iOS delegate method definition syntax

how do I understand the following syntax:

-(void) centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *) advertisementData:.....

so the method name is didDiscoverPeripheral, why central parameter is defined first?

The method name is centralManager:didDiscoverPeripheral:advertisementData:.

The first parameter tells you which manager discovered the peripheral. You'd otherwise have no idea who was talking to you. It's standard practice with delegate protocols in case you want to talk back.
