android 5阶贝塞尔曲线怎么实现

CGPoint fromPoint = self.imageView.center; //路径曲线 UIBezierPath *movePath = [UIBezierPath bezierPath]; [movePath moveToPoint:fromPoint]; CGPoint toPoint = CGPointMake(300, 460); [movePath addQuadCurveToPoint:toPoint controlPoint:CGPointMake(280,0)]; //关键帧 CAKeyframeAnimation *moveAnim = [CAKeyframeAnimation animationWithKeyPath:@"position"]; moveAnim.path = movePath.CGPath; moveAnim.removedOnCompletion = YES; [self.imageView.layer addAnimation:moveAnim forKey:nil];
