关于UI_USER_INTERFACE_IDIOM() & UIDevice.model

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 @"";

}
