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");
}

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。”
使用简单的方法检测任何设备。像下面,
func isPhoneDevice() -> Bool {
return UIDevice.current.userInterfaceIdiom == .phone
}
func isDeviceIPad() -> Bool {
return UIDevice.current.userInterfaceIdiom == .pad
}
func isPadProDevice() -> Bool {
let SCREEN_WIDTH: CGFloat = UIScreen.main.bounds.size.width
let SCREEN_HEIGHT: CGFloat = UIScreen.main.bounds.size.height
let SCREEN_MAX_LENGTH: CGFloat = fmax(SCREEN_WIDTH, SCREEN_HEIGHT)
return UIDevice.current.userInterfaceIdiom == .pad && SCREEN_MAX_LENGTH == 1366.0
}
func isPhoneXandXSDevice() -> Bool {
let SCREEN_WIDTH = CGFloat(UIScreen.main.bounds.size.width)
let SCREEN_HEIGHT = CGFloat(UIScreen.main.bounds.size.height)
let SCREEN_MAX_LENGTH: CGFloat = fmax(SCREEN_WIDTH, SCREEN_HEIGHT)
return UIDevice.current.userInterfaceIdiom == .phone && SCREEN_MAX_LENGTH == 812.0
}
func isPhoneXSMaxandXRDevice() -> Bool {
let SCREEN_WIDTH = CGFloat(UIScreen.main.bounds.size.width)
let SCREEN_HEIGHT = CGFloat(UIScreen.main.bounds.size.height)
let SCREEN_MAX_LENGTH: CGFloat = fmax(SCREEN_WIDTH, SCREEN_HEIGHT)
return UIDevice.current.userInterfaceIdiom == .phone && SCREEN_MAX_LENGTH == 896.0
}
像这样叫，
if isPhoneDevice() {
// Your code
}
SWIFT 4/5可重用扩展，支持iPhone 12
extension UIDevice {
enum `Type` {
case iPhone_5_5S_5C_SE1
case iPhone_6_6S_7_8_SE2
case iPhone_6_6S_7_8_PLUS
case iPhone_X_XS_12mini
case iPhone_XR_11
case iPhone_XS_11Pro_Max
case iPhone_12_Pro
case iPhone_12_Pro_Max
}
var hasHomeButton: Bool {
switch type {
case . iPhone_X_XS_12mini, . iPhone_XR_11, .iPhone_XS_11Pro_Max, . iPhone_XS_11Pro_Max, .iPhone_12_Pro, .iPhone_12_Pro_Max:
return false
default:
return true
}
}
var type: Type {
if UI_USER_INTERFACE_IDIOM() == .phone {
switch UIScreen.main.nativeBounds.height {
case 1136:
return .iPhone_5_5S_5C_SE1
case 1334:
return .iPhone_6_6S_7_8_SE2
case 1920, 2208:
return .iPhone_6_6S_7_8_PLUS
case 2436:
return .iPhone_X_XS_12mini
case 2532:
return .iPhone_12_Pro
case 2688:
return .iPhone_XS_11Pro_Max
case 2778:
return .iPhone_12_Pro_Max
case 1792:
return .iPhone_XR_11
default:
assertionFailure("Unknown phone device detected!")
return .iPhone_6_6S_7_8_SE2
}
} else {
assertionFailure("Unknown idiom device detected!")
return .iPhone_6_6S_7_8_SE2
}
}
}
我知道这只是一个快速的解决方案，但它可以帮助一些人。
我在每个项目中都有global .swift，有一些代码来简化我的生活，我总是添加的一件事是ScreenSize和hasNotch，可以轻松检测手机类型和尺寸:
struct ScreenSize {
static let width = UIScreen.main.bounds.size.width
static let height = UIScreen.main.bounds.size.height
}
var hasNotch: Bool {
return UIApplication.shared.delegate?.window??.safeAreaInsets.top ?? 0 > 0
}
然后使用它:
if hasNotch {
print("This executes on all phones with a notch")
}

return UIDevice.current.userInterfaceIdiom == .phone
}
func isDeviceIPad() -> Bool {

func isPadProDevice() -> Bool {
let SCREEN_WIDTH: CGFloat = UIScreen.main.bounds.size.width
let SCREEN_HEIGHT: CGFloat = UIScreen.main.bounds.size.height
let SCREEN_MAX_LENGTH: CGFloat = fmax(SCREEN_WIDTH, SCREEN_HEIGHT)
