简单实用POP动画

发现POP比较好的一点是保留了动画结束后的状态，通过block回调。使用POPAnimatableProperty 可以快速添加基本动画，也可以自定义属性动画。

弹性动画

- (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"];

}

减缓动画

- (void)Decay{

    POPDecayAnimation* decay = [POPDecayAnimationanimationWithPropertyNamed:kPOPViewFrame];

//    decay.toValue = http://www.mamicode.com/[NSValue valueWithCGRect:CGRectMake(200, 400, 100, 100)];

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

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

}

基本动画

-(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 = http://www.mamicode.com/[NSNumber numberWithFloat:0];

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

        }

    }];

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

}

组合动画

-(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"];

}
