提供一个可以获得iOS设备硬件型号的类方法
+ (NSString *)currentMachine {
size_t size; /* sizeof() */
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
// Allocate the space to store name
char *name = (char *)malloc(size);
// Get the platform name
sysctlbyname("hw.machine", name, &size, NULL, 0);
// Place name into a string
NSString *machine = [NSString stringWithUTF8String:name];
// Done with this
free(name);
return machine;
}
//这里的malloc方法返回的是一个void *指针类似于OC中的id类型是一个万能指针可以指代一切，所以在尽可能的时候强转成对应的类型。
void *malloc(size_t);
提供一个可以获得iOS设备准确型号的类方法
注:但是不建议在项目中直接用，如果需要获取展示iOS设备型号的话，传给服务器上面方法获取的型号，让服务器进行匹配返回，客户端无需做任何if判断。
