IOS adds bottom border to UILabel with shadow

Question

Can I learn how to add a lower border to a UILable with only a shadow? There is no upper, left, right border.

this does not work. Here is the code I tried, but it does not work.

 CALayer* layer = [titleLabel layer]; layer.frame = CGRectMake(-1, -1, titleLabel.frame.size.width, 1.0f); layer.borderWidth=1; [layer setBorderWidth:2.0f]; [layer setBorderColor:[UIColor blackColor].CGColor]; [layer setShadowOffset:CGSizeMake(-3.0, 3.0)]; [layer setShadowRadius:5.0]; [layer setShadowOpacity:5.0]; 

Answer 1

Test this way:

 UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 50)]; [lbl setText:@"Testo di prova..."]; [lbl setBackgroundColor:[UIColor clearColor]]; [[self view] addSubview:lbl]; [lbl sizeToFit]; CALayer* layer = [lbl layer]; CALayer *bottomBorder = [CALayer layer]; bottomBorder.borderColor = [UIColor darkGrayColor].CGColor; bottomBorder.borderWidth = 1; bottomBorder.frame = CGRectMake(-1, layer.frame.size.height-1, layer.frame.size.width, 1); [bottomBorder setBorderColor:[UIColor blackColor].CGColor]; [layer addSublayer:bottomBorder]; 

Hope this helps you.

Just send this answer for reference, as the user has already received the answer. Try this code in Swift and let me know how this happens.

 func buttomBorder(label: UILabel) -> UILabel { // For Buttom Border let frame = label.frame let bottomLayer = CALayer() bottomLayer.frame = CGRect(x: 0, y: frame.height - 1, width: frame.width - 2, height: 1) bottomLayer.backgroundColor = UIColor.lightGray.cgColor label.layer.addSublayer(bottomLayer) //For Shadow label.layer.shadowColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.25).CGColor label.layer.shadowOffset = CGSizeMake(0.0, 2.0) label.layer.shadowOpacity = 1.0 label.layer.shadowRadius = 0.0 label.layer.masksToBounds = false label.layer.cornerRadius = 4.0 return label } 

Function call:

  labelName = buttomBoder(label: labelName)
