Как определить, работает ли пользователь приложением на iPhone 4 или 3G/3GS?

Мне нужно определить аппаратное обеспечение, а не версию iOS.

благодарит за любую помощь.

чувствовать себя свободно использовать этот класс - я нашел его here

Использование

UIDeviceHardware *h=[[UIDeviceHardware alloc] init]; 
[self setDeviceModel:[h platformString]]; 
[h release]; 

UIDeviceHardware.h

// 
// UIDeviceHardware.h 
// 
// Used to determine EXACT version of device software is running on. 

#import <Foundation/Foundation.h> 

@interface UIDeviceHardware : NSObject 

- (NSString *) platform; 
- (NSString *) platformString; 

@end 

UIDeviceHardware.m

// 
// UIDeviceHardware.m 
// 
// Used to determine EXACT version of device software is running on. 

#import "UIDeviceHardware.h" 
#include <sys/types.h> 
#include <sys/sysctl.h> 

@implementation UIDeviceHardware 

- (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]; 
    free(machine); 
    return platform; 
} 

- (NSString *) platformString{ 
    NSString *platform = [self platform]; 
    if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 1G"; 
    if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G"; 
    if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS"; 
    if ([platform isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G"; 
    if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G"; 
    if ([platform isEqualToString:@"i386"]) return @"iPhone Simulator"; 
    return platform; 
} 

@end

#import <sys/utsname.h> 

+ (NSString*)deviceModelName { 

     struct utsname systemInfo; 

     uname(&systemInfo); 

     NSString *modelName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; 

     if([modelName isEqualToString:@"i386"]) { 
      modelName = @"iPhone Simulator"; 
     } 
     else if([modelName isEqualToString:@"iPhone1,1"]) { 
      modelName = @"iPhone"; 
     } 
     else if([modelName isEqualToString:@"iPhone1,2"]) { 
      modelName = @"iPhone 3G"; 
     } 
     else if([modelName isEqualToString:@"iPhone2,1"]) { 
      modelName = @"iPhone 3GS"; 
     } 
     else if([modelName isEqualToString:@"iPhone3,1"]) { 
      modelName = @"iPhone 4"; 
     } 
     else if([modelName isEqualToString:@"iPhone4,1"]) { 
      modelName = @"iPhone 4S"; 
     } 
     else if([modelName isEqualToString:@"iPod1,1"]) { 
      modelName = @"iPod 1st Gen"; 
     } 
     else if([modelName isEqualToString:@"iPod2,1"]) { 
      modelName = @"iPod 2nd Gen"; 
     } 
     else if([modelName isEqualToString:@"iPod3,1"]) { 
      modelName = @"iPod 3rd Gen"; 
     } 
     else if([modelName isEqualToString:@"iPad1,1"]) { 
      modelName = @"iPad"; 
     } 
     else if([modelName isEqualToString:@"iPad2,1"]) { 
      modelName = @"iPad 2(WiFi)"; 
     } 
     else if([modelName isEqualToString:@"iPad2,2"]) { 
      modelName = @"iPad 2(GSM)"; 
     } 
     else if([modelName isEqualToString:@"iPad2,3"]) { 
      modelName = @"iPad 2(CDMA)"; 
     } 

     return modelName; 
    }

Вы можете использовать этот код для обнаружения версии ОС для iPhone. float version = [[[UIDevice currentDevice] systemVersion] floatValue];

if (version >= 3.0) { 
    // Only executes on version 3 or above. 
}
