Core Animation :
Core Animation是直接作用在CALayer上的,并非UIView.
一.使用步骤
http://www.cnblogs.com/mjios/archive/2013/04/15/3021039.html
具体:
CAAnimation:继承NSObject,实现的代理有NSCoding,NSCopying,CAMediaTiming,CAAction
类方法:
//创建一个新的动画对象
+ (instancetype)animation;
//Animations implement the same property model as defined by CALayer.See CALayer.h for more details.
+ (nullable id)defaultValueForKey:(NSString *)key;
方法:
- (BOOL)shouldArchiveValueForKey:(NSString *)key;
属性:
动画切入方式 timingFunction
Delegate:
- (void)animationDidStart:(CAAnimation *)anim;
- (void)animationDidStop:(CAAnimation *)anim;
CAAnimation's SubClass: CAPropertyAnimation
类方法:
//Creates a new animation object with its 'keyPath' property set to 'path'
+ (instancetype)animationWithKeyPath:(nullable NSString *)path;
属性:
动画描述:keyPath
设置动画:CAValueFunction * valueFunction
CAPropertyAnimation's SubClass: CABasicAnimation
@property(nullable,strong)idfromValue;
@property(nullable,strong)idtoValue;
@property(nullable,strong)idbyValue;
CAPropertyAnimation's subClass CAPropertyAnimation
属性太多看官方文档吧.
重要!!!!
