方法1：
//判断是否为iPhone X
#define IPHONE_X ({BOOL isPhoneX = NO;if (@available(iOS 11.0, *)) {isPhoneX = [[UIApplication sharedApplication] delegate].window.safeAreaInsets.bottom > 0.0;}(isPhoneX);})
//系统导航栏总高度 #define bAllNavTotalHeight (IPHONE_X ? 88 : 64) // 底部安全区域远离高度 现在使用 #define kBottomSafeHeight (IPHONE_X?(34):(0)) //状态栏高度 #define STATUSBAR_HEIGHT (IPHONE_X ? 44 : 20)
方法2：
/** 系统高度，宽度 bounds */ #define SCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width) #define SCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height) //是否刘海屏 #define kDevice_Is_iPhoneXScreen (SCREEN_HEIGHT == 812.0f || SCREEN_HEIGHT == 896.0f || SCREEN_HEIGHT == 844.0f || SCREEN_HEIGHT == 926.0f || SCREEN_HEIGHT == 780.0f)
方法3:
#define TopStatuHeight [[UIApplication sharedApplication] statusBarFrame].size.height //系统底部TabBar高度 #define bTabBarHeight (TopStatuHeight>20?83:49) //系统导航栏总高度 #define bAllNavTotalHeight (TopStatuHeight>20?88:64) // 底部安全区域远离高度 #define kBottomSafeHeight (TopStatuHeight>20?34:0)
