是否有方法确定正在运行应用程序的设备。如果可能的话，我想区分iPhone和iPod Touch。
当前回答
我进一步将大的“isEqualToString”块转换为设备类型、生成和逗号后的其他限定符(我称之为子生成)的位掩码分类。它被包装在一个类中，带有一个单例调用SGPlatform，避免了大量重复的字符串操作。代码可用https://github.com/danloughney/spookyGroup
这个类允许你做这样的事情:
if ([SGPlatform iPad] && [SGPlatform generation] > 3) {
// set for high performance
}
and
switch ([SGPlatform deviceMask]) {
case DEVICE_IPHONE:
break;
case DEVICE_IPAD:
break;
case DEVICE_IPAD_MINI:
break;
}
设备的分类在platformBits方法中。这个方法对于本文的读者来说应该非常熟悉。我根据设备的类型和年代对其进行了分类，因为我最感兴趣的是整体性能，但源代码可以调整以提供您感兴趣的任何分类，如视网膜屏幕、网络功能等。

的可能值
[[UIDevice currentDevice] model];
是iPod touch, iPhone, iPhone模拟器，iPad, iPad模拟器
如果你想知道iOS正在破坏哪些硬件，比如iPhone3, iPhone4, iPhone5等，下面是代码
注意:下面的代码可能不包含所有设备的字符串，我和其他人在GitHub上维护相同的代码，所以请从那里获取最新的代码

#include <sys/types.h>
#include <sys/sysctl.h>
- (NSString*)hardwareDescription {
NSString *hardware = [self hardwareString];
if ([hardware isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
if ([hardware isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([hardware isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([hardware isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([hardware isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([hardware isEqualToString:@"iPod1,1"]) return @"iPodTouch 1G";
if ([hardware isEqualToString:@"iPod2,1"]) return @"iPodTouch 2G";
if ([hardware isEqualToString:@"iPad1,1"]) return @"iPad";
if ([hardware isEqualToString:@"iPad2,6"]) return @"iPad Mini";
if ([hardware isEqualToString:@"iPad4,1"]) return @"iPad Air WIFI";
//there are lots of other strings too, checkout the github repo
//link is given at the top of this answer
if ([hardware isEqualToString:@"i386"]) return @"Simulator";

return nil;
}
- (NSString*)hardwareString {
size_t size = 100;
char *hw_machine = malloc(size);
int name[] = {CTL_HW,HW_MACHINE};
sysctl(name, 2, hw_machine, &size, NULL, 0);
NSString *hardware = [NSString stringWithUTF8String:hw_machine];
free(hw_machine);
return hardware;
}
更有用
#include <sys/types.h>
#include <sys/sysctl.h>
@interface UIDevice(Hardware)
- (NSString *) platform;
- (BOOL)hasRetinaDisplay;
- (BOOL)hasMultitasking;
- (BOOL)hasCamera;
@end
@implementation UIDevice(Hardware)
- (NSString *) platform{
int mib[2];
size_t len;
char *machine;
mib[0] = CTL_HW;
mib[1] = HW_MACHINE;
sysctl(mib, 2, NULL, &len, NULL, 0);
machine = malloc(len);
sysctl(mib, 2, machine, &len, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding];
free(machine);
return platform;
}
- (BOOL)hasRetinaDisplay {
NSString *platform = [self platform];
BOOL ret = YES;
if ([platform isEqualToString:@"iPhone1,1"]) {
ret = NO;
}
else
if ([platform isEqualToString:@"iPhone1,2"]) ret = NO;
else
if ([platform isEqualToString:@"iPhone2,1"]) ret = NO;
else
if ([platform isEqualToString:@"iPod1,1"]) ret = NO;
else
if ([platform isEqualToString:@"iPod2,1"]) ret = NO;
else
if ([platform isEqualToString:@"iPod3,1"]) ret = NO;
return ret;
}
- (BOOL)hasMultitasking {
if ([self respondsToSelector:@selector(isMultitaskingSupported)]) {
return [self isMultitaskingSupported];
}
return NO;
}
- (BOOL)hasCamera {
BOOL ret = NO;
// check camera availability
return ret;
}
@end
您可以读取属性
NSLog(@"platform %@, retita %@, multitasking %@", [[UIDevice currentDevice] platform], [[UIDevice currentDevice] hasRetinaDisplay] ? @"YES" : @"NO" , [[UIDevice currentDevice] hasMultitasking] ? @"YES" : @"NO");
请随意使用这个类(gist @ github)

显然，这段代码现在有点过时了，但它肯定可以使用Brian Robbins提供的这个线程上的代码进行更新，其中包括更新模型的类似代码。谢谢你在这个帖子上的支持。
if([UIDevice currentDevice].userInterfaceIdiom==UIUserInterfaceIdiomPad) {
//Device is ipad
}else{
//Device is iphone
}
回答在Swift 3，
struct DeviceInformation {
// UIDevice.current.model's value is "iPhone" or "iPad"，which does not include details; the following "model" is detailed, such as, iPhone7,1 is actually iPhone 6 plus
static let model: String = {
var size = 0
sysctlbyname("hw.machine", nil, &size, nil, 0)
var machine = [CChar](repeating: 0, count: Int(size))
sysctlbyname("hw.machine", &machine, &size, nil, 0)
return String(cString: machine)
}()
static let uuid = UIDevice.current.identifierForVendor?.uuidString ?? ""
static let idForAdService = ASIdentifierManager.shared().advertisingIdentifier.uuidString
