Question

在我的应用中，无框设备（iPhoneX，Xs Xs max，Xr）有一些逻辑。当前，它基于设备的模型工作，因此，我通过DeviceKit框架检测了该模型。

但是我想将此逻辑扩展到未来的无框设备。大概一年后，我们将有一些额外的无框设备。因此，如何检测设备是否无框架？它应该涵盖当前的所有无框设备和将来的无框设备。

我们不能依靠faceID，safeAreaInset，屏幕高度或大小。那又如何呢？

Answer 1

您可以“拟合”最佳状态，例如：

var hasTopNotch: Bool {
    if #available(iOS 11.0, tvOS 11.0, *) {
        return UIApplication.shared.delegate?.window??.safeAreaInsets.top ?? 0 > 20
    }
    return false
}

Answer 2

extension UIDevice {
    var hasNotch: Bool
    {
        if #available(iOS 11.0, *)
        {
            let bottom = UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0
            return bottom > 0
        } else
        {
            // Fallback on earlier versions
            return false
        }
    }
}

使用

if UIDevice.current.hasNotch 
{
    //... consider notch
} 
else 
{
   //... don't have to consider notch
}

自keyWindow was deprecated in iOS 13起，根据从here中找到keyWindow的解决方案开始，这一点对我有效

extension UIDevice {
    var hasNotch: Bool {
        if #available(iOS 11.0, *) {
            let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
            return keyWindow?.safeAreaInsets.bottom ?? 0 > 0
        }
        return false
    }

}

var hasNotch: Bool {
    if #available(iOS 11.0, tvOS 11.0, *) {
        let bottom = UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0
        return bottom > 0
    } else {
        return false
    }
}

Answer 5

支持iOS 5的Swift 5

感谢@Tanin和@DominicMDev，由于keyWindow was deprecated in iOS 13和the iPad Pro has non-zero safeAreaInsets，这对我来说很好。

（已经在iPhone 8，iPhone 11 Pro和iPad Pro (11-inch)(2nd gen)模拟器上进行过测试）

extension UIDevice {
    /// Returns `true` if the device has a notch
    var hasNotch: Bool {
        guard #available(iOS 11.0, *), let window = UIApplication.shared.windows.filter({$0.isKeyWindow}).first else { return false }
        if UIDevice.current.orientation.isPortrait {
            return window.safeAreaInsets.top >= 44
        } else {
            return window.safeAreaInsets.left > 0 || window.safeAreaInsets.right > 0
        }
    }
}

Answer 6

这样，您可以覆盖所有方向：

var hasTopNotch: Bool 
{
    if #available(iOS 11.0,  *) {

        var safeAreaInset: CGFloat?
        if (UIApplication.shared.statusBarOrientation == .portrait) {
            safeAreaInset = UIApplication.shared.delegate?.window??.safeAreaInsets.top
        }
        else if (UIApplication.shared.statusBarOrientation == .landscapeLeft) {
            safeAreaInset = UIApplication.shared.delegate?.window??.safeAreaInsets.left
        }
        else if (UIApplication.shared.statusBarOrientation == .landscapeRight) {
            safeAreaInset = UIApplication.shared.delegate?.window??.safeAreaInsets.right
        }
        return safeAreaInset ?? 0 > 24
    }
    return false
}

Answer 7

这对任何方向均有效。由于iPhone X的最低版本为11.0，因此无需担心11.0之前的iOS版本。 Source

extension UIDevice {

    var hasNotch: Bool {
        if #available(iOS 11.0, *) {
           return UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0 > 0
        }
        return false
   }
}

Answer 8

我这样做是因为iPadPro具有非零的safeAreaInsets。

extension UIDevice {

    /// Returns 'true' if the device has a notch
    var hasNotch: Bool {
        guard #available(iOS 11.0, *), let window = UIApplication.shared.keyWindow else { return false }
        let orientation = UIApplication.shared.statusBarOrientation
        if orientation.isPortrait {
            return window.safeAreaInsets.top >= 44
        } else {
            return window.safeAreaInsets.left > 0 || window.safeAreaInsets.right > 0
        }
    }

}

Answer 9

extension UIDevice {
    var hasNotch: Bool {
        let bottom = UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0
        return bottom > 0
    }
}

使用 'UIDevice.current.hasNotch' 将返回 true 或 false

斯威夫特 5

var hasNotch: Bool {
    let bottom = UIApplication.shared.delegate?.window??.safeAreaInsets.bottom ?? 0
    return bottom > 0
}
