Simple use of Facebook POP Animation

Simple and practical POP Animation

It is better to find that the POP state is retained after the animation ends, and the block callback is used. You can use POPAnimatableProperty to quickly add basic animations or customize property animations.

Elastic Animation

-(Void) spring {

POPSpringAnimation * framePOP = [POPSpringAnimationanimationWithPropertyNamed: kPOPViewBackgroundColor];

FramePOP. springSpeed = 10.f;

FramePOP. springBounciness = 4.f;

FramePOP. toValue = [UIColorgreenColor];

[FramePOPsetCompletionBlock: ^ (POPAnimation * anim, BOOL finsih ){

If (finsih ){

NSLog (@ "view. frame = % @", NSStringFromCGRect (view. frame ));

}

}];

[Viewpop_addAnimation: framePOP forKey: @ "go"];

}

Animation slowdown

-(Void) Decay {

POPDecayAnimation * decay = [POPDecayAnimationanimationWithPropertyNamed: kPOPViewFrame];

// Decay. toValue = [NSValue valueWithCGRect: CGRectMake (200,400,100,100)];

Decay. velocity = [NSValuevalueWithCGRect: CGRectMake (200,300,100,100)];

[Viewpop_addAnimation: decay forKey: @ "go"];

}

Basic Animation

-(Void) basic {

POPBasicAnimation * basicAnimation = [POPBasicAnimationanimationWithPropertyNamed: kPOPLayerCornerRadius];

BasicAnimation. toValue = [NSNumbernumberWithFloat: CGRectGetHeight (view. frame)/2.];

BasicAnimation. timingFunction = [CAMediaTimingFunctionfunctionWithName: kCAMediaTimingFunctionEaseInEaseOut];

// BasicAnimation. duration = 3.f;

[BasicAnimationsetCompletionBlock: ^ (POPAnimation * ani, BOOL fin ){

If (fin ){

NSLog (@ "view. frame = % @", NSStringFromCGRect (view. frame ));

// POPBasicAnimation * newBasic = [POPBasicAnimation easeInEaseOutAnimation];

// NewBasic. property = [POPAnimatableProperty propertyWithName: kPOPLayerCornerRadius];

// NewBasic. toValue = [NSNumber numberWithFloat: 0];

// [View. layer pop_addAnimation: newBasic forKey: @ "go"];

}

}];

[View. layerpop_addAnimation: basicAnimation forKey: @ "frameChange"];

}

Composite Animation

-(Void) group

{

View. transform = CGAffineTransformMakeRotation (M_PI_2/3 );

POPBasicAnimation * spring = [POPBasicAnimationanimationWithPropertyNamed: kPOPLayerPositionY];

Spring. beginTime = CACurrentMediaTime ();

Spring. duration =. 4f;

Spring. fromValue = [NSNumbernumberWithFloat:-100.f];

Spring. toValue = [NSNumbernumberWithFloat: CGRectGetMinY (view. frame) + 80];

[SpringsetCompletionBlock: ^ (POPAnimation * ani, BOOL fin ){

}];

POPBasicAnimation * basic = [POPBasicAnimationanimationWithPropertyNamed: kPOPLayerRotation];

Basic. beginTime = CACurrentMediaTime ();

Basic. timingFunction = [CAMediaTimingFunctionfunctionWithName: kCAMediaTimingFunctionEaseInEaseOut];

Basic. toValue = [NSNumbernumberWithFloat:-M_PI_4];

Basic. duration =. 4f;

POPBasicAnimation * rotation = [POPBasicAnimationanimationWithPropertyNamed: kPOPLayerRotation];

Rotation. beginTime = CACurrentMediaTime () +. 4f;

Rotation. toValue = [NSNumbernumberWithFloat: 0.f];

Rotation. timingFunction = [CAMediaTimingFunctionfunctionWithName: kCAMediaTimingFunctionEaseInEaseOut];

Rotation. duration =. 25f;

POPBasicAnimation * donw = [POPBasicAnimationanimationWithPropertyNamed: kPOPLayerPositionY];

Donw. beginTime = CACurrentMediaTime () + 0.4f;

Donw. toValue = [NSNumbernumberWithFloat: CGRectGetMinY (view. frame)];

Donw. duration =. 25f;

Donw. timingFunction = [CAMediaTimingFunctionfunctionWithName: kCAMediaTimingFunctionEaseInEaseOut];

[View. layerpop_addAnimation: spring forKey: @ "spring"];

[View. layerpop_addAnimation: basic forKey: @ "basic"];

[View. layerpop_addAnimation: donw forKey: @ "down"];

[View. layerpop_addAnimation: rotation forKey: @ "rotation"];
