可以从 UIDevice 的属性 model 得到在现在执行的环境。例子如下:
- NSString *modelname = [[UIDevice currentDevice]model];
- if ([modelname isEqualToString:@"iPhone"]) {
- // iPhone
- }
- if ([modelname isEqualToString:@"IPod Touch"]) {
- // iPod touch
- }
- if ([modelname isEqualToString:@"iPhone Simulator"]) {
- // iPhone Simulator
- }
- 也可以通过宏定义区分
- #if TARGET_OS_IPHONE
- // iPhone Device
- #endif
- #if TARGET_IPHONE_SIMULATOR
- // iPhone Simulator
- #endif
- #if !TARGET_IPHONE_SIMULATOR
- // iPhone Device
- #endif
- ios设备版本的区分-iphone3gs,iphone4....
ios提供了几种c函数来获得相应信息如下
- struct utsname u;
- uname(&u); ///-----get device struct info
- NSString *machine = [NSString stringWithCString:u.machine];
- if ([machine isEqualToString:@"iPhone1,1"]) {
- // iPhone 1G
- }
- if ([machine isEqualToString:@"iPhone1,2"]) {
- // iPhone 3G
- }
- if ([machine isEqualToString:@"iPhone2,1"]) {
- // iPhone 3GS
- }
- if ([machine isEqualToString:@"iPod1,1"]) {
- // iPod touch 1G
- }
- if ([machine isEqualToString:@"iPod2,1"]) {
- // iPod touch 2G
- }
- if ([machine isEqualToString:@"iPod3,1"]) {
- // iPod touch Late2009
- }
- 或者
- - (NSString *) platform
- {
- size_t size;
- sysctlbyname("hw.machine", NULL, &size, NULL, 0);
- char *machine = malloc(size);
- sysctlbyname("hw.machine", machine, &size, NULL, 0);///-----get device struct info
- /*
- Possible values:
- "iPhone1,1" = iPhone 1G
- "iPhone1,2" = iPhone 3G
- "iPhone2,1" = iPhone 3GS
- "iPod1,1" = iPod touch 1G
- "iPod2,1" = iPod touch 2G
- */
- NSString *platform = [NSString stringWithCString:machine];
- free(machine);
- return platform;
- }
