如何在iOS中的文本上创建“浮雕”效果？

Question

I wanted to create " Embossed " text effect on a text in a UILabel. I am not able to choose a right option. Please guide me on how to implement this with the right available options. Do i need to use CoreGraphics or CoreText or Customized UILabel ?. I just want the way how numbers appear on a Credit Card.

Answer 1

Try this,

[label setShadowColor:[UIColor darkGrayColor]];
[label setShadowOffset:CGSizeMake(0, -1)];

You can tweak this to get the desired effect.

Answer 2

UILabel's shadowColor and shadowOffset offer a limited customisation. You could also override UILabel's drawRect:

-(void)drawTextInRect:(CGRect)rect
{
    CGContextRef ref = UIGraphicsGetCurrentContext();
    CGContextSetShadowWithColor(ref, CGSizeMake(0.0, 2.0), 3.0, [UIColor blackColor].CGColor);
    [super drawTextInRect:rect];
}
