CABasicAnimation动画

CABasicAnimation是基于CALayer的动画，有各种形式的动画，这种动画已经趋于底层了，所以灵活性很强。
添加CoreGraphics.framework，QuartzCore.framework，类库。
延展，可在视频的layer层增加一些动画或者贴纸：

#import <Foundation/Foundation.h>
//
#if defined(NS_STRING_ENUM)  // Available starting in Xcode 8.0.
#define SRICKER_STRING_ENUM NS_STRING_ENUM
#else
#define SRICKER_STRING_ENUM
#endif
typedef NSString *StickerAnimationType SRICKER_STRING_ENUM;
typedef NS_ENUM(NSInteger, StickerTransformLocal) {
    StickerTransformAll,///x.y
    StickerTransformX,  ///x.
    StickerTransformY,     ///y.
    StickerTransformZ,    ///z.
};
@interface StickerDefault : NSObject

//缩放

//旋转
