iOS 获取设备型号和App版本号等信息 以及获取是否是刘海屏

2019-01-17  本文已影响1人  丿尛峯

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];

if([platform isEqualToString:@"iPhone1,1"])  return@"iPhone 2G";

if([platform isEqualToString:@"iPhone1,2"])  return@"iPhone 3G";

if([platform isEqualToString:@"iPhone2,1"])  return@"iPhone 3GS";

if([platform isEqualToString:@"iPhone3,1"])  return@"iPhone 4";

if([platform isEqualToString:@"iPhone3,2"])  return@"iPhone 4";

if([platform isEqualToString:@"iPhone3,3"])  return@"iPhone 4";

if([platform isEqualToString:@"iPhone4,1"])  return@"iPhone 4S";

if([platform isEqualToString:@"iPhone5,1"])  return@"iPhone 5";

if([platform isEqualToString:@"iPhone5,2"])  return@"iPhone 5";

if([platform isEqualToString:@"iPhone5,3"])  return@"iPhone 5c";

if([platform isEqualToString:@"iPhone5,4"])  return@"iPhone 5c";

if([platform isEqualToString:@"iPhone6,1"])  return@"iPhone 5s";

if([platform isEqualToString:@"iPhone6,2"])  return@"iPhone 5s";

if([platform isEqualToString:@"iPhone7,1"])  return@"iPhone 6 Plus";

if([platform isEqualToString:@"iPhone7,2"])  return@"iPhone 6";

if([platform isEqualToString:@"iPhone8,1"])  return@"iPhone 6s";

if([platform isEqualToString:@"iPhone8,2"])  return@"iPhone 6s Plus";

if([platform isEqualToString:@"iPhone8,4"])  return@"iPhone SE";

if([platform isEqualToString:@"iPhone9,1"])  return@"iPhone 7";

if([platform isEqualToString:@"iPhone9,2"])  return@"iPhone 7 Plus";

if([platform isEqualToString:@"iPhone10,1"]) return@"iPhone 8";

if([platform isEqualToString:@"iPhone10,4"]) return@"iPhone 8";

if([platform isEqualToString:@"iPhone10,2"]) return@"iPhone 8 Plus";

if([platform isEqualToString:@"iPhone10,5"]) return@"iPhone 8 Plus";

if([platform isEqualToString:@"iPhone10,3"]) return@"iPhone X";

if([platform isEqualToString:@"iPhone10,6"]) return@"iPhone X";

if([platform isEqualToString:@"iPod1,1"])  return@"iPod Touch 1G";

if([platform isEqualToString:@"iPod2,1"])  return@"iPod Touch 2G";

if([platform isEqualToString:@"iPod3,1"])  return@"iPod Touch 3G";

if([platform isEqualToString:@"iPod4,1"])  return@"iPod Touch 4G";

if([platform isEqualToString:@"iPod5,1"])  return@"iPod Touch 5G";

if([platform isEqualToString:@"iPad1,1"])  return@"iPad 1G";

if([platform isEqualToString:@"iPad2,1"])  return@"iPad 2";

if([platform isEqualToString:@"iPad2,2"])  return@"iPad 2";

if([platform isEqualToString:@"iPad2,3"])  return@"iPad 2";

if([platform isEqualToString:@"iPad2,4"])  return@"iPad 2";

if([platform isEqualToString:@"iPad2,5"])  return@"iPad Mini 1G";

if([platform isEqualToString:@"iPad2,6"])  return@"iPad Mini 1G";

if([platform isEqualToString:@"iPad2,7"])  return@"iPad Mini 1G";

if([platform isEqualToString:@"iPad3,1"])  return@"iPad 3";

if([platform isEqualToString:@"iPad3,2"])  return@"iPad 3";

if([platform isEqualToString:@"iPad3,3"])  return@"iPad 3";

if([platform isEqualToString:@"iPad3,4"])  return@"iPad 4";

if([platform isEqualToString:@"iPad3,5"])  return@"iPad 4";

if([platform isEqualToString:@"iPad3,6"])  return@"iPad 4";

if([platform isEqualToString:@"iPad4,1"])  return@"iPad Air";

if([platform isEqualToString:@"iPad4,2"])  return@"iPad Air";

if([platform isEqualToString:@"iPad4,3"])  return@"iPad Air";

if([platform isEqualToString:@"iPad4,4"])  return@"iPad Mini 2G";

if([platform isEqualToString:@"iPad4,5"])  return@"iPad Mini 2G";

if([platform isEqualToString:@"iPad4,6"])  return@"iPad Mini 2G";

if([platform isEqualToString:@"iPad4,7"])  return@"iPad Mini 3";

if([platform isEqualToString:@"iPad4,8"])  return@"iPad Mini 3";

if([platform isEqualToString:@"iPad4,9"])  return@"iPad Mini 3";

if([platform isEqualToString:@"iPad5,1"])  return@"iPad Mini 4";

if([platform isEqualToString:@"iPad5,2"])  return@"iPad Mini 4";

if([platform isEqualToString:@"iPad5,3"])  return@"iPad Air 2";

if([platform isEqualToString:@"iPad5,4"])  return@"iPad Air 2";

if([platform isEqualToString:@"iPad6,3"])  return@"iPad Pro 9.7";

if([platform isEqualToString:@"iPad6,4"])  return@"iPad Pro 9.7";

if([platform isEqualToString:@"iPad6,7"])  return@"iPad Pro 12.9";

if([platform isEqualToString:@"iPad6,8"])  return@"iPad Pro 12.9";

if([platform isEqualToString:@"i386"])  return@"iPhone Simulator";

if([platform isEqualToString:@"x86_64"])  return@"iPhone Simulator";

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
