【IOS】扩展UIImageViewEx实现：手势移动,旋转,缩放（附带一个收缩的文字标签功能）

#import #import typedef enum{ UIImageExNormal = 0, UIImageExFull }UIImageExState; @interface UIImageViewEx : UIImageView { UIView *parentview; //父窗口，即用将UIImageEx所加到的UIView BOOL isPanEnable; //是否可以移动 BOOL isPinchEnable; //是否可以放大缩小 BOOL isRotateEnable; //是否可以旋转 BOOL isTap; //是否可以点击触摸 UIImageExState imageState; //图片当前状态 CGFloat imageScale; //最大缩放的倍数 CGFloat imageSize; //记录图片的累计缩放 CGFloat imageRotation; //记录图片的原始角度 CGPoint imagePoint; //记录图片的原始位置 UITextView *textView; //动态弹出的文本 } @property (nonatomic,retain) UIView *parentview; @property (nonatomic) CGFloat imageSize; @property (nonatomic) CGFloat imageRotation; @property (nonatomic) CGPoint imagePoint; @property BOOL isPanEnable; @property BOOL isRotateEnable; @property BOOL isPinchEnable; @property BOOL isTap; - (void)handlePan:(UIPanGestureRecognizer *)recognizer; - (void)handlePinch:(UIPinchGestureRecognizer *)recognizer; - (void)handleRotate:(UIRotationGestureRecognizer *)recognizer; - (void)handleTap:(UITapGestureRecognizer *)recognizer; //必须设置的 - (void)setScaleAndRotation:(UIView*)imageView; - (void)setInfoText:(NSString *)string; - (void)setShadow:(BOOL)isShadow; @end
