在 Swift 2 的 animateWithDuration 中设置选项

Setting options in animateWithDuration in Swift 2

我正在使用以下代码为文本字段设置动画:

UIView.animateWithDuration(0.5, delay: 0.4,
        options: .Repeat | .Autoreverse | .CurveEaseOut, animations: {
            self.password.center.x += self.view.bounds.width
        }, completion: nil)

我收到错误 Could not find member 'Repeat'

该代码仅在我只设置一个选项时有效。 为什么不让我设置多个选项?

组合 OptionSetType 的语法已更改,您可以这样操作:

UIView.animateWithDuration(0.5, delay: 0.4,
    options: [.Repeat, .CurveEaseOut, .Autoreverse], animations: {
        self.password.center.x += self.view.bounds.width
    }, completion: nil)
