我正在尝试沿曲线路径设置View动画并同时缩小它:CAKeyframeAnimation*pathAnimation=[CAKeyframeAnimationanimationWithKeyPath:@"position"];pathAnimation.calculationMode=kCAAnimationPaced;pathAnimation.fillMode=kCAFillModeForwards;pathAnimation.removedOnCompletion=NO;//SettingEndpointoftheanimationCGPointendPoint=endCente

例如，我在预自动布局时将其添加到CAAnimationGroup。CABasicAnimation*resizeAnimation=[CABasicAnimationanimationWithKeyPath:@"bounds.size"];[resizeAnimationsetToValue:[NSValuevalueWithCGSize:CGSizeMake(10.0f,10.0f)]];resizeAnimation.fillMode=kCAFillModeForwards;resizeAnimation.removedOnCompletion=NO;在自动布局下，我假设现在我需要
