Как анимировать путь CAShapeLayer и fillColor Как оживить путь CAShapeLayer и fillColor? Как оживить strokeEnd, чтобы показать путь, который нарисован? и как оживить fillColor? Ответ 1 Для анимации пути //setup the CAShapeLayer myShapeLayer.strokeColor = [[UIColor blueColor] CGColor]; myShapeLayer.lineWidth = 5; myShapeLayer.fillColor = [[UIColor yellowColor] CGColor]; //Display it! [self.view.layer addSublayer:myShapeLayer]; //Animate path CABasicAnimation *pathAnimation = [CABasicAnimation animationWithKeyPath:@"strokeEnd"]; pathAnimation.duration = 1.5f; pathAnimation.fromValue = [NSNumber numberWithFloat:0.0f]; pathAnimation.toValue = [NSNumber numberWithFloat:1.0f]; pathAnimation.repeatCount = 10; pathAnimation.autoreverses = YES; [myShapeLayer addAnimation:pathAnimation forKey:@"strokeEnd"]; //Animate colorFill CABasicAnimation *fillColorAnimation = [CABasicAnimation animationWithKeyPath:@"fillColor"]; fillColorAnimation.duration = 1.5f; fillColorAnimation.fromValue = (id)[[UIColor clearColor] CGColor]; fillColorAnimation.toValue = (id)[[UIColor yellowColor] CGColor]; fillColorAnimation.repeatCount = 10; fillColorAnimation.autoreverses = YES; [myShapeLayer addAnimation:fillColorAnimation forKey:@"fillColor"]; Надеюсь, это поможет:)
