1. Alloc the instance

    _maker = [[BMWaveMaker alloc] init];
   

2. Assign the detination view

   This step is necessary, other wise, the maker will not have the animation and also throw out the warning message;

      _maker.animationView = self.view;
   

3. Use the Methods https://momolens.co/

   Span Wave

      - (void)spanWave; //span a single wave
   
      /**
       *  span numerous waves
       *
       *  @param timeInteral waves cycle
       */
      - (void)spanWaveContinuallyWithTimeInterval:(NSTimeInterval)timeInterval;
   

   Stop Wave

      /**
       *  stop wave animation
       *
       *  @param immediately - if the value is YES, the waves will be removed immediately, otherwise, they'll be removed automatically
       */
      - (void)stopWaveImmediately:(BOOL)immediately;
   
      /**
       *  stop wave animation;  
       *  same as  [waveMaker stopWaveImmediately:NO];
       */
      - (void)stopWave;
   

4. Parameters Explaintions

     /**
      *  the view which will add the animations;
      */
     @property (nonatomic, weak) UIView *animationView;
   
     /**
      *  the center of the wave, default is the View's center;
      */
     @property (nonatomic, assign) CGPoint waveCenter;
   
     /**
      *  wave's width, default is 2.0f;
      */
     @property (nonatomic, assign) CGFloat wavePathWidth;
   
     /**
      *  span animation duration, default is 1.0f;
      */
     @property (nonatomic, assign) CGFloat animationDuration;
   
     /**
      *  wave's color - Arc's color, default is [UIColor blueColor];
      */
     @property (nonatomic, strong) UIColor *waveColor;
   
     /**
      *  the origin wave layer's radius, not contains the board width;
      *  default value is 20.0f;
      */
     @property (nonatomic, assign) CGFloat originRadius;
   
     /**
      *  The following two property is used for calculating the final wave's size.
      *  The properties are alternative, if they are setted the value at the same time,
      *  the property spanSale is valid and the finalRadius property will be ignored.
      */
   
     ///Zoom in scale, the value should be greater than 1.0f;
     @property (nonatomic, assign) CGFloat spanScale;
     ///Zoom in final radius, the value should be greater than originRadius, if not, the value will be originRadius * 2;
     @property (nonatomic, assign) CGFloat finalRadius;
   
     /**
      *  the color filled in the wave;
      */
     @property (nonatomic, assign) UIColor *waveFillColor;
   
     /**
      *  the stauts suggested that if the view has waves waving;
      */
     @property (nonatomic, readonly) BOOL isWaving;
