IOS instance CALayer layer animation click

IOSInstanceCALayerLayerAnimationClick here to introduce the content of this article.CALayerCan achieve complexAnimationEffect, at the same timeCALayerYou need to clickCALayerClick object. The following describes the implementation results and processes. :

Implementation process:

 
 

  
  
# Import "AnimView. h"
  
  
@ Implementation AnimView
  
  
 
  
  
-(Id) initWithFrame :( CGRect) frame {
  
  

  
  
Self = [super initWithFrame: frame];
  
  
If (self ){
  
  
[Self setBackgroundColor: [UIColor clearColor];
  
  
UITapGestureRecognizer * tapGesture = [[UITapGestureRecognizer alloc] initWithTarget: self action: @ selector (touchesPoint :)];
  
  
[Self addGestureRecognizer: tapGesture];
  
  
[TapGesture release];
  
  
}
  
  
Return self;
  
  
}
  
  
-(Void) drawRect :( CGRect) rect
  
  
{
  
  
[NSTimer scheduledTimerWithTimeInterval: 5 target: self selector: @ selector (stratAnim :) userInfo: nil repeats: NO];
  
  
}
  
  
-(Void) stratAnim :( id) sender
  
  
{
  
  
// Add Layer
  
  
Layer2 = [CALayer layer];
  
  
[Layer2 setBackgroundColor: [[UIColor redColor] CGColor];
  
  
Layer2.bounds = CGRectMake (0, 0, 60, 40); // set the layer to the image size.
  
  
Layer2.position = CGPointMake (25, 25); // The Position of the layer in the view
  
  
[Self. layer addSublayer: layer2]; // Add the layer to the default layer of the current View.
  
  

  
  
[Self startFlyStarAnimation];
  
  
}
  
  
-(Void) startFlyStarAnimation
  
  
{
  
  
// Motion Track
  
  
CGMutablePathRef thePath = CGPathCreateMutable ();
  
  
CGPathMoveToPoint (thePath, NULL, self. center. x, self. center. y );
  
  
CGPathAddLineToPoint (thePath, NULL, self. center. x, self. center. y-45 );
  
  
CGPathAddLineToPoint (thePath, NULL, self. center. x, self. center. y + 45 );
  
  
CGPathAddLineToPoint (thePath, NULL, self. center. x, self. center. y );
  
  

  
  
// Add an animation
  
  
CAKeyframeAnimation * animation;
  
  
Animation = [CAKeyframeAnimation animationWithKeyPath: @ "position"];
  
  
Animation. path = thePath;
  
  
Animation. duration = 3.0;
  
  
Animation. repeatCount = 2;
  
  
CFRelease (thePath );
  
  
[Animation setDelegate: self];
  
  
// [Self animationDidStop: animation finished: YES];
  
  
[Animation setTimingFunction: [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionLinear];
  
  
[Layer2 addAnimation: animation forKey: kCATransition];
  
  
}
  
  
// Stop the animation
  
  
-(Void) animationDidStop :( CAAnimation *) anim finished :( BOOL) flag
  
  
{
  
  
NSLog (@ ">>>> animation stopped ");
  
  
}
  
  
// Touch event
  
  
-(Void) touchesPoint :( UITapGestureRecognizer *) gestureRecognizer
  
  
{
  
  
CGPoint locationInView = [gestureRecognizer locationInView: self];
  
  
// The animation layer of the presentationLayer
  
  
CALayer * layer1 = [[layer2 presentationLayer] hitTest: locationInView];
  
  
If (layer1! = Nil ){
  
  
NSLog (@ "click the moving layer ");
  
  
}
  
  
}
  
  
-(Void) dealloc {
  
  
[Super dealloc];
  
  
}
  
  
@ End
 
 

The presentationLayer is the position layer of the CALayer animation.
