This library allows you to provide labels with glowing effect easily.

There are some other tutorials or libraries to support glowing effect. But most of them support only outer glow simply using shadow features of CoreGraphics. Sometime people may feel it's cheap. To make it not cheap, the most important essence is inner glow

See following images, these two use only outer glow.

These are not so bad, but somehow cheap. Then, see following image which is with inner glow.

Perfect!

If you use CocoaPods, add following line into your Podfile

pod 'FBGlowLabel', :git => 'https://github.com/lyokato/FBGlowLabel.git'

or directly git clone or download from this page.

Most of the usage is same as UILabel. And you can set just 4 more properties. too simple.

• glowColor
• glowSize
• innerGlowColor
• innerGlowSize

#import <FBGlowLabel/FBGlowLabel.h>

- (void)setupLabel
{
  CGRect frame = CGRectMake(10, 100, 300, 100);
  FBGlowLabel *v = [[FBGlowLabel alloc] initWithFrame:frame];
  v.text = kInitialText;
  v.textAlignment = NSTextAlignmentCenter;
  v.clipsToBounds = YES;
  v.backgroundColor = [UIColor clearColor];
  v.font = [UIFont fontWithName:@"Helvetica-Bold" size:40];
  v.alpha = 1.0;
  v.textColor = UIColor.whiteColor;

  v.glowSize = 20;
  v.glowColor = UIColor.greenColor;

  v.innerGlowSize = 4;
  v.innerGlowColor = UIColor.greenColor;

  self.label = v;
  [self.view addSubview:v];
}
