有没有办法在动画中着色图像？

我知道我可以像这样着色一个图像:

var imageOne:UIImage = UIImage(named: "pullto_1.png")!;
    imageOne = imageOne.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate);
    refSequence.image = imageOne;

但是,当我尝试这样做时,它只是不起作用:

 var imageOne:UIImage = UIImage(named: "pullto_1.png")!;
    imageOne = imageOne.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)

    var image2:UIImage = UIImage(named: "pullto_2.png")!;
    image2 = image2.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)

    var image3:UIImage = UIImage(named: "pullto_3.png")!;
    image3 = image3.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)

    var image4:UIImage = UIImage(named: "pullto_4.png")!;
    image4 = image4.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)

    refSequence.animationImages = NSArray(objects: imageOne,
        image2,
        image3,
        image4

    );

    refSequence.animationDuration = 1.4;
    refSequence.animationRepeatCount = 99;
    refSequence.startAnimating();

难道我做错了什么？有没有办法在动画中着色图像？

谢谢
