Swift3

Question

我有一个按钮，我可以使用以下代码轻松找到它：

let btnRewind = UIButton(
    frame:CGRect(
        x:(UIScreen.main.bounds.size.height/2 - 4*UIScreen.main.bounds.size.height/30),
        y:(UIScreen.main.bounds.size.width/2 - UIScreen.main.bounds.size.height/30),
        width:(UIScreen.main.bounds.size.height/15),
        height:(UIScreen.main.bounds.size.height/15)
    )
)

但相同的代码不适用于我的 UISegmentedControl。那就是 x:0 y:0。我错过了什么：/

var sgmSpeed = UISegmentedControl(
    frame:CGRect(
        x:(UIScreen.main.bounds.size.height/2 - UIScreen.main.bounds.size.height/30),
        y:(UIScreen.main.bounds.size.width/2 - UIScreen.main.bounds.size.height/30),
        width:(UIScreen.main.bounds.size.height/15),
        height:(UIScreen.main.bounds.size.width/15)

    )
)

感谢 Philip Mills

sgmSpeed.frame = CGRect.init(x:(UIScreen.main.bounds.size.height/2 - UIScreen.main.bounds.size.height/6),
                                 y:(UIScreen.main.bounds.size.width/2 + UIScreen.main.bounds.size.height/15),
                                 width:(UIScreen.main.bounds.size.height/3),
                                 height:(UIScreen.main.bounds.size.width/15))

Swift3 - 无法以编程方式定位 UISegmentedControl

Swift3 - cannot locate UISegmentedControl programmatically
