CABasicAnimation animationWithKeyPath 一些规定的值

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
