源码NRTextTransitions，NRTextTransitions可轻松处理UILabel、UITextView以及UITextField中的文本过渡动画。NRTextTransitions使用了和UIView类方法相似的API。 Basic, block based, text transitions NRTextTransitions is a category in UIView that makes easier handling animated text transitions for UILabel, UITextView and UITextField. As the standard +[UIView animateWithDuration:animations:] is not able to animate non-animatable properties, and text, font and textColor properties of UILabel, UITextView and UITextField, are non-animatable, you need to use CATransition to do so with animation.
