iOS - 3种方法获取设备硬件类型

1.这种是在较高层次获取设备类型，返回的是 iPhone , iPod , iPad 。适合要求不高的。

NSString *deviceType = [[UIDevice currentDevice] model];

2.这是Linux中获取设备类型的方法，主要是C语言的方法，注意引入头文件 #include。输入底层获取设备类型的方法。

#include
- (NSString *)getDeviceVersionInfo
{ 
size_t size; 
// get the length of machine name 
sysctlbyname("hw.machine", NULL, &size, NULL, 0); 
// get machine name 
char *machine = malloc(size); 
sysctlbyname("hw.machine", machine, &size, NULL, 0); 
NSString *platform = [NSString stringWithFormat:@"%s", machine]; free(machine); 

return platform;
}

-(NSString *)correspondVersion
{ 
NSString *correspondVersion = [self getDeviceVersionInfo]; 
if ([correspondVersion isEqualToString:@"i386"]) return@"Simulator"; 
if ([correspondVersion isEqualToString:@"x86_64"]) return@"Simulator"; 
if ([correspondVersion isEqualToString:@"iPhone1,1"]) return@"iPhone 1"; 
if ([correspondVersion isEqualToString:@"iPhone1,2"]) return@"iPhone 3"; 
if ([correspondVersion isEqualToString:@"iPhone2,1"]) return@"iPhone 3S"; 
if ([correspondVersion isEqualToString:@"iPhone3,1"] || [correspondVersion isEqualToString:@"iPhone3,2"]) return@"iPhone 4"; 
if ([correspondVersion isEqualToString:@"iPhone4,1"]) return@"iPhone 4S"; 
if ([correspondVersion isEqualToString:@"iPhone5,1"] || [correspondVersion isEqualToString:@"iPhone5,2"]) return @"iPhone 5"; 
if ([correspondVersion isEqualToString:@"iPhone5,3"] || [correspondVersion isEqualToString:@"iPhone5,4"]) return @"iPhone 5C"; 
if ([correspondVersion isEqualToString:@"iPhone6,1"] || [correspondVersion isEqualToString:@"iPhone6,2"]) return @"iPhone 5S"; if ([correspondVersion isEqualToString:@"iPod1,1"]) return@"iPod Touch 1"; 
if ([correspondVersion isEqualToString:@"iPod2,1"]) return@"iPod Touch 2"; if ([correspondVersion isEqualToString:@"iPod3,1"]) return@"iPod Touch 3"; 
if ([correspondVersion isEqualToString:@"iPod4,1"]) return@"iPod Touch 4"; if ([correspondVersion isEqualToString:@"iPod5,1"]) return@"iPod Touch 5"; if ([correspondVersion isEqualToString:@"iPad1,1"]) return@"iPad 1"; 
if ([correspondVersion isEqualToString:@"iPad2,1"] || [correspondVersion isEqualToString:@"iPad2,2"] || [correspondVersion isEqualToString:@"iPad2,3"] || [correspondVersion isEqualToString:@"iPad2,4"]) return@"iPad 2"; 
if ([correspondVersion isEqualToString:@"iPad2,5"] || [correspondVersion isEqualToString:@"iPad2,6"] || [correspondVersion isEqualToString:@"iPad2,7"] ) return @"iPad Mini"; 
if ([correspondVersion isEqualToString:@"iPad3,1"] || [correspondVersion isEqualToString:@"iPad3,2"] || [correspondVersion isEqualToString:@"iPad3,3"] || [correspondVersion isEqualToString:@"iPad3,4"] || [correspondVersion isEqualToString:@"iPad3,5"] || [correspondVersion isEqualToString:@"iPad3,6"]) return @"iPad 3";

return correspondVersion;
}

3.这是2一样，是Linux中获取设备类型的方法，主要是C语言的方法，注意引入头文件#import "sys/utsname.h"。输入底层获取设备类型的方法。

#import "sys/utsname.h"

- (NSString *)getDeviceVersionInfo
{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *platform = [NSString stringWithFormat:@"%s", systemInfo.machine];
    
    return platform;
}

-(NSString *)correspondVersion
{
    NSString *correspondVersion = [self getDeviceVersionInfo];
    
    if ([correspondVersion isEqualToString:@"i386"])        return@"Simulator";
    if ([correspondVersion isEqualToString:@"x86_64"])       return @"Simulator";
    
    if ([correspondVersion isEqualToString:@"iPhone1,1"])   return@"iPhone 1";
    if ([correspondVersion isEqualToString:@"iPhone1,2"])   return@"iPhone 3";
    if ([correspondVersion isEqualToString:@"iPhone2,1"])   return@"iPhone 3S";
    if ([correspondVersion isEqualToString:@"iPhone3,1"] || [correspondVersion isEqualToString:@"iPhone3,2"])   return@"iPhone 4";
    if ([correspondVersion isEqualToString:@"iPhone4,1"])   return@"iPhone 4S";
    if ([correspondVersion isEqualToString:@"iPhone5,1"] || [correspondVersion isEqualToString:@"iPhone5,2"])   return @"iPhone 5";
    if ([correspondVersion isEqualToString:@"iPhone5,3"] || [correspondVersion isEqualToString:@"iPhone5,4"])   return @"iPhone 5C";
    if ([correspondVersion isEqualToString:@"iPhone6,1"] || [correspondVersion isEqualToString:@"iPhone6,2"])   return @"iPhone 5S";
    
    if ([correspondVersion isEqualToString:@"iPod1,1"])     return@"iPod Touch 1";
    if ([correspondVersion isEqualToString:@"iPod2,1"])     return@"iPod Touch 2";
    if ([correspondVersion isEqualToString:@"iPod3,1"])     return@"iPod Touch 3";
    if ([correspondVersion isEqualToString:@"iPod4,1"])     return@"iPod Touch 4";
    if ([correspondVersion isEqualToString:@"iPod5,1"])     return@"iPod Touch 5";
    
    if ([correspondVersion isEqualToString:@"iPad1,1"])     return@"iPad 1";
    if ([correspondVersion isEqualToString:@"iPad2,1"] || [correspondVersion isEqualToString:@"iPad2,2"] || [correspondVersion isEqualToString:@"iPad2,3"] || [correspondVersion isEqualToString:@"iPad2,4"])     return@"iPad 2";
    if ([correspondVersion isEqualToString:@"iPad2,5"] || [correspondVersion isEqualToString:@"iPad2,6"] || [correspondVersion isEqualToString:@"iPad2,7"] )      return @"iPad Mini";
    if ([correspondVersion isEqualToString:@"iPad3,1"] || [correspondVersion isEqualToString:@"iPad3,2"] || [correspondVersion isEqualToString:@"iPad3,3"] || [correspondVersion isEqualToString:@"iPad3,4"] || [correspondVersion isEqualToString:@"iPad3,5"] || [correspondVersion isEqualToString:@"iPad3,6"])      return @"iPad 3";
    
    return correspondVersion;
