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
我已经创建了一个扩展，让你有3个级别的识别:
设备类型 按英寸划分iPhone/iPad的类型 设备型号
它会随着最新的iOS设备进行更新
UIDeviceDetector
其他回答
我在我的应用程序中使用这个。截至2012年12月。
- (NSString *) platformString {
// Gets a string with the device model
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 encoding:NSUTF8StringEncoding];
free(machine);
if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
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:@"iPhone3,2"]) return @"iPhone 4";
if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4 (CDMA)";
if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5 (GSM+CDMA)";
if ([platform isEqualToString:@"iPod1,1"]) return @"iPod Touch (1 Gen)";
if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch (2 Gen)";
if ([platform isEqualToString:@"iPod3,1"]) return @"iPod Touch (3 Gen)";
if ([platform isEqualToString:@"iPod4,1"]) return @"iPod Touch (4 Gen)";
if ([platform isEqualToString:@"iPod5,1"]) return @"iPod Touch (5 Gen)";
if ([platform isEqualToString:@"iPad1,1"]) return @"iPad";
if ([platform isEqualToString:@"iPad1,2"]) return @"iPad 3G";
if ([platform isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)";
if ([platform isEqualToString:@"iPad2,2"]) return @"iPad 2";
if ([platform isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)";
if ([platform isEqualToString:@"iPad2,4"]) return @"iPad 2";
if ([platform isEqualToString:@"iPad2,5"]) return @"iPad Mini (WiFi)";
if ([platform isEqualToString:@"iPad2,6"]) return @"iPad Mini";
if ([platform isEqualToString:@"iPad2,7"]) return @"iPad Mini (GSM+CDMA)";
if ([platform isEqualToString:@"iPad3,1"]) return @"iPad 3 (WiFi)";
if ([platform isEqualToString:@"iPad3,2"]) return @"iPad 3 (GSM+CDMA)";
if ([platform isEqualToString:@"iPad3,3"]) return @"iPad 3";
if ([platform isEqualToString:@"iPad3,4"]) return @"iPad 4 (WiFi)";
if ([platform isEqualToString:@"iPad3,5"]) return @"iPad 4";
if ([platform isEqualToString:@"iPad3,6"]) return @"iPad 4 (GSM+CDMA)";
if ([platform isEqualToString:@"i386"]) return @"Simulator";
if ([platform isEqualToString:@"x86_64"]) return @"Simulator";
return platform;
}
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");
这是UIDeviceHardware的更新。M来自上面的答案。

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

我知道答案已经被勾选了，但为了将来的参考，你可以总是使用设备屏幕大小来找出它是哪台设备:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
CGSize result = [[UIScreen mainScreen] bounds].size;
if (result.height == 480) {
// 3.5 inch display - iPhone 4S and below
NSLog(@"Device is an iPhone 4S or below");
}
else if (result.height == 568) {
// 4 inch display - iPhone 5
NSLog(@"Device is an iPhone 5/S/C");
}
else if (result.height == 667) {
// 4.7 inch display - iPhone 6
NSLog(@"Device is an iPhone 6");
}
else if (result.height == 736) {
// 5.5 inch display - iPhone 6 Plus
NSLog(@"Device is an iPhone 6 Plus");
}
}
else if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
// iPad 9.7 or 7.9 inch display.
NSLog(@"Device is an iPad.");
}
