用宏检测 iPhone X

Question

如何在 iPhone X 上检测运行ning？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模拟器中运行这个宏时，那么IS_IPHONE_X为真。这个宏正确吗？

Answer 1

最后一行，据我所知应该是你的困惑。但你是对的

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

因为 iPhone X 在纵向模式下的高度是 2436px(812pts)，在横向模式下的宽度是 2436px (812pts).

正如 Lion 建议的人像模式，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

Answer 2

根据 Apple Human Interface Guidelines、iPhone X 的说法 screen width = 375 and screen height = 812 所以，我认为这似乎是正确的！

您可以编写类似这样的宏，

 #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)

嗨，

希望对您有所帮助。

Objective 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

Swift

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)

像这样使用这个宏：

if (IS_IPAD) {
        // your code hear
}
