检测特定的iPhone / iPod touch的模型[复制]

Question

  

<强>可能重复：结果   确定装置（iPhone，iPod Touch的）与iOS

我在做一个游戏，利用iPhone的对等网络蓝牙功能（也可能是iPod touch的第二代）。然而，从试图播放iPod上的第一代和iPhone 2G多人，我需要检查的具体设备型号停止用户使用。

[[的UIDevice currentDevice]模型]将只告诉我，如果该设备是一个 “iPhone” 或 “iPod touch的”。有没有办法检查特定的设备型号，如：“iPhone 3GS”，“iPod touch的第一代”什么的。

有是的UIDevice类别（我认为这是由埃里卡丧盾创建，我并不把它的信用），使用下面的代码来获取特定设备型号。你可以在这里找到品类全，以及其他有用的东西： https://github.com/erica/uidevice -extension

#include <sys/types.h>
#include <sys/sysctl.h>

@implementation UIDevice (Hardware)

/*
 Platforms
 iPhone1,1 -> iPhone 1G
 iPhone1,2 -> iPhone 3G 
 iPod1,1   -> iPod touch 1G 
 iPod2,1   -> iPod touch 2G 
*/

- (NSString *) platform
{
  size_t size;
  sysctlbyname("hw.machine", NULL, &size, NULL, 0);
  char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
  free(machine);
  return platform;
}

这工作，并使用该应用程序已在AppStore最近一直认可。

Answer 1

最完整的UIDevice（硬件）类别可能是 http://github.com/erica/uidevice-延伸/ （埃丽卡丧盾）：

[[UIDevice currentDevice] platformType]   // ex: UIDevice4GiPhone
[[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"

Answer 2

您可以使用uname从sys/utsname.h获得设备型号。例如：

#import <sys/utsname.h>

NSString*
machineName()
{
    struct utsname systemInfo;
    uname(&systemInfo);

    return [NSString stringWithCString:systemInfo.machine
                              encoding:NSUTF8StringEncoding];
}

结果应该是：

@"i386"      on the simulator
@"iPod1,1"   on iPod Touch
@"iPod2,1"   on iPod Touch Second Generation
@"iPod3,1"   on iPod Touch Third Generation
@"iPod4,1"   on iPod Touch Fourth Generation
@"iPhone1,1" on iPhone
@"iPhone1,2" on iPhone 3G
@"iPhone2,1" on iPhone 3GS
@"iPad1,1"   on iPad
@"iPad2,1"   on iPad 2
@"iPad3,1"   on iPad 3 (aka new iPad)
@"iPhone3,1" on iPhone 4
@"iPhone4,1" on iPhone 4S
@"iPhone5,1" on iPhone 5
@"iPhone5,2" on iPhone 5

这个怎么样的代码，如果新版本发布之后，您将与最后一个已知设备标识符

#include <sys/types.h>
#include <sys/sysctl.h>

- (NSString *)getModel {
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *model = malloc(size);
    sysctlbyname("hw.machine", model, &size, NULL, 0);
    NSString *sDeviceModel = [NSString stringWithCString:model encoding:NSUTF8StringEncoding];
    free(model);                              
    if ([sDeviceModel isEqual:@"i386"])      return @"Simulator";  //iPhone Simulator
    if ([sDeviceModel isEqual:@"iPhone1,1"]) return @"iPhone1G";   //iPhone 1G
    if ([sDeviceModel isEqual:@"iPhone1,2"]) return @"iPhone3G";   //iPhone 3G
    if ([sDeviceModel isEqual:@"iPhone2,1"]) return @"iPhone3GS";  //iPhone 3GS
    if ([sDeviceModel isEqual:@"iPhone3,1"]) return @"iPhone4 AT&T";  //iPhone 4 - AT&T
    if ([sDeviceModel isEqual:@"iPhone3,2"]) return @"iPhone4 Other";  //iPhone 4 - Other carrier
    if ([sDeviceModel isEqual:@"iPhone3,3"]) return @"iPhone4";    //iPhone 4 - Other carrier
    if ([sDeviceModel isEqual:@"iPhone4,1"]) return @"iPhone4S";   //iPhone 4S
    if ([sDeviceModel isEqual:@"iPhone5,1"]) return @"iPhone5";    //iPhone 5 (GSM)
    if ([sDeviceModel isEqual:@"iPod1,1"])   return @"iPod1stGen"; //iPod Touch 1G
    if ([sDeviceModel isEqual:@"iPod2,1"])   return @"iPod2ndGen"; //iPod Touch 2G
    if ([sDeviceModel isEqual:@"iPod3,1"])   return @"iPod3rdGen"; //iPod Touch 3G
    if ([sDeviceModel isEqual:@"iPod4,1"])   return @"iPod4thGen"; //iPod Touch 4G
    if ([sDeviceModel isEqual:@"iPad1,1"])   return @"iPadWiFi";   //iPad Wifi
    if ([sDeviceModel isEqual:@"iPad1,2"])   return @"iPad3G";     //iPad 3G
    if ([sDeviceModel isEqual:@"iPad2,1"])   return @"iPad2";      //iPad 2 (WiFi)
    if ([sDeviceModel isEqual:@"iPad2,2"])   return @"iPad2";      //iPad 2 (GSM)
    if ([sDeviceModel isEqual:@"iPad2,3"])   return @"iPad2";      //iPad 2 (CDMA)

    NSString *aux = [[sDeviceModel componentsSeparatedByString:@","] objectAtIndex:0];

//If a newer version exist
    if ([aux rangeOfString:@"iPhone"].location!=NSNotFound) {
        int version = [[aux stringByReplacingOccurrencesOfString:@"iPhone" withString:@""] intValue];
        if (version == 3) return @"iPhone4"
        if (version >= 4) return @"iPhone4s";

    }
    if ([aux rangeOfString:@"iPod"].location!=NSNotFound) {
        int version = [[aux stringByReplacingOccurrencesOfString:@"iPod" withString:@""] intValue];
        if (version >=4) return @"iPod4thGen";
    }
    if ([aux rangeOfString:@"iPad"].location!=NSNotFound) {
        int version = [[aux stringByReplacingOccurrencesOfString:@"iPad" withString:@""] intValue];
        if (version ==1) return @"iPad3G";
        if (version >=2) return @"iPad2";
    }
    //If none was found, send the original string
    return sDeviceModel;
}

Answer 4

BOOL hasHighResScreen = NO;
if ([UIScreen instancesRespondToSelector:@selector(scale)]) {
    CGFloat scale = [[UIScreen mainScreen] scale];
    if (scale > 1.0) {
        hasHighResScreen = YES;
    }
}

Answer 5

iPhone 4是iPhone3,1和iPhone3,2结果 iPhone 4S是iPhone4,1结果 iPad 2的是iPad2,1 iPad2,2并且取决于版本iPad2,3（GSM等），点击 ipad公司3是iPad3,1 iPad3,2并且取决于版本iPad3,3（GSM等）的结果，

Answer 6

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

和然后检查如果字符串是等于任何设备你正在寻找这样的：

if(value==@"iPod1,1" ) 
{}

和你应该是好去。
