Question

I’ve created a protocol to manage data source updates.

but invoking methods of the object which implements the protocol won’t work…

I’ve checked if the objects conforms to the protocol with: conformsToProtocol

and the result is no although in the header of the object’s class i’ve declared the protocol:

 @interface MyClass : NSObject <DataSourceProtocol> 
 {
     ...

and implemented the methods…

What could be the problem?

Thanks!

Sounds like you forget to point the DataSourceProtocol to the viewController.

Something like this in viewController:

_tableView.dataSource = self;

I can’t comment the question, so I make above as an answer.
