About IOKit framework in iphone

Thanks in advance. Do any one have idea about IOKit frame work in iphone. Actually i got som开发者_JAVA技巧e information that it was rejected by apple, means if we use this frame work the appstore will not accept the apps. But we can use ambient sensor with IOKit framework. so, any one have an idea about IOKit framework. Please hep me.

It sounds as though the rejection email tells you everything you need to know.

The rule is: you can only use documented APIs.

IOKit is not listed in the iOS documentation. So if you want your app available on the App Store you can't use it. It's as simple as that.
