iOS 获取设备型号（最新机型11、11 Pro、11 Pro MAX等）和App版本号等信息 以及获取是否是刘海屏

首先获取设备型号 APP版本的操作   下面便是获取手机的型号

     // 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];

转发一下获取所有机型的代码，从下面开始的方法，都要引用下面这个库（iOS 13 系统更新已经更新很久了，特意填一下获取iPhone 11、iPhone 11 Pro Max、iPhone 11 Pro 的机型）

//需要导入头文件：#import

+ (NSString *)getCurrentDeviceModel{
    struct utsname systemInfo;
    uname(&systemInfo);
    
    NSString *deviceModel = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

接下来给大家附上一个查看所有苹果产品型号的网址，如果出了最新的iPhone新机型，例如iPhone12等，这个网站会第一时间更新，大家在开发过程中就可以获取手机型号

查看网址：https://www.theiphonewiki.com/wiki/Models

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

/**
 判断手机是否是异形屏幕
 
 @return YES 是 异形屏幕
 */
+ (BOOL)iphoneIsProfiledScreen {
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString*platform = [NSString stringWithCString: systemInfo.machine encoding:NSASCIIStringEncoding];
    if([platform isEqualToString:@"iPhone10,3"] || [platform isEqualToString:@"iPhone10,6"]  || [platform isEqualToString:@"iPhone11,8"] || [platform isEqualToString:@"iPhone11,2"] || [platform isEqualToString:@"iPhone11,6"] || [platform isEqualToString:@"iPhone11,4"] || [platform isEqualToString:@"iPhone12,1"] || [platform isEqualToString:@"iPhone12,3"] || [platform isEqualToString:@"iPhone12,5"] ) {
        return YES;
    } 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，这个用的和上面两个用的就很少了

这样就可以用代码适配所有手机型号了，但是用XIB或者storyboard适配不同机型也可以
