ZCAnimatedLabel is available via CocoaPods. If you don't need all the effect subclasses, simply drag ZCAnimatedLabel.(h|m), ZCCoreTextLayout.(h|m) and ZCEasingUtil.(h|m) into your project and start customizing your own.

ZCAnimatedLabel has two modes: non-layer based and layer based. In the first mode, ZCAnimatedLabel is a flat UIView, every stage of animation is drawn using Core Graphics, you can customize redraw area for your animation for better performance. Following methods can be overriden:

• - (void) textBlockAttributesInit: (ZCTextBlock *) textBlock;
• - (void) appearStateDrawingForRect: (CGRect) rect textBlock: (ZCTextBlock *) textBlock;
• - (void) disappearStateDrawingForRect: (CGRect) rect textBlock: (ZCTextBlock *) textBlock;
• - (CGRect) redrawAreaForRect: (CGRect) rect textBlock: (ZCTextBlock *) textBlock;

Second option is layer based, where each text block is a simple CALayer, 3D tranform is possible in this mode by setting layer's transform property, if redraw area is bigger and not too many text blocks, this can achive a performance gain. Set self.layerBased to YES and override following methods for customization:

• - (void) textBlockAttributesInit: (ZCTextBlock *) textBlock;
• - (void) appearStateLayerChangesForTextBlock: (ZCTextBlock *) textBlock;
• - (void) disappearLayerStateChangesForTextBlock: (ZCTextBlock *) textBlock;

• Merge CALayers no longer animating into a single backing store and reuse CALayer for animating layers. (Even better performance for layerBased implementation)
• More Effects, possily glyph related ones
• Use core animation emmiter

• LTMorhpingLabel for heavy inspiration. If you like ZCAnimatedLabel, you should definitely this one out.
• AGGeometryKit for arbitrary shape 3D transform code piece used in ZCDashLabel
