我相信有更好、更合适的方法来做到这一点。但现在我正在使用 UIScreen.main.bounds 来检测我是否正在处理 iPhone X(812 高)。顺便说一句，这个特定的应用程序仅限横向。这就是我在这个函数中所拥有的，我正在为幻灯片 View 制作幻灯片:
func setupSlideViews(slideView: [SlideView]) {
let screenSize = UIScreen.main.bounds
var frame: CGRect!
if screenSize.width == 812 {
frame = scrollView.frame
} else {
frame = view.frame
}
scrollView.frame = frame
scrollView.contentSize = CGSize(width: frame.width * CGFloat(slideViews.count), height: frame.height)
for (i, slideView) in slideViews.enumerated() {
slideView.frame = CGRect(x: frame.width * CGFloat(i), y: 0, width: frame.width, height: frame.height)
scrollView.addSubview(slideView)
}
}
但是您如何检查模型？
如果您需要检测设备是否为 iPhoneX，请不要使用 bounds，这取决于设备的方向。因此，如果用户以纵向模式打开您的应用程序，它将失败。您可以使用在旋转时不会改变的设备属性 nativeBounds。
In iOS 8 and later, a screen’s bounds property takes the interface
orientation of the screen into account. This behavior means that the
bounds for a device in a portrait orientation may not be the same as
the bounds for the device in a landscape orientation. Apps that rely
on the screen dimensions can use the object in the
fixedCoordinateSpace property as a fixed point of reference for any
calculations they must make. (Prior to iOS 8, a screen’s bounds
rectangle always reflected the screen dimensions relative to a
portrait-up orientation. Rotating the device to a landscape or
upside-down orientation did not change the bounds.)
extension UIDevice {
var iPhoneX: Bool {
return UIScreen.main.nativeBounds.height == 2436
}
}
用法
if UIDevice.current.iPhoneX {
print("This device is a iPhoneX")
}
