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)
POP2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。。。。。。
