我试图使工作之前的答复，他们都没有为我工作。所以我为SwiftUI找到了一个解决方案。创建名为UIDevice+Notch.swift的文件

其内容:

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

用法:

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

检查设备型号/机器名称，不要在你的代码中直接使用点/像素计数，这是硬代码，对设备硬件没有意义，设备型号是设备类型匹配的唯一标识符。

#import <sys/utsname.h>

NSString* deviceName()
{
    struct utsname systemInfo;
    uname(&systemInfo);

    return [NSString stringWithCString:systemInfo.machine
                          encoding:NSUTF8StringEncoding];
}

结果:

@"iPhone10,3" on iPhone X (CDMA)
@"iPhone10,6" on iPhone X (GSM)

参考这个答案。

完整的代码实现:

#import <sys/utsname.h>

NSString * GetDeviceModel(void)
{
    static dispatch_once_t onceToken;
    static NSString *strModelID = nil;

    dispatch_once(&onceToken, ^{
#if TARGET_IPHONE_SIMULATOR
        strModelID = NSProcessInfo.processInfo.environment[@"SIMULATOR_MODEL_IDENTIFIER"];
#else
        struct utsname systemInfo;

        uname(&systemInfo);
        strModelID = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
#endif
    });

    return strModelID;
}

// See the `Hardware strings` in https://en.wikipedia.org/wiki/List_of_iOS_devices
BOOL IsiPhoneX(void)
{
    NSString *strModelID = GetDeviceModel();

    return [strModelID isEqualToString:@"iPhone10,3"] || [strModelID isEqualToString:@"iPhone10,6"];
}

BOOL IsNotchiPhone(void)
{
    NSArray<NSString *> *notchiModels = @[
        @"iPhone10,3", @"iPhone10,6", // iPhone X
        @"iPhone11,2", @"iPhone11,4", @"iPhone11,6", // iPhone XS (Max)
        @"iPhone11,8", // iPhone XR
        @"iPhone12,1", @"iPhone12,3", @"iPhone12,5", // iPhone 11 (Pro (Max))
        @"iPhone13,1", @"iPhone13,2", @"iPhone13,3", @"iPhone13,4", // iPhone 12 ([mini]|[Pro (Max)])
    ];

    return [notchiModels containsObject:GetDeviceModel()];
}

随着iOS 12的发布，像iPhone X这样的设备可能会被归入这一类别。

`

extension UIDevice {
    var isPortrait: Bool {

       return UIDeviceOrientationIsPortrait(orientation) ||
      UIInterfaceOrientationIsPortrait(UIApplication.shared.statusBarOrientation)

  }

   var isDeviceWith_XShape : Bool {

    if self.userInterfaceIdiom == .phone {

        if isPortrait
        {
            switch UIScreen.main.nativeBounds.height {

            case 2436,2688,1792:
                print("iPhone X, Xs, Xr, Xs Max")
                return true
            default:
                print("Any other device")
                return false
            }
        }
        else
        {
            switch UIScreen.main.nativeBounds.width {

            case 2436,2688,1792:
                print("iPhone X, Xs, Xr, Xs Max")
                return true
            default:
                print("Any other device")
                return false
            }
        }


    }
    else
    {
        return false
    }

}`

如何检测iOS设备型号和屏幕大小?

CheckDevice检测当前的设备型号和屏幕大小。

你也可以使用

CheckDevice.size () iPhone 12 mini的。screen5_4inch

等等…… 也许……

CheckDevice.isPhone ()

检查设备类型为iPhone。

CheckDevice isWatch()。

CheckDevice isSimulator()。

CheckDevice isPad()。

伟大的回购

检测设备是否为iPhone X的最佳和最简单的方法是，

https://github.com/stephanheilner/UIDevice-DisplayName

var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8 , value != 0 else { return identifier}
            return identifier + String(UnicodeScalar(UInt8(value)))}

标识符是iPhone10,3或者iPhone10,6对于iPhone X。

在看完所有的答案后，我最后是这么做的:

解决方案(兼容Swift 4.1)

extension UIDevice {
    static var isIphoneX: Bool {
        var modelIdentifier = ""
        if isSimulator {
            modelIdentifier = ProcessInfo.processInfo.environment["SIMULATOR_MODEL_IDENTIFIER"] ?? ""
        } else {
            var size = 0
            sysctlbyname("hw.machine", nil, &size, nil, 0)
            var machine = [CChar](repeating: 0, count: size)
            sysctlbyname("hw.machine", &machine, &size, nil, 0)
            modelIdentifier = String(cString: machine)
        }

        return modelIdentifier == "iPhone10,3" || modelIdentifier == "iPhone10,6"
    }

    static var isSimulator: Bool {
        return TARGET_OS_SIMULATOR != 0
    }
}

Use

if UIDevice.isIphoneX {
    // is iPhoneX
} else {
    // is not iPhoneX
}

Note

Pre Swift 4.1你可以检查应用程序是否在模拟器上运行，就像这样:

TARGET_OS_SIMULATOR != 0

从Swift 4.1开始，你可以使用目标环境平台条件检查应用程序是否在模拟器上运行:

#if targetEnvironment(simulator)
    return true
#else
    return false
#endif

(旧的方法仍然有效，但这个新方法更经得起未来的考验)
