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
}
我正在使用Peter Kreinz的代码(因为它是干净的，做了我需要的)，但后来我意识到它只在设备是纵向的时候工作(因为顶部填充将在顶部，显然)
所以我创建了一个扩展来处理所有的方向与它各自的填充，而不依赖于屏幕大小:
extension UIDevice {
var isIphoneX: Bool {
if #available(iOS 11.0, *), isIphone {
if isLandscape {
if let leftPadding = UIApplication.shared.keyWindow?.safeAreaInsets.left, leftPadding > 0 {
return true
}
if let rightPadding = UIApplication.shared.keyWindow?.safeAreaInsets.right, rightPadding > 0 {
return true
}
} else {
if let topPadding = UIApplication.shared.keyWindow?.safeAreaInsets.top, topPadding > 0 {
return true
}
if let bottomPadding = UIApplication.shared.keyWindow?.safeAreaInsets.bottom, bottomPadding > 0 {
return true
}
}
}
return false
}
var isLandscape: Bool {
return UIDeviceOrientationIsLandscape(orientation) || UIInterfaceOrientationIsLandscape(UIApplication.shared.statusBarOrientation)
}
var isPortrait: Bool {
return UIDeviceOrientationIsPortrait(orientation) || UIInterfaceOrientationIsPortrait(UIApplication.shared.statusBarOrientation)
}
var isIphone: Bool {
return self.userInterfaceIdiom == .phone
}
var isIpad: Bool {
return self.userInterfaceIdiom == .pad
}
}
在你的电话网站上
let res = UIDevice.current.isIphoneX
仅在竖屏中，我使用视图框架的宽度和高度来检查:
override func viewDidLoad() {
super.viewDidLoad()
// iPhone Xr: -414 x 896
// iPhone Xs Max: -414 x 896
// iPhone X, Xs: -375 x 812
if view.frame.width == 414 && view.frame.height == 896 || view.frame.width == 375 && view.frame.height == 812 {
print("iPhone X")
} else {
print("not iPhone X")
}
}
竖屏尺寸列在这里
更新
这个答案已经过时了，现在iPhone阵容中有更多的X系列，你要么必须在if-else中列出所有这些尺寸，要么检查设备是否有缺口会更容易。大约1.5年前，我从某个地方得到了这个答案/代码。如果我能链接到代码，我会的。
// 1. add an extension to UIDevice with this computed property
extension UIDevice {
var hasTopNotch: Bool {
if #available(iOS 11.0, tvOS 11.0, *) {
return UIApplication.shared.delegate?.window??.safeAreaInsets.top ?? 0 > 20
}
return false
}
}
// 2. to use in any class
override func viewDidLoad() {
super.viewDidLoad()
if UIDevice.current.hasTopNotch {
print("X series")
} else {
print("regular phone")
}
}
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)
