CABasicAnimation animationWithKeyPath 一些规定的值(Layer层动画)

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

pulse.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];

pulse.autoreverses = YES;

pulse.fromValue = [NSNumber numberWithFloat:.8];

pulse.toValue = [NSNumber numberWithFloat:1.2];
