iOS|iOS iPhoneX 适配 iOSiPhoneX适配

一 iPhoneX各个视图值 1.简单定义一下IPoneX

_isIphoneX = [UIScreen mainScreen].bounds.size.height == 812 ? YES : NO;

2.了解IPhoneX各个视图的高度

状态栏 - statusBarHeight
导航栏 - navBarHeight
tabBar
安全距离 - safeAreaBottomHeight

image.png 一般比较常用的说法导航栏高度(状态栏+导航栏)，tabBar高度(tabBar + 安全距离)

1.导航栏高度 88，非iPoneX手机为64
2.状态栏高度44，非iPoneX手机为20
3.tabar高度83，非iPhoneX手机为49

代码如下

AppEnvs.h

@interface AppEnvs : NSObject #pragma mark - 相关变量值 @property(nonatomic, assign) int screenWidth; // 屏幕宽度 @property(nonatomic, assign) int screenHeight; // 屏幕高度 @property(nonatomic, assign) int statusBarHeight; // 系统状态栏高度 @property(nonatomic, assign) int tabBarHeight; // 系统TabBar高度 + 安全距离 @property(nonatomic, assign) int safeAreaBottomHeight; //iPhone X 安全距离 @property(nonatomic, assign) int navBarHeight; // 导航栏高度 @property(nonatomic, assign) int navHeight; // 状态栏 + 导航栏 @property(nonatomic, assign) int screenHeightTabBar; // 屏幕高度 - 状态栏 - 导航栏 - tabBar - 安全距离 @property(nonatomic, assign) int screenHeightTabBarNoNavBar; // 屏高 - 状态栏高度 - tabBar - 安全距离 @property(nonatomic, assign) int screenHeightNoNavBar; // 屏高 - 状态栏 - 导航栏 - 安全距离 @property(nonatomic, assign) int screenHeightNoStatusBar; // 屏幕高度 - 状态栏#pragma mark - 机型 @property(nonatomic, assign) bool isIPhone4; @property(nonatomic, assign) bool isIPhone5; @property(nonatomic, assign) bool isIPhone6; @property(nonatomic, assign) bool isIPhone6Plus; @property(nonatomic, assign) bool isIPhoneBig; @property(nonatomic, assign) bool isIphoneX; @end

AppEnvs.m

@implementation AppEnvs - (instancetype)init { self = [super init]; if (self) { _screenWidth = [UIScreen mainScreen].bounds.size.width; _screenHeight = [UIScreen mainScreen].bounds.size.height; _statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height; _safeAreaBottomHeight = _screenHeight == 812.0 ? 34 : 0; _navBarHeight = 44; _navHeight = _navBarHeight + _statusBarHeight; _tabBarHeight = ([[UIApplication sharedApplication] statusBarFrame].size.height > 20 ? 83 : 49); _screenHeightNoNavBar = _screenHeight - _navHeight - _safeAreaBottomHeight; _screenHeightTabBar = _screenHeight - _navHeight - _tabBarHeight; _screenHeightTabBarNoNavBar = _screenHeight - _statusBarHeight - _tabBarHeight; _screenHeightNoStatusBar = _screenHeight - _statusBarHeight; // 机型 if (_screenHeight == 812) { _isIphoneX = YES; } else if (_screenWidth > 370 && _screenWidth < 400 && _screenHeight != 812) { _isIPhone6 = YES; } else if (_screenWidth > 400 && _screenHeight != 812) { _isIPhone6Plus = YES; } else if (_screenWidth == 320 && _screenHeight == 568) { _isIPhone5 = YES; } else if (_screenWidth == 320 && _screenHeight == 480) { _isIPhone4 = YES; }if (_screenWidth > 370) { _isIPhoneBig = YES; } } return self; } @end

运行结果
