简介:根据开发工具Xcode10，硬件:苹果放弃4s/5/5c,从se，5s及以上的手机适配;软件:支持iOS8.0及以上系统适配。

一、手机识别
1、硬件编号识别
一款iPhone除了有IPhone XS、XS Max、XR等这样的对外发布手机编号，还有一套对内的iPhone11,2/11,4/11,8等对应的硬件编号

#import <sys/utsname.h>
+ (NSString *)DeviceModel {
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    if ([deviceString isEqualToString:@"iPhone1,1"])    return @"Apple#iPhone 1G";
    if ([deviceString isEqualToString:@"iPhone1,2"])    return @"Apple#iPhone 3G";
    if ([deviceString isEqualToString:@"iPhone2,1"])    return @"Apple#iPhone 3GS";
    if ([deviceString isEqualToString:@"iPhone3,1"])    return @"Apple#iPhone 4";
    if ([deviceString isEqualToString:@"iPhone3,2"])    return @"Apple#iPhone 4 Verizon";
    if ([deviceString isEqualToString:@"iPhone4,1"])    return @"Apple#iPhone 4S";
    if ([deviceString isEqualToString:@"iPhone5,2"])    return @"Apple#iPhone 5";
    if ([deviceString isEqualToString:@"iPhone5,3"])    return @"Apple#iPhone 5c";
    if ([deviceString isEqualToString:@"iPhone5,4"])    return @"Apple#iPhone 5c";
    if ([deviceString isEqualToString:@"iPhone6,1"])    return @"Apple#iPhone 5s";
    if ([deviceString isEqualToString:@"iPhone6,2"])    return @"Apple#iPhone 5s";
    if ([deviceString isEqualToString:@"iPhone7,1"])    return @"Apple#iPhone 6 Plus";
    if ([deviceString isEqualToString:@"iPhone7,2"])    return @"Apple#iPhone 6";
    if ([deviceString isEqualToString:@"iPhone8,1"])    return @"Apple#iPhone 6s";
    if ([deviceString isEqualToString:@"iPhone8,2"])    return @"Apple#iPhone 6s Plus";
    if ([deviceString isEqualToString:@"iPhone8,4"])    return @"Apple#iPhone SE";
    if ([deviceString isEqualToString:@"iPhone9,1"])    return @"Apple#iPhone 7";
    if ([deviceString isEqualToString:@"iPhone9,2"])    return @"Apple#iPhone 7 Plus";
    if ([deviceString isEqualToString:@"iPhone9,3"])    return @"Apple#iPhone 7";
    if ([deviceString isEqualToString:@"iPhone9,4"])    return @"Apple#iPhone 7 Plus";
    if ([deviceString isEqualToString:@"iPhone10,1"])   return @"Apple#iPhone 8 Global";
    if ([deviceString isEqualToString:@"iPhone10,2"])   return @"Apple#iPhone 8 Plus Global";
    if ([deviceString isEqualToString:@"iPhone10,3"])   return @"Apple#iPhone X Global";
    if ([deviceString isEqualToString:@"iPhone10,4"])   return @"Apple#iPhone 8 GSM";
    if ([deviceString isEqualToString:@"iPhone10,5"])   return @"Apple#iPhone 8 Plus GSM";
    if ([deviceString isEqualToString:@"iPhone10,6"])   return @"Apple#iPhone X GSM";

    if ([deviceString isEqualToString:@"iPhone11,2"])   return @"Apple#iPhone XS";
    if ([deviceString isEqualToString:@"iPhone11,4"])   return @"Apple#iPhone XS Max (China)";
    if ([deviceString isEqualToString:@"iPhone11,6"])   return @"Apple#iPhone XS Max";
    if ([deviceString isEqualToString:@"iPhone11,8"])   return @"Apple#iPhone XR";

    if ([deviceString isEqualToString:@"iPhone12,1"])   return @"Apple#iPhone 11";
    if ([deviceString isEqualToString:@"iPhone12,3"])   return @"Apple#iPhone 11 Pro";

    if ([deviceString isEqualToString:@"iPhone12,5"])   return @"Apple#iPhone 11 Pro Max";
    if ([deviceString isEqualToString:@"i386"])         return @"Apple#Simulator 32";
    if ([deviceString isEqualToString:@"x86_64"])       return @"Apple#Simulator 64";

    #ifdef  DEBUG
        NSLog(@"NOTE: Unknown device type: %@", deviceString);
    #endif
     return [NSString stringWithFormat:@"Apple#%@",deviceString];
}

2、屏幕分辨率识别
iPhone 11 Pro Max和iPhone 8 Plus 是App Store审核商店的截图示范机型

二、刘海屏尺寸pt分布

三、实际适配宏定义

/**
 * MARK:-屏幕尺寸宏定义
 * 导航栏高度 状态栏高度 底部tabbar高度 苹果X底部安全区高度
 */
//屏幕rect
#define SCREEN_BOUNDS ([UIScreen mainScreen].bounds)
//屏幕宽度
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
//屏幕高度
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)
//屏幕分辨率
#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))
//iPhone X系列判断
#define  IS_iPhoneX (CGSizeEqualToSize(CGSizeMake(375.f, 812.f), [UIScreen mainScreen].bounds.size) || CGSizeEqualToSize(CGSizeMake(812.f, 375.f), [UIScreen mainScreen].bounds.size)  || CGSizeEqualToSize(CGSizeMake(414.f, 896.f), [UIScreen mainScreen].bounds.size) || CGSizeEqualToSize(CGSizeMake(896.f, 414.f), [UIScreen mainScreen].bounds.size))
//状态栏高度
#define StatusBarHeight (IS_iPhoneX ? 44.f : 20.f)
//导航栏高度
#define NavBarHeight (44.f+StatusBarHeight)
//底部标签栏高度
#define TabBarHeight (IS_iPhoneX ? (49.f+34.f) : 49.f)
//安全区域高度
#define TabbarSafeBottomMargin     (IS_iPhoneX ? 34.f : 0.f)

 //刘海屏除了上面的根据分辨率，还可按底部编剧判断方式 
 //  DYCommTool类:

+ (UIWindow *)o_getKeyWindow;

+ (UIWindow *)o_getKeyWindow {
    if([[[UIApplication sharedApplication] delegate] window]){
        return [[[UIApplication sharedApplication] delegate] window];
    }else {
        if (@available(iOS 13.0,*)) {
            NSArray *arr = [[[UIApplication sharedApplication] connectedScenes] allObjects];
            UIWindowScene *windowScene =  (UIWindowScene *)arr[0];
            UIWindow *mainWindow = [windowScene valueForKeyPath:@"delegate.window"];
            if(mainWindow){
                return mainWindow;
            }else{
                return [UIApplication sharedApplication].windows.lastObject;
            }
        }else {
            return [UIApplication sharedApplication].keyWindow;
        }
    }
}

//获得当前的window
#define KeyWindow [DYCommTool o_getKeyWindow]
// 刘海屏判断 iPhone x系列出场系统是iOS12，刘海屏的系统都是在iOS 11以上的，故可以用KeyWindow.safeAreaInsets判断是否为刘海屏
#define IS_iPhoneX \
( \
 { \
    BOOL iPhoneX = NO; \
    if (@available(iOS 11.0, *)) { \
        if (KeyWindow.safeAreaInsets.bottom > 0) { \
            iPhoneX = YES; \
        } \
    } \
    iPhoneX; \
  }\
)\

四、启动图适配
Assets.xcassets已弃用，推荐使用 LaunchScreen.storyboard 实现

五、app图标适配
