检测设备是否为iPhone X

我的iOS应用程序为UINavigationBar使用了自定义高度，这在新的iPhone X上导致了一些问题。

是否有人已经知道如何通过编程(在Objective-C中)可靠地检测应用程序是否在iPhone X上运行?

编辑:

当然，检查屏幕的大小是可能的，但是，我想知道是否有一些“内置”的方法，如TARGET_OS_IPHONE来检测iOS…

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
    CGSize screenSize = [[UIScreen mainScreen] bounds].size;
    if (screenSize.height == 812)
        NSLog(@"iPhone X");
}

编辑2:

我不认为，我的问题是一个重复的关联问题。当然，有一些方法可以“测量”当前设备的不同属性，并使用结果来决定使用哪种设备。然而，这并不是我在第一篇编辑中试图强调的问题的实际意义。

真正的问题是:“是否有可能直接检测当前设备是否是iPhone X(例如通过某些SDK功能)，还是我必须使用间接测量?”

根据目前给出的答案，我假设答案是“不，没有直接的方法。测量是要走的路。”

当前回答

通常，程序员需要它来约束到顶部或底部，所以这些方法可以提供帮助

static func extraTop() -> CGFloat {

    var top: CGFloat = 0

    if #available(iOS 11.0, *) {

        if let t = UIApplication.shared.keyWindow?.safeAreaInsets.top {
            top = t
        }
    }
    return top
}

static func extraBottom() -> CGFloat {

    var bottom: CGFloat = 0

    if #available(iOS 11.0, *) {

        if let b = UIApplication.shared.keyWindow?.safeAreaInsets.bottom {
            bottom = b
        }
    }
    return bottom
}

在iPhone X之前，这些方法返回:0

iPhone X: 44和34

然后只需将这些额外的内容添加到顶部或底部约束

其他回答

根据@saswanb的回复，这是Swift 4的版本:

var iphoneX = false
if #available(iOS 11.0, *) {
    if ((UIApplication.shared.keyWindow?.safeAreaInsets.top)! > CGFloat(0.0)) {
        iphoneX = true
    }
}

你可以这样做，根据尺寸检测iPhone X设备。

斯威夫特

if UIDevice().userInterfaceIdiom == .phone && UIScreen.main.nativeBounds.height == 2436 {
   //iPhone X
}

目标- C

if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone && UIScreen.mainScreen.nativeBounds.size.height == 2436)  {
  //iPhone X     
}

But,

这是不够的。如果苹果发布的下一代iPhone与iPhone x的尺寸相同，那么最好的方法是使用硬件字符串来检测设备。

对于较新的设备硬件字符串如下。

iPhone 8 - iphone10,1或iPhone 10,4

iPhone 8 Plus - iPhone10,2或iPhone10, 5

iPhone X - iPhone10,3或iPhone10,6

iPhone X, XR, XS, XSMAX, 11 Pro, 11 Pro Max:

注:需实物设备进行测试

参考

 let deviceType = UIDevice.current.modelName
        switch deviceType {
        case "iPhone10,3", "iPhone10,6":
            print("iPhoneX")
        case "iPhone11,2":
            print("iPhone XS")
        case "iPhone11,4":
            print("iPhone XS Max")
        case "iPhone11,6":
            print("iPhone XS Max China")
        case "iPhone11,8":
            print("iPhone XR")
        case "iPhone12,3":
            print("iPhone 11 Pro")
        case "iPhone12,5":
            print("iPhone 11 Pro Max")
        default:
            break
}

extension UIDevice {
    var modelName: String {
        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)))
        }
        return identifier
    }
}

我认为苹果不希望我们手动检查设备是否有“notch”或“home indicator”，但有效的代码是:

-(BOOL)hasTopNotch{

    if (@available(iOS 11.0, *)) {

        float max_safe_area_inset = MAX(MAX([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.top, [[[UIApplication sharedApplication] delegate] window].safeAreaInsets.right),MAX([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.bottom, [[[UIApplication sharedApplication] delegate] window].safeAreaInsets.left));

        return max_safe_area_inset >= 44.0;

    }

    return  NO;

}

-(BOOL)hasHomeIndicator{

    if (@available(iOS 11.0, *)) {

        int iNumberSafeInsetsEqualZero = 0;

        if([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.top == 0.0)iNumberSafeInsetsEqualZero++;
        if([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.right == 0.0)iNumberSafeInsetsEqualZero++;
        if([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.bottom == 0.0)iNumberSafeInsetsEqualZero++;
        if([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.left == 0.0)iNumberSafeInsetsEqualZero++;

        return iNumberSafeInsetsEqualZero <= 2;

    }

    return  NO;

}

其他一些帖子都没用。例如，竖屏模式下“通话状态栏”(绿色栏)的iPhone 6S就有一个很大的顶部安全插件。在我的代码中，所有的情况都被占用(即使设备以纵向或横向启动)
