我的POP动画学习之路

作者: 楚雄天下 | 来源:发表于2017-08-22 10:56 被阅读76次

    作为一个菜鸟,在我刚进入ios这个坑的时候,动画对我来说好像很高大上,很遥远,但是事实却是真的很高大上很遥远,为了纪念我的动画学习之路,特书此文,以表......

    一、导入POP框架

    1.CocoaPods方法导入 

    直接 pod ‘pop’ 或者 pod 'pop',:git => 'https://github.com/facebook/pop.git'

    2.没有CocoaPods导入方法 首先下载POP这个框架,可在这https://github.com/facebook/pop 下载,下载完之后添加到你的工程里。注意,记得把工程的Other Linker Flags 选项添加 “-lc++”;(如图POP1所示)

    POP1

    二、POP的使用在这里只列举少部分例子 

    1.第一步是导入头文件 #import遵循协议

    例子1:弹性扩张动画

    首先创建一个动画动作的View

    self.popView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];

    self.popView.center = self.view.center;

    self.popView.backgroundColor = [UIColor greenColor];

    self.popView.layer.cornerRadius = self.popView.frame.size.width *0.5;

    [self.view addSubview:self.popView];

    然后就是创建弹性动画,代码如下

    POPSpringAnimation * springAnimation = [POPSpringAnimation animationWithPropertyNamed:kPOPViewScaleXY];

    springAnimation.name = @"222222";

    springAnimation.delegate = self;

    springAnimation.toValue            = [NSValue valueWithCGPoint:CGPointMake(1, 1)];

    springAnimation.velocity            = [NSValue valueWithCGPoint:CGPointMake(-2, -2)];

    springAnimation.springBounciness    = 20.f;

    springAnimation.springSpeed        = 10.f;

    springAnimation.dynamicsTension    = 700.f;//动态张力

    springAnimation.dynamicsFriction    = 7.f;//摩擦

    springAnimation.dynamicsMass        = 3.f;//动态质量

    [self.popView pop_addAnimation:springAnimation forKey:nil];

    监听动画结束可以实现其协议方法里的

    -(void)pop_animationDidStop:(POPAnimation *)anim finished:(BOOL)finished方法

    例子2:旋转动画

    POPSpringAnimation *spin = [POPSpringAnimation animationWithPropertyNamed:kPOPLayerRotation];

    spin.fromValue = @(M_PI / 4);

    spin.toValue = @(0);

    spin.springBounciness = 20;

    spin.velocity = @(10);

    [self.popView.layer pop_addAnimation:spin forKey:@"likeAnimation"];

    例子3:膨胀

    POPSpringAnimation *sprintAnimation = [POPSpringAnimation animationWithPropertyNamed:kPOPViewScaleXY];

    sprintAnimation.velocity = [NSValue valueWithCGPoint:CGPointMake(8, 8)];

    sprintAnimation.springBounciness = 20.f;

    sprintAnimation.name = @"1233";

    //    sprintAnimation.delegate = self;

    [bt pop_addAnimation:sprintAnimation forKey:@"sendAnimation"];

    注意:有没有发现,其实这几个动画除了参数不一样外,最大的区别就是animationWithPropertyNamed:这里这个Name不一样,所以决定不同动画就用不同的Name,其它参数就可以按自己的需求实际来设计了

    例子一:UITableViewCell 动画

    要在UITableViewCell 上添加动画,其实也不难,效果就是当我们点击某一个cell的时候,动画就开始,在这个例子中,我们给cell添加两个动画,一个是放大与缩回动画。

    要重写UITableViewCell的-(void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated方法,在该方法中添加代码如下:

    -(void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated

    {

    [super setHighlighted:highlighted animated:animated];

    if (self.highlighted) {

    POPBasicAnimation *scaleAnimation = [POPBasicAnimation animationWithPropertyNamed:kPOPViewScaleXY];

    scaleAnimation.duration = 0.1;

    scaleAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(1, 1)];

    [self.textLabel pop_addAnimation:scaleAnimation forKey:@"scalingUp"];

    } else {

    POPSpringAnimation *sprintAnimation = [POPSpringAnimation animationWithPropertyNamed:kPOPViewScaleXY];

    sprintAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(0.9, 0.9)];

    sprintAnimation.velocity = [NSValue valueWithCGPoint:CGPointMake(2, 2)];

    sprintAnimation.springBounciness = 50.f;

    [self.textLabel pop_addAnimation:sprintAnimation forKey:@"springAnimation"];

    }

    }

    如此即可实现cell动画,动画效果如下图POP2(这个动画效果图是网上盗用的:http://www.jianshu.com/p/47ce70f3bf59)

    总结:说了那么多,是时候该来总结一下了,POP 动画的简单应用方法都是大同小异,主要是区分 animationWithPropertyNamed:这个方法,现在总结一下这个方法的种类:

    时间问题,先写到这,以后接着写转场动画等例子。。。。。。
