进入本文章，相信大家都知道，iOS 动画 及 图形设计是iOS开发中的一大难点，本文主要讲解Fecebook 提供的 PoP 使用教程，提供PoP API 及 属性进行中文解释。以便大家更快的掌握 Fecebook PoP，不废话，马上进入话题，请往下看。
Pop是一个用于iOS，tvOS和OS X的可扩展的动画引擎。除了基本的静态动画，它支持弹簧和衰减动态动画，使它对建立真实的基于物理的交互有用。API允许快速集成现有的Objective-C代码库，并支持任何对象上的任何属性的动画。它是一个成熟和经过良好测试的框架，驱动纸张中的所有动画和过渡。
＃5步骤使用Facebook PoP＃
// 1.选择一种动画//
POPBasicAnimation POPSpringAnimation POPDecayAnimation
POPSpringAnimation * basicAnimation = [POPSpringAnimation animation];
// 2.决定天气，你会动画视图属性或图层特性，让我们选择一个视图属性并挑选kPOPViewFrame
//查看属性-
kPOPViewAlpha
kPOPViewBackgroundColor
kPOPViewBounds
kPOPViewCenter
kPOPViewFrame
kPOPViewScaleXY
kPOPViewSize
//图层属性-
kPOPLayerBackgroundColor
kPOPLayerBounds
kPOPLayerScaleXY
kPOPLayerSize
kPOPLayerOpacity
kPOPLayerPosition
kPOPLayerPositionX
kPOPLayerPositionY
kPOPLayerRotation
kPOPLayerBackgroundColorbasicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewFrame];
//3.计算出哪三种方法来设置toValue
//anim.toValue = @（1.0）;
//anim.toValue = [NSValue valueWithCGRect：CGRectMake（0，0，400，400）];
//anim.toValue = [NSValue valueWithCGSize：CGSizeMake（40，40）];
//basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（0，0，90，190）];
//4.为动画和设置代理创建名称basicAnimation.name =@“AnyAnimationNameYouWant”;basicAnimation.delegate = self
//5.添加动画到View或Layer，我们选择View so self.tableView而不是layer self.tableView.layer[self.tableViewpop_addAnimation：basicAnimationforKey：@“WhatEverNameYouWant”];
步骤1选择种类的动画
POPBasicAnimation
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.timingFunction = [CAMediaTimingFunctionfunctionWithName：kCAMediaTimingFunctionLinear];
//kCAMediaTimingFunctionLinear kCAMediaTimingFunctionEaseIn kCAMediaTimingFunctionEaseOut kCAMediaTimingFunctionEaseInEaseOut
POPSpringAnimation
POPSpringAnimation * springAnimation = [POPSpringAnimationanimation];springAnimation.velocity = @（1000）;
//每秒值单位的变化springAnimation.springBounciness =14;
//value between 0-20 default at 4springAnimation.springSpeed =3;//value between 0-20 default at 4
POPDecayAnimation
POPDecayAnimation * decayAnimation = [POPDecayAnimationanimation];decayAnimation.velocity = @（233）;
//每秒值单位变化decayAnimation.deceleration =。833;//范围0到1
例子
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];
步骤2决定是否对视图属性或图层属性进行动画处理
查看属性
Alpha-kPOPViewAlpha
颜色 - kPOPViewBackgroundColor
大小 - kPOPViewBounds
中心 - kPOPViewCenter
位置和大小 - kPOPViewFrame
大小 - kPOPViewScaleXY
大小（缩放） - kPOPViewSize
图层属性
颜色 - kPOPLayerBackgroundColor
大小 - kPOPLayerBounds
大小 - kPOPLayerScaleXY
大小 - kPOPLayerSize
不透明度 - kPOPLayerOpacity
位置 - kPOPLayerPosition
X位置 - kPOPLayerPositionX
Y位置 - kPOPLayerPositionY
旋转 - kPOPLayerRotation
颜色 - kPOPLayerBackgroundColor
例子
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];
注意：适用于任何Layer属性或从UIView继承的任何对象，如UIToolbar |UIPickerView |UIDatePicker |UIScrollView |UITextView |UIImageView |UITableViewCell |UIStepper |UIProgressView |UIActivityIndicatorView |UISwitch |UISlider |UITextField |UISegmentedControl |UIButton |UIView |UITableView
步骤3找到下面的属性，然后添加和设置.toValue
查看属性
Alpha-kPOPViewAlpha
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewAlpha];basicAnimation.toValue = @（0）;
//scale from 0 to 1
颜色 - kPOPViewBackgroundColor
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewBackgroundColor];basicAnimation.toValue = [UIColorredColor];
大小 - kPOPViewBounds
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewBounds];basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（0，0，90，190）];//前2个值不要
中心 - kPOPViewCenter
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewCenter];basicAnimation.toValue = [NSValuevalueWithCGPoint：CGPointMake（200，200）];
位置和大小 - kPOPViewFrame
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewFrame];basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（140，140，140，140）];
大小 - kPOPViewScaleXY
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewScaleXY];basicAnimation.toValue = [NSValuevalueWithCGSize：CGSizeMake（3，2）];
大小（缩放） - kPOPViewSize
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewSize];basicAnimation.toValue = [NSValuevalueWithCGSize：CGSizeMake（30，200）];
图层属性
颜色 - kPOPLayerBackgroundColor
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerBackgroundColor];basicAnimation.toValue = [UIColorredColor];
大小 - kPOPLayerBounds
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerBounds];basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（0，0，90，90）];//前2个值不要
大小 - kPOPLayerScaleXY
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerScaleXY];basicAnimation.toValue = [NSValuevalueWithCGSize：CGSizeMake（2，1）];//增加宽度和高度标度
大小 - kPOPLayerSize
POPBasicAnimation * basicAnimation = [POPBasicAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerSize];basicAnimation.toValue = [NSValuevalueWithCGSize：CGSizeMake（200，200）];
不透明度 - kPOPLayerOpacity
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerOpacity];basicAnimation.toValue = @（0）;
位置 - kPOPLayerPosition
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerPosition];basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（130，130，0，0）];//last 2 values dont matter
X位置 - kPOPLayerPositionX
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerPositionX];basicAnimation.toValue = @（240）;
Y位置 - kPOPLayerPositionY
POPSpringAnimation * anim = [POPSpringAnimationanimation];anim.property = [POPAnimatablePropertypropertyWithName：kPOPLayerPositionY];anim.toValue = @（320）;
旋转 - kPOPLayerRotation
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerRotation];basicAnimation.toValue = @（M_PI /4）;//2 M_PI是整个旋转
注意：属性更改适用于所有3种动画类型 - POPBasicAnimation POPSpringAnimation POPDecayAnimation
例子
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPLayerRotation];basicAnimation.toValue = @（M_PI /4）;//2 M_PI是整个旋转
步骤4为动画创建名称和委派
basicAnimation.name =@“WhatEverAnimationNameYouWant”;basicAnimation.delegate = self;
声明委托协议
委托方法
- （void）pop_animationDidStart：（POPAnimation *）anim;
- （void）pop_animationDidStop：（POPAnimation *）anim finished :(BOOL）finished;
- （void）pop_animationDidReachToValue：（POPAnimation *）anim;
例子
POPSpringAnimation * basicAnimation = [POPSpringAnimationanimation];basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewFrame];basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（0，0，90，190）];basicAnimation.name =@“WhatEverAnimationNameYouWant”;basicAnimation.delegate = self;
步骤5添加动画到查看
[self.tableViewpop_addAnimation：basicAnimationforKey：@“WhatEverNameYouWant”];
例子
POPSpringAnimation * basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatablePropertypropertyWithName：kPOPViewFrame];
basicAnimation.toValue = [NSValuevalueWithCGRect：CGRectMake（0，0，90，190）];
basicAnimation.name =@“SomeAnimationNameYouChoose”;
basicAnimation.delegate = self;
[self.tableViewpop_addAnimation：basicAnimationforKey：@“WhatEverNameYouWant”];
