如何以编程方式检测 iPhone XS 或 iPhone X？

Question

我的一个应用程序连接到网络应用程序服务，该服务向用户提供特定于设备的新闻。为了使其适应最新的 iPhone 版本，我需要以编程方式区分 iPhone XS 和 iPhone X。如何做到这一点？

[[UIScreen mainScreen] bounds].size 始终是区分不同设备的良好起点。但是，iPhone XS 和 iPhone X 具有相同的屏幕尺寸：1125 x 2436。因此在这种情况下使用 [[UIScreen mainScreen] bounds].size 不起作用。

有没有其他方法可以检测最新的 iPhone 版本？

编辑： 这不是问题"How to detected iPhone X"的重复，因为那里讨论的所有answers/solutions都使用屏幕尺寸来指定设备类型。如上所述 iPhone X 和 iPhone XS 具有完全相同的尺寸，因此解决方案无法区分这两个...

Answer 1

我使用 DeviceUtil 来确定 iOS 设备的型号。

根据这个DeviceUtil GitHub post，返回的 UIDevice hardwareString 值为：

iPhone11,2 = iPhone XS
iPhone11,4 = iPhone XS Max
iPhone11,8 = iPhone XR

奇怪的是，Xcode 10 GM 模拟器的 [UIScreen mainScreen]。bounds.size returns 375 x 812 iPhone X、XS、XS Max 和 R 设备.我原以为 XS Max 和 XR 为 414 x 896。

#import <sys/utsname.h> // 在你的头文件或实现文件中导入它。

+(NSString*)deviceName
{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *machineName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];


    NSDictionary *commonNamesDictionary =

      @"iPod5,1":  @"iPod 5th Gen",
      @"iPod7,1":  @"iPod 6th Gen",
      };

    NSString *deviceName = commonNamesDictionary[machineName];

    if (deviceName == nil) {
        deviceName = machineName;
    }

    return deviceName;
}

它将return为您提供的设备型号，还包括 XS、XR、XS Max

您可以使用UIScreen.main.nativeBounds来确定。

 if UIDevice().userInterfaceIdiom == .phone {
        switch UIScreen.main.nativeBounds.height {
        case 1136:
            print("IPHONE 5,5S,5C")
        case 1334:
            print("IPHONE 6,7,8 IPHONE 6S,7S,8S ")
        case 1920, 2208:
            print("IPHONE 6PLUS, 6SPLUS, 7PLUS, 8PLUS")
        case 2436:
            print("IPHONE X, IPHONE XS, IPHONE 11 PRO")
        case 2688:
            print("IPHONE XS MAX, IPHONE 11 PRO MAX")
        case 1792:
            print("IPHONE XR, IPHONE 11")
        default:
            print("UNDETERMINED")
        }
    }

.nativeBounds即使方向改变也不会改变。 https://developer.apple.com/documentation/uikit/uiscreen/1617810-nativebounds
