首先获取设备型号 APP版本的操作
// 获取当前App的基本信息字典
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
//app名称
NSString *app_Name = [infoDictionary objectForKey:@"CFBundleDisplayName"];
// app版本
NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
// app build版本
NSString *app_build = [infoDictionary objectForKey:@"CFBundleVersion"];
//手机别名： 用户定义的名称
NSString* userPhoneName = [[UIDevice currentDevice] name];
//设备名称
NSString* deviceName = [[UIDevice currentDevice] systemName];
//手机系统版本
NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
//手机型号
NSString* phoneModel = [[UIDevice currentDevice] model];
//地方型号 （国际化区域名称）
NSString* localPhoneModel = [[UIDevice currentDevice] localizedModel];
下面便是获取手机的型号
从下面开始的方法，都要引用下面这个库（iOS 12 系统还没有更新，不知道iPhone XS、iPhone XS Max、iPhone XR 的机型）
//需要导入头文件：#import <sys/utsname.h>
- (NSString*)iphoneType {
struct utsname systemInfo;
uname(&systemInfo);
NSString*platform = [NSString stringWithCString: systemInfo.machine encoding:NSASCIIStringEncoding];

return platform;
}
下面是获取iPhone手机是否刘海儿屏，方法和上面类似
/**
判断手机是否是异形屏幕
iOS 10 以下 的系统肯定不是刘海儿屏，所以直接iOS10 及以下返回NO，iOS 11 和iOS 12 存在的手机型号很多，这里只要获取手机是不是iPhone X 、iPhone XS、iPhone XS Max、iPhone XR 这几部手机就可以了，剩下的直接返回NO ，这样返回是YES就是曲面屏，（iOS 12 系统还没有更新，不知道iPhone XS、iPhone XS Max、iPhone XR 的代码，所以先写了iPhone X的两个机型）
@return YES 是 异形屏幕
*/
+ (BOOL)iphoneIsProfiledScreen {
float systemValue = [[[UIDevice currentDevice] systemVersion] floatValue];
if ( systemValue >= 11 ) {
struct utsname systemInfo;
uname(&systemInfo);
NSString*platform = [NSString stringWithCString: systemInfo.machine encoding:NSASCIIStringEncoding];
if([platform isEqualToString:@"iPhone10,3"] || [platform isEqualToString:@"iPhone10,6"]) {
return YES;
} else {
return NO;
}
} else {
return NO;
}
}
获取完是不是刘海屏，剩下的自然就是适配刘海屏，刘海屏幕的出现打破以往的适配形式，导航有原来的64变成了88，分栏控制器也发生了变化，所以我们当我知道是否是刘海屏，就知道对应的怎么适配
首先我们要创建三个最常用的宏定义，这两个宏定义分别是自动适配导航的高度，和分栏控制器的距离底部的高度
1、#define SafeAreaTopHeight ([NSObject iphoneIsProfiledScreen] ? 88 : 64)
刘海屏幕返回88，反之返回64，当然这个高度可以更改，看APP需要
2、#define SafeAreaBottomHeight ([NSObject iphoneIsProfiledScreen] ? 34 : 0)
原来距离底部距离为0 的按钮或者其他控件，如果是刘海屏都要向上移动34，为了刘海屏手机底部滑动条的区域留出 ，但是还是看APP需要
3 、#define SafeAreaStatusHeight ([NSObject iphoneIsProfiledScreen] ? 44 : 20)
这个是状态栏的高度
这样就可以用代码适配所有手机型号了
