In my IPhone application, I want the text in UILabel to glow for a second, then fade for a sec;. Also i want to repeat this cycle for say 3 or 4 times.

Is this possible?

As of 3.2 you there is direct support for shadows in the SDK.

label.layer.shadowColor = [label.textColor CGColor];
label.layer.shadowOffset = CGSizeMake(0.0, 0.0);

Play with the parameters:

label.layer.shadowRadius = 3.0;
label.layer.shadowOpacity = 0.5;

And to avoid shadow being clipped by the label bouds:

label.layer.masksToBounds = NO;

Don't forget to

#include <Quartzcore/Quartzcore.h>

and link against the QuartzCore or CoreGraphics frameworks (thanks to commenters for pointing this out).

IPhone Text Glow Effect, Not "blinking" but if you use the shadow effect and set it's offset to zero, altering the size of the shadow now makes it look like it's glowing. You can also play with the text shadow (change the colour and alpha) and see if you can come up with a decent glow. The easiest way is probably to make a transparent glow-outline image in photoshop and place it behind your text, and then do like mahboudz suggests fade the image in and out using coreanimation. share | improve this answer

I've posted some sample code which subclasses UILabel and enables you to apply glow and soft shadows to text.

Is it possible to make text glow?, Make your iMessages even more expressive with Memoji sticker effects, bubble effects, full-screen animations, camera effects, and more. Create glowing text effect on iOS. We're currently building an iPhone app and would like the text to have a glowing effect to fit in with the realistic UI design. Here is what we're trying to achieve. We are struggling to create the inner glow effect at the moment so any help would be appreciated.

Yes. Use beginAnimation...commitAnimation, and use the alpha value to brighten or dim the ULabel. Make sure that the default value of the UILabel's alpha starts at 0.85 and brightens to 1.0 and then dims to 0.75, and when all is done, you go back to 0.85.

There are other ways to do it such as having another view on top of the label that is gray or black and you use the same begin...commitAnimation to change the alpha on that from 0 to 0.20 or so.

There are many ways to do this, with varying quality. One way would be to subclass UILabel, and implement some kind of gradient effect in coregraphics in the drawRect method.

You can also play with the text shadow (change the colour and alpha) and see if you can come up with a decent glow.

For both bubble and screen effects, you can manually launch them by long-pressing the send button (upward arrow). At the top of the "Send with effect" screen, you can toggle between bubble and screen. Here, you can send your message with the bubble effects (as of iOS 13: slam, loud, gentle, and invisible ink) or screen effects (the four above

- (UILabel *) setUpGlowLabelWithFrame: (CGRect) frame fontSize: (int)fontSize {

    label.numberOfLines = 2;

I get the glow effect when using this.

Hope it helps.

Happy coding :)

Comments
  • nice question. I want to do the exact thing.
  • You should accept @andrewgleave's answer, as it worked great!
  • You need to import <Quartzcore/Quartzcore.h>
  • have Quartzcore and compiled successfully, but don't see any effect at all?
  • You have to link QuartzCore.framework or CoreGraphics.framework (the latter contains the former). Again, thanks, I'm updating the answer
  • I was able to see the glow after changing the shadow radius from 20.0 to a smaller number 1-5, it's much harder to see that this code works unless making that change. Not to say that a shadow radius of 20 isn't a good choice, but it's just very very faint.
  • Read the question please
  • He is answering the animation part alone, so this answer is ok.
