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
zPositionbackgroundColorcornerRadius
borderWidthbounds
contentscontentsRect
cornerRadius
framehiddenmaskmasksToBounds
opacitypositionshadowColorshadowOffsetshadowOpacity
shadowRadius
