5 Steps For Using Facebook Pop
// 1. Pick a Kind Of Animation // POPBasicAnimation POPSpringAnimation POPDecayAnimation
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
// 2. Decide weather you will animate a view property or layer property, Lets pick a View Property and pick kPOPViewFrame
// View Properties - kPOPViewAlpha kPOPViewBackgroundColor kPOPViewBounds kPOPViewCenter kPOPViewFrame kPOPViewScaleXY kPOPViewSize
// Layer Properties - kPOPLayerBackgroundColor kPOPLayerBounds kPOPLayerScaleXY kPOPLayerSize kPOPLayerOpacity kPOPLayerPosition kPOPLayerPositionX kPOPLayerPositionY kPOPLayerRotation kPOPLayerBackgroundColor
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewFrame];
// 3. Figure Out which of 3 ways to set toValue
// anim.toValue = @(1.0);
// anim.toValue = [NSValue valueWithCGRect:CGRectMake(0, 0, 400, 400)];
// anim.toValue = [NSValue valueWithCGSize:CGSizeMake(40, 40)];
basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(0, 0, 90, 190)];
// 4. Create Name For Animation & Set Delegate
basicAnimation.name=@"AnyAnimationNameYouWant";
basicAnimation.delegate=self
// 5. Add animation to View or Layer, we picked View so self.tableView and not layer which would have been self.tableView.layer
[self.tableView pop_addAnimation:basicAnimation forKey:@"WhatEverNameYouWant"];
Step 1 Pick Kind of Animation(选择一种动画类别)
1，
POPBasicAnimation （基本）动效可以在给定时间的运动中插入数值调整运动节奏
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.timingFunction=[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
// kCAMediaTimingFunctionLinear kCAMediaTimingFunctionEaseIn kCAMediaTimingFunctionEaseOut kCAMediaTimingFunctionEaseInEaseOut
2，
POPSpringAnimation （弹性）动效可以赋予物体愉悦的弹性效果
POPSpringAnimation *springAnimation = [POPSpringAnimation animation];
springAnimation.velocity=@(1000); // change of value units per second
springAnimation.springBounciness=14; // value between 0-20 default at 4
springAnimation.springSpeed=3; // value between 0-20 default at 4
3，
POPDecayAnimation （衰减) 动效可以用来逐渐减慢物体的速度至停止
Step 2 Decide if you will animate a view property or layer property （步骤2决定是否将动画视图属性或图层属性）
View Properties
Alpha - kPOPViewAlpha
Color - kPOPViewBackgroundColor
Size - kPOPViewBounds
Center - kPOPViewCenter
Location & Size - kPOPViewFrame
Size - kPOPViewScaleXY
Size(Scale) - kPOPViewSize
Layer Properties
Color - kPOPLayerBackgroundColor
Size - kPOPLayerBounds
Size - kPOPLayerScaleXY
Size - kPOPLayerSize
Opacity - kPOPLayerOpacity
Position - kPOPLayerPosition
X Position - kPOPLayerPositionX
Y Position - kPOPLayerPositionY
Rotation - kPOPLayerRotation
Color - kPOPLayerBackgroundColor
Step 3 Find your property below then add and set .toValue （步骤3找到下面你的财产，然后添加和设置。价值）
View Properties （View 属性）
Alpha - kPOPViewAlpha （透明度）
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewAlpha];
basicAnimation.toValue= @(0); // scale from 0 to 1
Color - kPOPViewBackgroundColor（颜色）
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPViewBackgroundColor];
basicAnimation.toValue= [UIColor redColor];
Size - kPOPViewBounds（大小）
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewBounds];
basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(0, 0, 90, 190)]; //first 2 values dont matter
Center - kPOPViewCenter（中心点）
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewCenter];
basicAnimation.toValue=[NSValue valueWithCGPoint:CGPointMake(200, 200)];
Location & Size - kPOPViewFrame（位置和大小）
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewFrame];
basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(140, 140, 140, 140)];
Size - kPOPViewScaleXY（还是大小）
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewScaleXY];
basicAnimation.toValue=[NSValue valueWithCGSize:CGSizeMake(3, 2)];
Size(Scale) - kPOPViewSize（大小）
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewSize];
basicAnimation.toValue=[NSValue valueWithCGSize:CGSizeMake(30, 200)];
Layer Properties（Layer 属性）（同上）
Color - kPOPLayerBackgroundColor
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerBackgroundColor];
basicAnimation.toValue= [UIColor redColor];
Size - kPOPLayerBounds
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerBounds];
basicAnimation.toValue= [NSValue valueWithCGRect:CGRectMake(0, 0, 90, 90)]; //first 2 values dont matter
Size - kPOPLayerScaleXY
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerScaleXY];
basicAnimation.toValue= [NSValue valueWithCGSize:CGSizeMake(2, 1)];//increases width and height scales
Size - kPOPLayerSize
POPBasicAnimation *basicAnimation = [POPBasicAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPLayerSize];
basicAnimation.toValue= [NSValue valueWithCGSize:CGSizeMake(200, 200)];
Opacity - kPOPLayerOpacity
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerOpacity];
basicAnimation.toValue = @(0);
Position - kPOPLayerPosition
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerPosition];
basicAnimation.toValue= [NSValue valueWithCGRect:CGRectMake(130, 130, 0, 0)];//last 2 values dont matter
X Position - kPOPLayerPositionX
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerPositionX];
basicAnimation.toValue= @(240);
Y Position - kPOPLayerPositionY
POPSpringAnimation *anim = [POPSpringAnimation animation];
anim.property=[POPAnimatableProperty propertyWithName:kPOPLayerPositionY];
anim.toValue = @(320);
Rotation - kPOPLayerRotation
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerRotation];
basicAnimation.toValue= @(M_PI/4); //2 M_PI is an entire rotation
Note: Property Changes work for all 3 animation types - POPBasicAnimation POPSpringAnimation POPDecayAnimation
Example （例子）
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName: kPOPLayerRotation];
basicAnimation.toValue= @(M_PI/4); //2 M_PI is an entire rotation
Step 4 Create Name & Delegate For Animation（创建一个名字和设置代理）
basicAnimation.name=@"WhatEverAnimationNameYouWant";
basicAnimation.delegate=self;
Declare Delegate Protocol <POPAnimatorDelegate>(别忘了代理)
三个代理方法
- (void)pop_animationDidStart:(POPAnimation *)anim;
- (void)pop_animationDidStop:(POPAnimation *)anim finished:(BOOL)finished;
- (void)pop_animationDidReachToValue:(POPAnimation *)aim;
例子：
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewFrame];
basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(0, 0, 90, 190)];
basicAnimation.name=@"WhatEverAnimationNameYouWant";
basicAnimation.delegate=self;
Step 5 Add animation to View（把动画加到View上面）
[self.yourview pop_addAnimation:basicAnimation forKey:@"WhatEverNameYouWant"];
完整的例子：
⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️
POPSpringAnimation *basicAnimation = [POPSpringAnimation animation];
basicAnimation.property = [POPAnimatableProperty propertyWithName:kPOPViewFrame];
basicAnimation.toValue=[NSValue valueWithCGRect:CGRectMake(0, 0, 90, 190)];
basicAnimation.name=@"SomeAnimationNameYouChoose";
basicAnimation.delegate=self;
[self.tableView pop_addAnimation:basicAnimation forKey:@"WhatEverNameYouWant"];
