使用iPhone SDK确定设备（iPhoneiPod Touch）

Posted 2021-02-25

Here is how to determine the device type. How to use it. UIDeviceHardware *h=[[UIDeviceHardware alloc] init]; [self setDeviceModel:[h platformString]]; [h release];

//
//  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
//
//  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:@"iPhone3,1"]) return @"iPhone 4";
    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:@"i386"])   return @"iPhone Simulator";
    return platform;
}
 
@end
