iOS:CABasicAnimation animationWithKeyPath 一些规定的值

When using the ‘CABasicAnimation’ from the QuartzCore Framework in Objective-C, you have to specify an animationWithKeyPath.  This is a long string and is not easily listed in the CABasicAnimation, CAPropertyAnimation, or the CAAnimation class.  I ended up finding a handy chart within the Core Animation Programming guide in Apple’s iPhone OS Reference Library.  Hope this helps save someone time, at least it will for me.

 

 

 

CABasicAnimation *theAnimation;theAnimation=[CABasicAnimation animationWithKeyPath:@'transform.translation.y'];theAnimation.delegate = self;theAnimation.duration = 1;theAnimation.repeatCount = 0;theAnimation.removedOnCompletion = FALSE;theAnimation.fillMode = kCAFillModeForwards;theAnimation.autoreverses = NO;theAnimation.fromValue = [NSNumber numberWithFloat:0];theAnimation.toValue = [NSNumber numberWithFloat:-60]; [self.view.layer addAnimation:theAnimation forKey:@'animateLayer'];

我们可以通过animationWithKeyPath键值对的方式来改变动画animationWithKeyPath的值： transform.scale = 比例轉換transform.scale.x = 闊的比例轉換transform.scale.y = 高的比例轉換transform.rotation.z = 平面圖的旋轉opacity = 透明度 marginzPosition backgroundColor cornerRadiusborderWidth boundscontentscontentsRectcornerRadiusframehiddenmaskmasksToBoundsopacitypositionshadowColorshadowOffsetshadowOpacityshadowRadius[self. ui_View.layer removeAllAnimations];        CABasicAnimation *pulse = [CABasicAnimation animationWithKeyPath:@'transform.scale'];    pulse.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];    pulse.duration = 0.5   (rand() % 10) * 0.05;    pulse.repeatCount = 1;    pulse.autoreverses = YES;    pulse.fromValue = [NSNumber numberWithFloat:.8];    pulse.toValue = [NSNumber numberWithFloat:1.2];    [self.ui_View.layer addAnimation:pulse forKey:nil];// bounds CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@'bounds'];    anim.duration = 1.f;    anim.fromValue = [NSValue valueWithCGRect:CGRectMake(0,0,10,10)];    anim.toValue = [NSValue valueWithCGRect:CGRectMake(10,10,200,200)];    anim.byValue  = [NSValue valueWithCGRect:self. ui_View.bounds]; //    anim.toValue = (id)[UIColor redColor].CGColor;//    anim.fromValue =  (id)[UIColor blackColor].CGColor;        anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    anim.repeatCount = 1;    anim.autoreverses = YES;        [ui_View.layer addAnimation:anim forKey:nil];//cornerRadius     CABasicAnimation *anim2 = [CABasicAnimation animationWithKeyPath:@'cornerRadius'];    anim2.duration = 1.f;    anim2.fromValue = [NSNumber numberWithFloat:0.f];    anim2.toValue = [NSNumber numberWithFloat:20.f];    anim2.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    anim2.repeatCount = CGFLOAT_MAX;    anim2.autoreverses = YES;        [ui_View.layer addAnimation:anim2 forKey:@'cornerRadius'];//contents CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@'contents'];    anim.duration = 1.f;    anim.fromValue = (id)[UIImage imageNamed:@'1.jpg'].CGImage;    anim.toValue = (id)[UIImage imageNamed:@'2.png'].CGImage;//    anim.byValue  = (id)[UIImage imageNamed:@'3.png'].CGImage;//    anim.toValue = (id)[UIColor redColor].CGColor;//    anim.fromValue =  (id)[UIColor blackColor].CGColor;        anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    anim.repeatCount = CGFLOAT_MAX;    anim.autoreverses = YES;        [ui_View.layer addAnimation:anim forKey:nil]; [ui_View.layer setShadowOffset:CGSizeMake(2,2)];    [ui_View.layer setShadowOpacity:1];    [ui_View.layer setShadowColor:[UIColor grayColor].CGColor];//    CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@'shadowColor'];    anim.duration = 1.f;    anim.toValue = (id)[UIColor redColor].CGColor;    anim.fromValue =  (id)[UIColor blackColor].CGColor;        anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    anim.repeatCount = CGFLOAT_MAX;    anim.autoreverses = YES;        [ui_View.layer addAnimation:anim forKey:nil];        CABasicAnimation *_anim = [CABasicAnimation animationWithKeyPath:@'shadowOffset'];    _anim.duration = 1.f;    _anim.fromValue = [NSValue valueWithCGSize:CGSizeMake(0,0)];    _anim.toValue = [NSValue valueWithCGSize:CGSizeMake(3,3)];        _anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    _anim.repeatCount = CGFLOAT_MAX;    _anim.autoreverses = YES;        [ui_View.layer addAnimation:_anim forKey:nil];            CABasicAnimation *_anim1 = [CABasicAnimation animationWithKeyPath:@'shadowOpacity'];    _anim1.duration = 1.f;    _anim1.fromValue = [NSNumber numberWithFloat:0.5];    _anim1.toValue = [NSNumber numberWithFloat:1];        _anim1.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    _anim1.repeatCount = CGFLOAT_MAX;    _anim1.autoreverses = YES;        [ui_View.layer addAnimation:_anim1 forKey:nil];                CABasicAnimation *_anim2 = [CABasicAnimation animationWithKeyPath:@'shadowRadius'];    _anim2.duration = 1.f;    _anim2.fromValue = [NSNumber numberWithFloat:10];    _anim2.toValue = [NSNumber numberWithFloat:5];        _anim2.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];    _anim2.repeatCount = CGFLOAT_MAX;    _anim2.autoreverses = YES;        [ui_View.layer addAnimation:_anim2 forKey:nil];
