如何判断 ios设备的类型（iphone，ipod，ipad）

用下面的功能函数就可以： + (NSString*)getDeviceVersion { size_t size; sysctlbyname("hw.machine", NULL, &size, NULL, 0); char *machine = (char*)malloc(size); sysctlbyname("hw.machine", machine, &size, NULL, 0); NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding]; free(machine); return platform; }输出： //@"iPad1,1" //@"iPad2,1" //@"i386" 逗号后面数字解释：(i386是指模拟器) 1-WiFi版 2-GSM/WCDMA 3G版 3-CDMA版 AppleTV(2G) (AppleTV2,1) iPad (iPad1,1) iPad2,1 (iPad2,1)Wifi版 iPad2,2 (iPad2,2)GSM3G版 iPad2,3 (iPad2,3)CDMA3G版 iPhone (iPhone1,1) iPhone3G (iPhone1,2) iPhone3GS (iPhone2,1) iPhone4 (iPhone3,1) iPhone4(vz) (iPhone3,3)iPhone4 CDMA版 iPhone4S (iPhone4,1) iPodTouch(1G) (iPod1,1) iPodTouch(2G) (iPod2,1) iPodTouch(3G) (iPod3,1) iPodTouch(4G) (iPod4,1) 另外放两个固件下载地址： /ios/ /ios/ 判断ipad/iphone UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ?或者 [[[UIDevice currentDevice] model] isEqualToString:@"iPad"]; ?判断设备是否有摄像头 [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]; ?
