Hi! I am developing a TCP application with an iphone as a client and the MAC as a server. I am having a problem with an object of type NSMutableArray where I am getting a warning:
'NSMutableArray may not respond to '-selectedObjects'

My code line is:
NSNetService *remoteService=[[servicesController selectedObjects]lastObject];

Would appreciate some help for this.

NSMutableArray has neither a selectedObjects nor a lastObject method.

Well you're calling selectedObjects on servicesController but servicesController doesn't know that method. What is servicesController declared as? What are you trying to do?

servicesController is an NSArray.It is used to store the names of the servers found on the local network. Actually, in my program the iphone is the client which sends the information to MAC which acts as a server. Both are on a Wifi network

Thanks!

NSArray has no selectedObjects method.

And the rest of that post is more an explanation of what you have and not really what you are trying to do. For example, why do you think you need to call selectedObjects? What is the purpose of that?
