分享iPhone判断程序运行设备的代码

判断你的程序是否运行在iPhone还是iPad上

BOOL deviceIsPad() { 
#ifdef __IPHONE_3_2 
return UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad; 
#else 
return NO; 
#endif 
} 

用下面这种方式判断当前使用的是哪个固件版本的硬件。。

#import "UIDeviceHardware.h" 
#include 
#include 

@implementation UIDeviceHardware 

- (NSString *) platform{ 
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]; 
free(machine); 
return platform; 
} 

- (NSString *) platformString{ 
NSString *platform = [self platform]; 
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:@"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:@"i386"]) return @"iPhone Simulator"; 
return platform; 
}
