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:@”iPodtouch”]) {
//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 @”iPhone1G”;
if ([platform isEqualToString:@”iPhone1,2″]) return @”iPhone3G”;
if ([platform isEqualToString:@”iPhone2,1″]) return @”iPhone3GS”;
if ([platform isEqualToString:@”iPhone3,1″]) return @”iPhone4″;
if ([platform isEqualToString:@”iPhone3,3″]) return @”VerizoniPhone 4″;
if ([platform isEqualToString:@”iPod1,1″]) return @”iPodTouch 1G”;
if ([platform isEqualToString:@”iPod2,1″]) return @”iPodTouch 2G”;
if ([platform isEqualToString:@”iPod3,1″]) return @”iPodTouch 3G”;
if ([platform isEqualToString:@”iPod4,1″]) return @”iPodTouch 4G”;
if ([platform isEqualToString:@”iPad1,1″]) return @”iPad”;
if ([platform isEqualToString:@”iPad2,1″]) return @”iPad2 (WiFi)”;
if ([platform isEqualToString:@”iPad2,2″]) return @”iPad2 (GSM)”;
if ([platform isEqualToString:@”iPad2,3″]) return @”iPad2 (CDMA)”;
if ([platform isEqualToString:@”i386″]) return @”Simulator”;
return @””;
