V 2.5.0 (⚠️ Important)

• 添加 cancenButtonIndex 属性。在 cancelTitle.length > 0 的情况下始终返回 0，否则返回 -1：

  @interface LCActionSheet : UIView
  
  @property (nonatomic, assign, readonly) NSInteger cancelButtonIndex;

• 修改 Block 属性命名：

  @property (nonatomic, copy) LCActionSheetClickedBlock     clickedBlock;
  @property (nonatomic, copy) LCActionSheetWillPresentBlock willPresentBlock;
  @property (nonatomic, copy) LCActionSheetDidPresentBlock  didPresentBlock;
  @property (nonatomic, copy) LCActionSheetWillDismissBlock willDismissBlock;
  @property (nonatomic, copy) LCActionSheetDidDismissBlock  didDismissBlock;
  
  ->
  
  @property (nonatomic, copy) LCActionSheetClickedHandle     clickedHandle;
  @property (nonatomic, copy) LCActionSheetWillPresentHandle willPresentHandle;
  @property (nonatomic, copy) LCActionSheetDidPresentHandle  didPresentHandle;
  @property (nonatomic, copy) LCActionSheetWillDismissHandle willDismissHandle;
  @property (nonatomic, copy) LCActionSheetDidDismissHandle  didDismissHandle;
