问题
My question is very similar to this one: iPhone Proximity Sensor. There's clearly some manner of thermometer within the iPhone that's readable by the OS. Has anyone uncovered the super-secret undocumented APIs to read this sensor?
回答1:
I doubt this sensor is for ambient temperature - rather I suspect it is for overheating of the circuits. If that is all you want then great, but again, I think it would be useless for ambient temperature.
just my opinion.
回答2:
All i could find was CTGetTemperature in CoreTelephony of all places.
回答3:
I don't know about previous models, but my iPhone4 goes from cool-ish to very warm in a matter of minutes depending on the various radio usages. So unless "good enough" = "within 20 degrees F or so", then probably not good for ambient measurement.
Unless (maybe you meant this) you could also track radio usage and subtract a temperature variable depending on radio usages. phew. complicated. Easier to just query NWS.
回答4:
command to get all super-secret names which related with temperature in CoreTelephony framework
nm "/Applications/Xcode463.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/6.1 (10B141)/Symbols/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony" | grep empera
