CALayer实现，界限、透明度、位置、旋转、缩放组合动画

首先引入框架：QuartzCore.framework

在头文件声明：CALayer *logoLayer

    //界限
    CABasicAnimation *boundsAnimation = [CABasicAnimation animationWithKeyPath:@"bounds"];
    boundsAnimation.fromValue = [NSValue valueWithCGRect: logoLayer.bounds]; 
    boundsAnimation.toValue = [NSValue valueWithCGRect:CGRectZero];
    
    
    
    //透明度变化
    CABasicAnimation *opacityAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
    opacityAnimation.fromValue = [NSNumber numberWithFloat:1.0];
    opacityAnimation.toValue = [NSNumber numberWithFloat:0.5];
    
    //位置移动
    CABasicAnimation *animation  = [CABasicAnimation animationWithKeyPath:@"position"];
    animation.fromValue =  [NSValue valueWithCGPoint: logoLayer.position];    
    CGPoint toPoint = logoLayer.position;  
    toPoint.x += 180;  
    animation.toValue = [NSValue valueWithCGPoint:toPoint];
    
    //旋转动画
    CABasicAnimation* rotationAnimation =   
    [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];//"z"还可以是“x”“y”，表示沿z轴旋转  
    rotationAnimation.toValue = [NSNumber numberWithFloat:(2 * M_PI) * 3];   
    // 3 is the number of 360 degree rotations   
    // Make the rotation animation duration slightly less than the other animations to give it the feel
    // that it pauses at its largest scale value
    
    rotationAnimation.duration = 2.0f;
    rotationAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; //缓入缓出
    
    
    
    //缩放动画
    CABasicAnimation *scaleAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
    scaleAnimation.fromValue = [NSNumber numberWithFloat:0.0];
    scaleAnimation.toValue = [NSNumber numberWithFloat:1.0];
    scaleAnimation.duration = 2.0f;  
    scaleAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    
    
     //将上述两个动画编组
    CAAnimationGroup *animationGroup = [CAAnimationGroup animation];
    animationGroup.duration = 2.0f;
    animationGroup.autoreverses = YES;   //是否重播，原动画的倒播 
    animationGroup.repeatCount = NSNotFound;//HUGE_VALF;     //HUGE_VALF,源自math.h
    [animationGroup setAnimations:[NSArray arrayWithObjects:rotationAnimation, scaleAnimation, nil]];
    
    [logoLayer addAnimation:animationGroup forKey:@"animationGroup"];
    
    //去掉所有动画
    [logoLayer removeAllAnimations];
    
    //去掉key动画
    [logoLayer removeAnimationForKey:@"animationGroup"];

如何能够到一个动画完成之后运行另一个 CABasicAnimation？(也就是按顺序执行动画)

开始我使用的是下面的方法：添加第二个动画的开始时间；但结果第二个动画没执行。

    CABasicAnimation * appearance =[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
    appearance.duration = 0.5;
    appearance.fromValue = [NSNumber numberWithFloat:0];
    appearance.toValue = [NSNumber numberWithFloat:340];
    appearance.repeatCount = 1;
    appearance.fillMode = kCAFillModeForwards;
    appearance.removedOnCompletion = NO;
    [notif.layer addAnimation:appearance forKey:@"transform.translation.y"];
    
    CABasicAnimation * theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
    theAnimation.duration = 0.5;
    theAnimation.fromValue = [NSNumber numberWithFloat:0];
    theAnimation.toValue = [NSNumber numberWithFloat:10];
    theAnimation.repeatCount = 3;
    theAnimation.autoreverses = YES;
    theAnimation.fillMode = kCAFillModeForwards;
    theAnimation.removedOnCompletion = NO;
    theAnimation.beginTime = appearance.beginTime + appearance.duration;
    [notif.layer addAnimation:theAnimation forKey:@"transform.translation.y"];

这个方法行不通之后我又换了另一个方法：

    CABasicAnimation * appearance =[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
    [appearance setValue:@"animation1" forKey:@"id"];
    appearance.delegate = self;
    [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:)];
    appearance.duration = 0.5;
    appearance.fromValue = [NSNumber numberWithFloat:0];
    appearance.toValue = [NSNumber numberWithFloat:340];
    appearance.repeatCount = 1;
    appearance.fillMode = kCAFillModeForwards;
    appearance.removedOnCompletion = NO;
    [notif.layer addAnimation:appearance forKey:@"transform.translation.y"];

- (void)animationDidStop:(CAAnimation *)theAnimation2 finished:(BOOL)flag {
     if([[theAnimation2 valueForKey:@"id"] isEqual:@"animation1"]) {
         CABasicAnimation * theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
         theAnimation.duration = 0.5;
         theAnimation.fromValue = [NSNumber numberWithFloat:0];
         theAnimation.toValue = [NSNumber numberWithFloat:10];
         theAnimation.repeatCount = 3;
         theAnimation.autoreverses = YES;
         theAnimation.fillMode = kCAFillModeForwards;
         theAnimation.removedOnCompletion = NO;
         theAnimation.beginTime = appearance.beginTime + appearance.duration;
         [notif.layer addAnimation:theAnimation forKey:@"transform.translation.y"];
     }
}
