項(xiàng)目需要用到判斷設(shè)備型號(hào)综苔，于是研究了一下卓囚，把總結(jié)的copy到下面（已更新到se）纺裁。直接上代碼：
// pragma mark 判斷設(shè)備的型號(hào)
+ (NSString *)platformString {
// Gets a string with the device model
size_t size;
int nR = sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = (char *)malloc(size);
nR = sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);
