabel.shadowOffset = CGSizeMake(0.0, 1.0);

Now I want delete drawRect: implementation and just set shadows through properties.

QuartzCore CALayer shadowRadius default value is 3.0.
Though UILabel has not such property, is it mean that shadow radius equauls 0.0?

Answer 1

The documentation for UILabel says:

Text shadows are drawn with the specified offset and color and no blurring.

So, yes, the shadow radius is 0.
