移动UIImages后退{F}

Question

我不知道我是否正确地这样做了。请帮我。我试图在屏幕上来回移动两张图像，使其看起来像是关闭和打开。

while (x>=1) {

    var customFrame1 = Laser1.frame
    if isImageLeftSide {
        customFrame1.origin.x = customFrame1.origin.x + 25
    }
    else {
        customFrame1.origin.x = customFrame1.origin.x - 25
    }

    var customFrame2 = Laser2.frame
    if isImageLeftSide {
        customFrame2.origin.x = customFrame2.origin.x + 25
    }
    else {
        customFrame2.origin.x = customFrame2.origin.x - 25
    }
        x += 1
    }

使用此：

while (x >= 1) {

    UIView.animateWithDuration(YOUR_ANIMATION_DURATION) {

        if isImageLeftSide {
            Laser1.frame.origin.x += 25
        } else {
            Laser1.frame.origin.x -= 25
        }
    }

    UIView.animateWithDuration(YOUR_ANIMATION_DURATION) {

        if isImageLeftSide {
            Laser2.frame.origin.x += 25
        } else {
            Laser2.frame.origin.x -= 25
        }
    }

    x += 1
}

注意：如果Laser1和Laser2是该类的属性，则必须在动画块中使用self.Laser1和self.Laser2。
