[[UIScreen mainScreen] bounds] 返回的是物理屏幕尺寸而不考虑设备方向。

如果您需要根据当前方向获取屏幕尺寸，请参阅如何获取与方向相关的屏幕高度和宽度？

var PT: CGFloat = 0;

override func viewDidLoad() {

    super.viewDidLoad()
    setPoints();

}

func setPoints() {

    let screenBounds = UIScreen.main.bounds

    let screenScale = UIScreen.main.scale

    let screenSize = CGSize(width: screenBounds.size.width * screenScale, height: screenBounds.size.height * screenScale)

    
    let nativeBounds = UIScreen.main.nativeBounds

    let nativeScale = UIScreen.main.nativeScale

    
    let pxScreenWidth:CGFloat = nativeBounds.width;

    let ptScreenWidth:CGFloat = screenBounds.width;

    PT = pxScreenWidth/ptScreenWidth/nativeScale;

}

使用方法：

let label: UILabel = UILabel(frame: CGRect(x: 15 * PT, y: 10 * PT, width: self.view.frame.width - 30 * PT, height: self.view.frame.height - 20 * PT))
