Disable Warning Dialog if Bluetooth is powered off iOS

Question

My ios application uses bluetooth to connect to an accessory. If Bluetooth is not enabled, a popup appears asking me to activate.

If you are connecting to accessory devices, you might also be using the CBPeripheralManager instead of the CBCentralManager. Tuck me some time to figure this out, because I was using a sdk and couldn't tell what it actually did. But in this case you have to suppress the alert on the peripheral manager. Once the flag is set it will be valid for all other instances of the CBCentralManager or the CBPeripheralManager respectively. Im my case, the only reason I instantiated the CBPeripheralManager at all was to set the flag.

@property CBPeripheralManager *pManager;

*peripheralManager = [[CBPeripheralManager alloc]initWithDelegate:nil queue:nil options:@{CBPeripheralManagerOptionShowPowerAlertKey:@NO}];

Note that you have to assign the instance to a property or it won't work.
