UIView动画

改变UIView的frame:

- (IBAction)changeFrame:(id)sender {
    //UIView动画有开始beginAnimation, 有结束commitAnimation
    //第一步:开始UIview动画
    [UIView beginAnimations:@"move" context:nil];
    //第二步:设置动画的时长
    [UIView setAnimationDuration:3];
    //第三步:设置代理
    [UIView setAnimationDelegate:self];
    //第四步:设置相关的对象的frame
    self.testView.frame = CGRectMake(100, 100, 200, 100);
    //第五步:结束动画
    [UIView commitAnimations];
}
#pragma mark - UIViewAnimationDelegate的代理
//开始动画方法
- (void)animationWillStart:(NSString *)animationID context:(void *)context{
    NSLog(@"ID = %@,context = %@",animationID,context);
}
//结束动画的方法
- (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context{
    NSLog(@"ID = %@,context = %@",animationID,context);
}

改变UIView的颜色

- (IBAction)changeColor:(id)sender {
    [UIView beginAnimations:@"color" context:nil];
    [UIView setAnimationDuration:2];
    [UIView setAnimationDelegate:self];
    self.testView.backgroundColor = [UIColor redColor];
    [UIView commitAnimations];
}

 

改变UIView的透明度

- (IBAction)changeAlpha:(id)sender {
    [UIView beginAnimations:@"alpha" context:nil];
    [UIView setAnimationDuration:5];
    [UIView setAnimationDelegate:self];
    self.testView.alpha = 0.2;
    [UIView commitAnimations];
}

 

UIView的翻转效果

- (IBAction)rotaionAction:(id)sender {
    //开始动画
    [UIView beginAnimations:@"rotation" context:nil];
    //设置时长
    [UIView setAnimationDuration:1.5f];
    //设置淡入的效果
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    //设置代理
    [UIView setAnimationDelegate:self];
    //设置翻转方向
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.testView cache:YES];
    //结束
    [UIView commitAnimations];
    
}

 

UIView的旋转效果

//旋转的效果
- (IBAction)transfromAction:(id)sender {
    [UIView beginAnimations:@"transfrom" context:nil];
    [UIView setAnimationDuration:3.0f];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationRepeatCount:-1];
    //进行旋转,设置旋转角度
    CGAffineTransform transfrom = CGAffineTransformMakeRotation(3*M_PI);
    //设置旋转的角度的对象
    [self.testView setTransform:transfrom];
    [UIView commitAnimations];
    
    
}

CoreAnimation动画

Layer的一些常用属性

 

  //设置图片为圆角
   self.imageview.layer.cornerRadius = self.imageview.frame.size.width/2;
//    //注意:还要设置(masksToBounds这个属性影响layer层的阴影效果)
//    self.imageview.layer.masksToBounds = YES;
    //设置layer的阴影颜色
    self.imageview.layer.shadowColor = [UIColor redColor].CGColor;
    //设置透明度
    self.imageview.layer.shadowOpacity = 0.1;
    //设置阴影的偏移量
    self.imageview.layer.shadowOffset = CGSizeMake(20, 10);
    //设置阴影的模糊度
    self.imageview.layer.shadowRadius = 1.0f;
    
    //需求:拖进来uiview,设置阴影,
    
    self.uiView.layer.shadowColor = [UIColor orangeColor].CGColor;
    self.uiView.layer.shadowOpacity = 0.5;
    self.uiView.layer.shadowOffset = CGSizeMake(30, 30);
    self.uiView.layer.shadowRadius = 2.0f;

 

自定义Layer

- (void)customLayout{
    //创建layer对象
    CALayer *layer = [CALayer layer];
    //设置对象的位置
    layer.frame = CGRectMake(0, 280, 100, 100);
    //设置背景颜色
    layer.backgroundColor = [UIColor redColor].CGColor;
    //设置锚点
    layer.anchorPoint = CGPointMake(0, 0);
    //设置锚点的大小(位置)
    layer.position = CGPointMake(50, 50);
    //layer需要添加到layer层
    [self.view.layer addSublayer:layer];
    
}

CABasicAnimation动画

- (IBAction)basicAnimation:(id)sender {
    
    //第一步:创建动画的对象
    CABasicAnimation *basicAnimation = [CABasicAnimation animation];
    //第二步:告诉layer层,需要执行什么动画,后边设置的内容为CAlay的先关属性
    basicAnimation.keyPath = @"position";
    //第三步:告诉layer哪来,到哪去
    basicAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(100, 100)];
    basicAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(300, 300)];
    //注意:如果要实现移动到的位置不回到原来的位置需要实现以下两句代码;
    basicAnimation.removedOnCompletion = NO;
    //设置保存动画状态的内容
    basicAnimation.fillMode = kCAFillModeForwards;
    //第四步;设置动画持续时长
    basicAnimation.duration = 3.0f;
    //第五步:将要执行的动画添加到calayer上
    [self.imageview.layer addAnimation:basicAnimation forKey:@"basic"];
    
}

CAKeyframeAnimation动画

- (IBAction)keyAction:(id)sender {
    //第一步:创建对象
    CAKeyframeAnimation *keyFrameAnimation = [CAKeyframeAnimation animation];
    //第二步:设置动画轨迹
    keyFrameAnimation.keyPath = @"transform.rotation";
    //第三步:设置翻转角度(弧度的计算公式:度数 / 180 * M_PI)
    keyFrameAnimation.values = @[@(90/180.0*M_PI),@(180/180.0*M_PI),@(360/180.0*M_PI)];
    //第四步;设置动画时长
    keyFrameAnimation.duration = 3.0f;
   //第五步:将要执行的动画添加到layer上
    [self.imageview.layer addAnimation:keyFrameAnimation forKey:@"keyFrameAnimation"];
}

CAAnimationGroupAction组动画

- (IBAction)CAAnimationGroupAction:(id)sender {
    //平移动画
    CABasicAnimation *basicAnimation1 = [CABasicAnimation animation];
    basicAnimation1.keyPath = @"transform.translation.y";
    basicAnimation1.toValue = @(400);
    
    //翻转动画
    CABasicAnimation *basicAnimation2 = [CABasicAnimation animation];
    basicAnimation2.keyPath = @"transform.scale";
    basicAnimation2.toValue = @(3);//弧度
    
    //旋转动画
    CABasicAnimation *basicAnimation3 = [CABasicAnimation animation];
    basicAnimation3.keyPath = @"transform.rotation";
    basicAnimation3.toValue = @(M_PI);
    
    //创建管理动画的动画组
    CAAnimationGroup *group = [CAAnimationGroup animation];
    group.animations = @[basicAnimation1,basicAnimation2,basicAnimation3];
    group.duration = 3.0f;
    [self.imageview.layer addAnimation:group forKey:@"group"];
    
    
 
}

CASpring动画

- (IBAction)CASpringAction:(id)sender {
    //创建对象
    CASpringAnimation *spring = [CASpringAnimation animation];
    spring.keyPath = @"transform.scale";
    spring.fromValue = @1;
    spring.toValue = @0.25;
    spring.duration = 2.0f;
    [self.imageview.layer addAnimation:spring forKey:@"spring"];
}
