iOS:CABasicAnimation animationWithKeyPath 一些規(guī)定的值

展開全文

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'];

我們可以通過animationWithKeyPath鍵值對(duì)的方式來改變動(dòng)畫
animationWithKeyPath的值：
 
transform.scale = 比例轉(zhuǎn)換
transform.scale.x = 闊的比例轉(zhuǎn)換
transform.scale.y = 高的比例轉(zhuǎn)換
transform.rotation.z = 平面圖的旋轉(zhuǎn)
opacity = 透明度
 
margin
zPosition
 
backgroundColor
 
cornerRadius
borderWidth

 
bounds

cornerRadius
