Implicit property animations do not work with CAReplicatorLayer?
The sample code is here.
After replacing explicit property animations with implicit property animations, the animation is broken.
Explicit animation:
-(void)animate:(id)sender {
...
//Transform Animation
animation = [CABasicAnimation animationWithKeyPath:@"transform"];
animation.fromValue = [NSValue valueWithCATransform3D: CATransform3DIdentity];
animation.toValue = [NSValue valueWithCATransform3D: t];
animation.duration = 1.0;
animation.removedOnCompletion = NO;
animation.fillMode = kCAFillModeBoth;
[subLayer addAnimation:animation forKey:@"transform"];
//Opacity Animation
animation = [CABasicAnimation animationWithKeyPath:@"opacity"];
animation.fromValue = [NSNumber numberWithFloat:1.0];
animation.toValue = [NSNumber numberWithFloat:0.0];
animation.duration = 1.0;
animation.removedOnCompletion = NO;
animation.fillMode = kCAFillModeBoth;
[subLayer addAnimation:animation forKey:@"opacity"];
...
}
-(void)reset:(id)sender {
...
//Transform Animation
animation = [CABasicAnimation animationWithKeyPath:@"transform"];
animation.fromValue = [NSValue valueWithCATransform3D: t];
animation.toValue = [NSValue valueWithCATransform3D: CATransform3DIdentity];
animation.duration = 1.0;
animation.removedOnCompletion = NO;
animation.fillMode = kCAFillModeBoth;
[subLayer addAnimation:animation forKey:@"transform"];
//Opacity Animation
animation = [CABasicAnimation animationWithKeyPath:@"opacity"];
animation.fromValue = [NSNumber numberWithFloat:0.0];
animation.toValue = [NSNumber numberWithFloat:1.0];
animation.dur开发者_开发知识库ation = 1.0;
animation.removedOnCompletion = NO;
animation.fillMode = kCAFillModeBoth;
[subLayer addAnimation:animation forKey:@"opacity"];
...
}
Implicit animation:
-(void)animate:(id)sender {
...
//Transform Animation
[CATransaction setAnimationDuration:1];
subLayer.transform = t;
//Opacity Animation
[CATransaction setAnimationDuration:1];
subLayer.opacity = 0;
...
}
-(void)reset:(id)sender {
...
//Transform Animation
[CATransaction setAnimationDuration:1];
subLayer.transform = CATransform3DIdentity;
//Opacity Animation
[CATransaction setAnimationDuration:1];
subLayer.opacity = 1;
...
}
Why?
u don't need to use CATrasaction when you use implicit animation. be carefull that uikit disables the implicit animation of layer which is a root layer of UIView
You should to set CALayer's delegate to something different that view controllers view at an appropriate time (none of nitWithNibName:bundle:, awakeFromNib, viewDidLoad, and viewWillAppear:animated), look here: Does iPhone OS support implicit animation? .
On my machine calling animate on a touch worked very nicely.
