Can i check to see if the iPhone is docked?

Question

I wish for my app to act differently when the phone is docked or otherwise connected to the computer. Is this possible?

Answer 1

I couldn't find anything offhand about whether it's docked, but if you look at the UIDevice class you'll find the batteryState property. If you enable battery monitoring in your app, you can check to see if the property is set to UIDeviceBatteryStateUnplugged, implying the device isn't docked. If it's another value (UIDeviceBatteryStateCharging or UIDeviceBatteryStateFull), the phone is connected to power.

Note this doesn't guarantee there's a computer at the other end; it could just as easily be a power adapter into a wall or other USB-powered device.
