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 = 比例转换
transform.scale.x = 宽的比例转换
transform.scale.y = 高的比例转换
transform.rotation.z = 平面图的转换
opacity = 透明度 margin
zPosition backgroundColor cornerRadius
borderWidth bounds
contents contentsRect
cornerRadius
frame hidden
mask masksToBounds
opacity position shadowColor shadowOffset shadowOpacity
shadowRadius
