Get Device Memory Xcode

I really need to know of 开发者_运维知识库a way to get the current device’s:

1. Active Memory
2. Inactive Memory
3. Wired Memory
4. Free Memory
5. Total Memory

Any information, code or anything is helpful.

Thanks in advance.

The desktop uses the Mach call host_statistics64() to get that information. You can see it in use in the source code for the vm_stat command.
