Question

如何检测iPhone X上的运行？我尝试了以下代码。

#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define SCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width)
#define SCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height)
#define SCREEN_MAX_LENGTH (MAX(SCREEN_WIDTH, SCREEN_HEIGHT))
#define IS_IPHONE_X (IS_IPHONE && SCREEN_MAX_LENGTH == 812.0)

当我在iOS模拟器中运行此宏时，IS_IPHONE_X为真。这个宏是否正确？

Answer 1

根据Apple Human Interface Guidelines，iPhone X＆＃39 屏幕宽度= 375，屏幕高度= 812所以，我认为这似乎是正确的！

您可以编写类似

的宏

 #define IS_IPHONE4 (([[UIScreen mainScreen] bounds].size.height-480)?NO:YES)

 #define IS_IPHONE5 (([[UIScreen mainScreen] bounds].size.height-568)?NO:YES)

#define IS_IPHONE6 (([[UIScreen mainScreen] bounds].size.height-667)?NO:YES)

#define IS_IPHONE6P (([[UIScreen mainScreen] bounds].size.height-736)?NO:YES)

 #define IS_IPHONEX (([[UIScreen mainScreen] bounds].size.height-812)?NO:YES)

据我所知，最后一行对你来说应该是一个混乱。但你是对的

#define IS_IPHONE_X (IS_IPHONE && SCREEN_MAX_LENGTH == 812.0)

由于纵向模式下iPhone X的高度为2436px（812pts），横向模式下的宽度为 2436px（812pts）。

正如Lion建议的纵向模式，以下代码适用于两种模式。您只需要更改宏的最后一行

    #define IS_IPHONE_4 (IS_IPHONE && SCREEN_MAX_LENGTH == 480.0)
//iphone 4
    #define IS_IPHONE_5 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)
//iphone 5
    #define IS_IPHONE_6 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)
//iphone 6
    #define IS_IPHONE_6p (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)
//iphone6p
    #define IS_IPHONE_X (IS_IPHONE && SCREEN_MAX_LENGTH == 812.0)
//iphone x

HIII，

希望这对你有所帮助。

目标C

#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_4S (IS_IPHONE && ([[UIScreen mainScreen] bounds].size.height == 480.0) && ((IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale) || !IS_OS_8_OR_LATER))
#define IS_IPHONE_5 (IS_IPHONE && ([[UIScreen mainScreen] bounds].size.height == 568.0) && ((IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale) || !IS_OS_8_OR_LATER))
#define   IS_STANDARD_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0  && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale)
#define IS_ZOOMED_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale > [UIScreen mainScreen].scale)
#define IS_STANDARD_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0)
#define IS_ZOOMED_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale < [UIScreen mainScreen].scale)

您可以在上面的列表中添加更多内容

<强>夫特

let IS_IPAD = (UI_USER_INTERFACE_IDIOM() == .pad)
let IS_IPHONE = (UI_USER_INTERFACE_IDIOM() == .phone)
let IS_IPHONE_4S = (IS_IPHONE && (UIScreen.main.bounds.size.height == 480.0) && ((IS_OS_8_OR_LATER && UIScreen.main.nativeScale == UIScreen.main.scale) || !IS_OS_8_OR_LATER))
let IS_IPHONE_5 = (IS_IPHONE && (UIScreen.main.bounds.size.height == 568.0) && ((IS_OS_8_OR_LATER && UIScreen.main.nativeScale == UIScreen.main.scale) || !IS_OS_8_OR_LATER))
let IS_STANDARD_IPHONE_6 = (IS_IPHONE && UIScreen.main.bounds.size.height == 667.0 && IS_OS_8_OR_LATER && UIScreen.main.nativeScale == UIScreen.main.scale)
let IS_ZOOMED_IPHONE_6 = (IS_IPHONE && UIScreen.main.bounds.size.height == 568.0 && IS_OS_8_OR_LATER && UIScreen.main.nativeScale > UIScreen.main.scale)
let IS_STANDARD_IPHONE_6_PLUS = (IS_IPHONE && UIScreen.main.bounds.size.height == 736.0)

使用此宏，如：

if (IS_IPAD) {
        // your code hear
}

使用宏
