1、Core Animation
Core Animation了赵，即為核心動(dòng)畫，它是一組非常強(qiáng)大的動(dòng)畫處理API甸赃，使用它能做出非常炫麗的動(dòng)畫效果柿汛，而且往往是事半功倍。也就是說埠对，使用少量的代碼就可以實(shí)現(xiàn)非常強(qiáng)大的功能络断。Core Animation可以用在Mac OS X和iOS平臺。Core Animation的動(dòng)畫執(zhí)行過程都是在后臺操作的项玛，不會(huì)阻塞主線程貌笨。要注意的是，Core Animation是直接作用在CALayer上的襟沮，并非UIView锥惋。
QuartzCore.framework框架
CAAnimation{
? ? ? ? CAPropertyAnimation{
? ? ? ? ? ? CABasicAnimation{

? ? ? ? ? ? CAKeyframeAnimation

CAAnimation是所有動(dòng)畫對象的父類昌腰，負(fù)責(zé)控制動(dòng)畫的持續(xù)時(shí)間和速度，是個(gè)抽象類膀跌，不能直接使用遭商，應(yīng)該使用它具體的子類。
CAPropertyAnimation捅伤，是CAAnimation的子類株婴，也是個(gè)抽象類，要想創(chuàng)建動(dòng)畫對象暑认，應(yīng)該使用它的兩個(gè)子類：CABasicAnimation和CAKeyframeAnimation。
CABasicAnimation大审，是CAPropertyAnimation的子類蘸际，其子類是CASpringAnimation，它主要用于制作比較單一的動(dòng)畫徒扶，例如粮彤，平移、縮放姜骡、旋轉(zhuǎn)导坟、顏色漸變、邊框的值的變化等圈澈，也就是將layer的某個(gè)屬性值從一個(gè)值到另一個(gè)值的變化惫周。類似x -> y這種變化，然而對于x -> y -> z甚至更多的變化是不行的康栈。
1.移動(dòng)動(dòng)畫
UIView*moveView = [[UIViewalloc]initWithFrame:CGRectMake(100,100,100,100)];
? ? moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:moveView];
? ? CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position"];
? ? animation.duration=2;
? ? animation.repeatCount=2;
? ? animation.beginTime=CACurrentMediaTime() +1;// 1秒后執(zhí)行
? ? animation.fromValue= [NSValuevalueWithCGPoint:moveView.layer.position];//?起始幀
? ? animation.toValue=
? ? [NSValue?valueWithCGPoint:CGPointMake(300, 300)];?//?終了幀
? ? // 視圖添加動(dòng)畫
? ? [moveView.layeraddAnimation:animationforKey:@"move"];
2.旋轉(zhuǎn)動(dòng)畫
UIView*moveView = [[UIViewalloc]initWithFrame:CGRectMake(100,100,100,100)];
? ? moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:moveView];
? ? //?對Y軸進(jìn)行旋轉(zhuǎn)（指定Z軸的話递递，就和UIView的動(dòng)畫一樣繞中心旋轉(zhuǎn)）
? ? CABasicAnimation*animation?=
? ? [CABasicAnimation?animationWithKeyPath:@"transform.rotation.y"];
? ? animation.duration=2;
? ? animation.repeatCount=2;
? ? animation.beginTime=CACurrentMediaTime() +1;// 1秒后執(zhí)行
? ? animation.fromValue=?[NSNumbernumberWithFloat:0.0];//?起始角度
? ? animation.toValue=?[NSNumbernumberWithFloat:M_PI];//?終止角度
? ? [moveView.layeraddAnimation:animationforKey:@"rotate"];
3.縮放動(dòng)畫
UIView*moveView = [[UIViewalloc]initWithFrame:CGRectMake(100,100,100,100)];
? ? moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:moveView];
? ? CABasicAnimation*animation?=
? ? [CABasicAnimation?animationWithKeyPath:@"transform.scale"];
? ? animation.duration=2.5;//?動(dòng)畫持續(xù)時(shí)間
? ? animation.repeatCount=2;//?重復(fù)次數(shù)
? ? animation.fromValue=?[NSNumbernumberWithFloat:1.0];//?開始時(shí)的倍率
? ? animation.toValue=?[NSNumbernumberWithFloat:2.0];//?結(jié)束時(shí)的倍率
? ? [moveView.layeraddAnimation:animationforKey:@"scale"];
4.漸隱動(dòng)畫
UIView*moveView = [[UIViewalloc]initWithFrame:CGRectMake(100,100,100,100)];
? ? moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:moveView];
? ? //opacity 指layer的透明度
? ? CABasicAnimation *basicAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
? ? basicAnimation.fromValue=@(1.0);
? ? basicAnimation.toValue?= @(0.0);//[NSNumber numberWithFloat:0.0]
? ? basicAnimation.repeatCount=2;
? ? basicAnimation.duration=2;
? ? [moveView.layeraddAnimation:basicAnimationforKey:@"op"];
4.顏色漸變
UIView*moveView = [[UIViewalloc]initWithFrame:CGRectMake(100,100,100,100)];
? ? moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:moveView];
? ? CABasicAnimation?* animation?=?[CABasicAnimation?animationWithKeyPath:@"backgroundColor"];
? ? animation.duration=2;
? ? animation.repeatCount=2;
? ? animation.beginTime=CACurrentMediaTime() +1;// 1秒后執(zhí)行
? ? animation.fromValue=?(__bridgeid_Nullable)([UIColorredColor].CGColor);
? ? animation.toValue=?(__bridgeid_Nullable)([UIColorpurpleColor].CGColor);
? ? [moveView.layeraddAnimation:animationforKey:@"bgcolor"];
5.組合動(dòng)畫
UIView*moveView = [[UIViewalloc]initWithFrame:CGRectMake(100,100,100,100)];
? ? moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:moveView];
? ? CABasicAnimation?* animation1?= [CABasicAnimation?animationWithKeyPath:@"transform.translation.x"];
? ? animation1.toValue=?[NSNumbernumberWithFloat:80];;//?終點(diǎn)
? ? CABasicAnimation?* animation2?=[CABasicAnimation?animationWithKeyPath:@"transform.translation.z"];
? ? animation2.fromValue=?[NSNumbernumberWithFloat:0.0];//?開始時(shí)的角度
? ? animation2.toValue=?[NSNumbernumberWithFloat:M_PI];//?結(jié)束時(shí)的角度
? ? /*?動(dòng)畫組?*/
? ? CAAnimationGroup?*group?=?[CAAnimationGroup?animation];
? ? group.duration=1.0;
? ? group.repeatCount=1;
? ? group.animations=
? ? [NSArrayarrayWithObjects:animation1,?animation2,nil];
? ? [moveView.layeraddAnimation:groupforKey:@"move-rotate"];
觸摸控制
-(void)move:(CGPoint)position{
? ? CASpringAnimation *animation = [CASpringAnimation animationWithKeyPath:@"position"];
? ? animation.fromValue= [NSValuevalueWithCGPoint:self.moveView.center];
? ? animation.toValue= [NSValuevalueWithCGPoint:position];
? ? //? ? 設(shè)置fillModel 必須設(shè)置 removedOnCompletion
? ? animation.removedOnCompletion = NO;
? ? animation.fillMode = kCAFillModeBoth;
? ? [self.moveView.layeraddAnimation:animationforKey:@"move"];
}
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent*)event{
? ? [self move:[[touches anyObject]locationInView:self.view]];
}
停在終點(diǎn)
animation.removedOnCompletion = NO;
? ? animation.fillMode = kCAFillModeForwards;
捕獲動(dòng)畫開始時(shí)和終了時(shí)的事件
-?(void)animationDidStart:(CAAnimation?*)theAnimation {
?}
-?(void)animationDidStop:(CAAnimation?*)theAnimation?finished:(BOOL)flag {
?}

? ? self.moveView.backgroundColor = [UIColor redColor];
? ? [self.viewaddSubview:self.moveView];
? ? CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
? ? //創(chuàng)建一個(gè)CGPathRef對象登舞，就是動(dòng)畫的路線

一般推薦UI框架自帶的貝塞爾曲線，可以用以下代碼替換CGMutablePathRef那一段悬荣，代碼如下：
// ②.1創(chuàng)建路徑
? ? UIBezierPath * path = [UIBezierPath bezierPathWithRect:CGRectMake(75, 75, 200, 200)];
? ? // ②.2設(shè)置路徑的屬性
? ? // ②.3將路徑設(shè)置給動(dòng)畫
? ? [animation setPath:path.CGPath];
創(chuàng)建一個(gè)模仿刪除App的晃動(dòng)動(dòng)畫：
// ①.初始化動(dòng)畫屬性
? ? CAKeyframeAnimation * animation = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation"];// 旋轉(zhuǎn)（旋轉(zhuǎn)搖晃）
? ? // ②.設(shè)置動(dòng)畫屬性 ??思路：搖晃菠秒，從一個(gè)點(diǎn)，搖晃到另一個(gè)點(diǎn)
? ? // ②.1定義角度值
? ? // NSArray * array = @[角度數(shù)值]
? ? CGFloat angle = M_PI_4 / 9.0;// 每次抖動(dòng)5度
? ? NSArray * array = @[@(angle),@(-angle),@(angle)];// 開始角度氯迂，經(jīng)過角度践叠，回復(fù)角度 相當(dāng)于 左、右囚戚、左 然后重復(fù)
? ? // ②.2設(shè)置動(dòng)畫數(shù)組
? ? [animation setValues:array];
? ? // 修改動(dòng)畫的填充方法
? ? [animation setFillMode:kCAFillModeForwards];
? ? [animation setRemovedOnCompletion:NO];
? ? // 設(shè)置時(shí)長
? ? animation.duration = 0.2f;
? ? // 設(shè)置重復(fù)
? ? [animation setRepeatCount:MAXFLOAT];
? ? // 反轉(zhuǎn)動(dòng)畫
? ? // ③.將動(dòng)畫添加到圖層
? ? [demoView.layer addAnimation:animation forKey:nil];
CAAnimationGroup酵熙，CAAnimation的子類，可以保存一組動(dòng)畫對象驰坊，將CAAnimationGroup對象加入層后匾二，組中所有動(dòng)畫對象可以同時(shí)并發(fā)運(yùn)行

Damping ratios less than 1 will oscillate more and more before coming to a complete stop. You can use the initial spring velocity to specify how fast the object at the end of the simulated spring was moving before it was attached.

3.轉(zhuǎn)場動(dòng)畫
? ? //單視圖轉(zhuǎn)場動(dòng)畫
? ? + (void)transitionWithView:(UIView *)view
duration:(NSTimeInterval)duration
options:(UIViewAnimationOptions)options
animations:(void(^__nullable)(void))animations
completion:(void(^__nullable)(BOOLfinished))completion
? ? //雙視圖轉(zhuǎn)場動(dòng)畫
? ? + (void)transitionFromView:(UIView *)fromView
toView:(UIView *)toView
duration:(NSTimeInterval)duration
options:(UIViewAnimationOptions)options
completion:(void(^__nullable)(BOOLfinished))completion
這兩個(gè)都是轉(zhuǎn)場動(dòng)畫,不同的是第一個(gè)是單視圖轉(zhuǎn)場,第二個(gè)是雙視圖轉(zhuǎn)場.不過需要注意的是:單視圖轉(zhuǎn)場動(dòng)畫只能用作屬性動(dòng)畫做不到的轉(zhuǎn)場效果,比如屬性動(dòng)畫不能給UIImageview的image賦值操作做動(dòng)畫效果等.
