关于UI_USER_INTERFACE_IDIOM() & …

使用 UI_USER_INTERFACE_IDIOM() 进行区分
(ios 3.2 >=)
无法区分iphone和ipod

if (UI_USER_INTERFACE_IDIOM()
== UIUserInterfaceIdiomPad)
{

//
<define your constants here>

} else {

//
<define your constants here>

}

区分目前UI_USER_INTERFACE_IDIOM()有2个返回值

UI_USER_INTERFACE_IDIOM()
== UIUserInterfaceIdiomPad

UI_USER_INTERFACE_IDIOM()
== UIUserInterfaceIdiomPhone

使用 UIDevice.model 进行区分
(ios 2.0
>=)

NSString *deviceType
= [UIDevice currentDevice].model;

if([deviceType isEqualToString:@"iPhone"])
{

//iPhone

}

else if([deviceType isEqualToString:@"iPod
touch"]) {

//iPod Touch

}

else {

//iPad

}

使用系统的一个函数sysctlbyname 来获取设备名称

- (NSString *)
platformString

{

size_t size;

sysctlbyname("hw.machine", NULL,
&size, NULL, 0);

char *machine
= malloc(size);

sysctlbyname("hw.machine",
machine, &size, NULL, 0);

NSString *platform
= [NSString stringWithUTF8String:machine];

free(machine);

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:@"iPhone3,3"])
return @"Verizon
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:@"iPod4,1"])
return @"iPod
Touch 4G";

if ([platform isEqualToString:@"iPad1,1"])
return @"iPad";

if ([platform isEqualToString:@"iPad2,1"])
return @"iPad
2 (WiFi)";

if ([platform isEqualToString:@"iPad2,2"])
return @"iPad
2 (GSM)";

if ([platform isEqualToString:@"iPad2,3"])
return @"iPad
2 (CDMA)";

if ([platform isEqualToString:@"i386"])

return @"Simulator";

return @"";

}

在添加一些收集到的

//iPhone

if
([deviceString
isEqualToString:@"iPhone4,1"]) return
@"iPhone 4S";

if
([deviceString
isEqualToString:@"iPhone5,1"]) return
@"iPhone 5(AT&T)";

if
([deviceString
isEqualToString:@"iPhone5,2"]) return
@"iPhone 5(GSM/CDMA)";

//iPod Touch

if
([deviceString
isEqualToString:@"iPod5,1"]) return
@"iPod Touch 5G";

//iPad

if
([deviceString
isEqualToString:@"iPad2,5"]) return
@"iPad Mini (WiFi)";

if
([deviceString
isEqualToString:@"iPad2,6"]) return
@"iPad Mini (GSM)";

if
([deviceString
isEqualToString:@"iPad2,7"]) return
@"iPad Mini (CDMA)";

if
([deviceString
isEqualToString:@"iPad3,1"]) return
@"iPad 3 (WiFi)";

if
([deviceString
isEqualToString:@"iPad3,2"]) return
@"iPad 3 (GSM)";

if
([deviceString
isEqualToString:@"iPad3,3"]) return
@"iPad 3 (CDMA)";

if
([deviceString
isEqualToString:@"iPad3,4"]) return
@"iPad 4 (WiFi)";

if
([deviceString
isEqualToString:@"iPad3,5"]) return
@"iPad 4 (GSM)";

if
([deviceString
isEqualToString:@"iPad3,6"]) return
@"iPad 4 (CDMA)";

//Simulator

if
([deviceString
isEqualToString:@"i386"])
return @"Simulator";

if
([deviceString
isEqualToString:@"x86_64"])
return @"Simulator";

转载的没有那么多个机型逐个实验.所以不敢保证都正确.
