Is it possible to detect Core or system Temperature of iPhone?

is it available in iphone sdk ? if yes could you 开发者_运维技巧show me some example?

Yes, but there's no public API for it (you need IOKit to communicate with the hardwares).

No, it's not available.

It maybe possible if you're using an external accessory or hardware.

Here's the API: http://developer.apple.com/iphone/library/documentation/ExternalAccessory/Reference/EAAccessory_class/Reference/Reference.html
