Adding glow effect to UIButton - iOS

I have an UIButton which is a logo. This logo button will glow on forever but will stop glowing on touch.It is like a glowing animation.

Is there any suggestions?

  Undefined symbols for architecture i386:
 "_OBJC_CLASS_$_CABasicAnimation", referenced from:
 objc-class-ref in UIView+Glow.o
 "_OBJC_CLASS_$_CAMediaTimingFunction", referenced from:
  objc-class-ref in UIView+Glow.o
  "_kCAMediaTimingFunctionEaseInEaseOut", referenced from:
  -[UIView(Glow) startGlowing] in UIView+Glow.o
   ld: symbol(s) not found for architecture i386
   clang: error: linker command failed with exit code 1 (use -v to see invocation)
Solution

  • I suggest you use the Glow Category of UIView made by secret lab.

    Example is available here
