Question

如何检测用户是否在iPhone 4或3G / 3GS上运行应用程序？

我需要检测硬件，而不是iOS版本。

感谢您的帮助。

用法

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;
    }

您可以使用此代码检测iPhone OS版本。 float version = [[[[UIDevice currentDevice] systemVersion] floatValue];

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