iOS 5: programmatically turn bluetooth on and off

I saw that programmatically turning bluetooth on and off was a "private api" thing in previos versions of iOS that would get an app rejected from the apple itunes store.

But in iOS 5, I am aware of previously private things that are no longer private, such as programmatically changing screen brightness. Doing this will no longer get your app rejected in itunes with iOS 5, so I am wondering if this other things were available publicly, like the bluetooth adapter.

CoreBluetooth is publicly available in iOS 5. Unfortunately it only works for new Bluetooth LE (Low Energy) devices.

See CoreBluetooth Documentation

I needed to enable bluetooth programmatically. What I did was use the GKPeerPickerController, this asks you to enable bluetooth if it's not already on. Then on a call for the GKPeerPickerControllerDelegate I dismiss the picker.

Not perfect, you will see the "Searching for devices" for a short time, but It works in lack of another way of doing this (as far as I know).

GKPeerPickerController * peerpicker = [[GKPeerPickerController alloc]init];
peerpicker.delegate = self;
peerpicker.connectionTypesMask = GKPeerPickerConnectionTypeNearby;
[peerpicker show];

When the peerpicker is ready to search there's a delegate method to return a GKSession for the picker to use. This is where you dismiss it.

-(GKSession*)peerPickerController:(GKPeerPickerController *)picker sessionForConnectionType:(GKPeerPickerConnectionType)type
{
    [picker dismiss];
    [picker autorelease];
    return nil;
}

And your app won't get rejected.
