Question

I need a way in my app to uniquely identify each device. Is there a method to fetch the ECID of the device?

Answer 1

Will UUID do for you? UUID is unique also. Moreover, I think ECID is not available in all devices (only in the newer hardwares). But, UUID is available in all devices.

UIDevice *device = [UIDevice currentDevice];
NSString *uniqueIdentifier = [device uniqueIdentifier];
