External Accessory help

[kylej]

So the app I am writing has future potential for a range of accessories. I have no problem getting one accessory connected, but I want to obtain an array of all the accessories I support so I can prompt the user for which accessory they would like to use out of the ones connected. These accessories could be bluetooth or 30-pin.
I have this code, given to me by a manufacturer, that will scan for a device with their protocol string within an array they have created. The strange thing is that they loop through this array, but they only test if an item at index 0 matches their protocol string, unless I am reading it wrong of course. Could someone take a look at the code below and explain to me why they only search for an item at index 0? Is that perhaps reserved for the dock connector?

-(NSArray *) devicesConnected
{
NSMutableArray *devices;
EAAccessoryManager *accessoryManager = [EAAccessoryManager sharedAccessoryManager]; [accessoryManager registerForLocalNotifications];

NSArray *array = [accessoryManager connectedAccessories]; EAAccessory *accessory;

for(accessory in array)
{
if ([[accessory.protocolStrings objectAtIndex:0] isEqualToString:@"com.*******.********"])
{
if (accessory.connected == true)
{
[devices addObject:[accessory.protocolStrings objectAtIndex:0]];
}
}
}
return devices;
}

I believe there is a sample code called "EADemo" in WWDC10 session. That will show you exactly what you need. List of accessory and pick from the list.

Keep in mind, with MFi agreement, you're not allow to show code to public.
