MTAnimatedLabel requires the following frameworks:
CoreText QuartzCore UIKit Foundation CoreGraphics
A UILabel subclass that uses CATextLayer & CAGradientLayer to accomplish an iPhone lock screen like animation.
Just as you would use any other UILabel, either from a nib or in code.
/*Example*/ MTAnimatedLabel *label = [[MTAnimatedLabel alloc] initWithFrome:CGRectMake(0,0,100,35)]; label.text = @"slide to unlock"; [self.view addSubview:label]; [label startAnimating]; //begins animation //call animate again to stop the animation [label stopAnimating];
It's is also possible to change the gradient tint, animation duration, and gradient width.
MTAnimatedLabel uses a CATextLayer to mask a CAGradientLayer which requires off screen rendering. Due to this MTAnimatedLabel should only be used when animation is required.
MTAnimatedLabel does not currently respect the following UILabel properties:
1. lineBreakMode 2. shadows on text are not currently working 3. baselineAdjustment 4. highlighting 5. autosizeTextToFit 6. numberOfLines
If you feel like jumping in on some of these please feel free!
