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。

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");
其他回答
要识别iPhone 4S，只需检查以下内容:
var isIphone4S: Bool {
let width = UIScreen.main.bounds.size.width
let height = UIScreen.main.bounds.size.height
let proportions = width > height ? width / height : height / width
return proportions == 1.5 && UIDevice.current.model == "iPhone"
}
我在我的应用程序中使用这个。截至2012年12月。

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。
回答在Swift 3，
