CABasicAnimation animationWithKeyPath Types
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 margin zPosition backgroundColor cornerRadius borderWidth bounds contents contentsRect cornerRadius frame hidden mask masksToBounds opacity position shadowColor shadowOffset shadowOpacity shadowRadius [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];
