Parameters

• proto:

  A protocol.

• other:

  A protocol.

Return Value

Discussion

One protocol can incorporate other protocols using the same syntax that classes use to adopt a protocol:

@protocol ProtocolName < protocol list >

All the protocols listed between angle brackets are considered part of the ProtocolName protocol.
