SINCallClient

Objective-C

@protocol SINCallClient <NSObject>

Swift

protocol SINCallClient : NSObjectProtocol

SINCallClient provides the entry point to the calling functionality of the Sinch SDK. A SINCallClient can be acquired via SINClient.

  • Example:

    
id<SINClient> sinchClient;
[sinchClient start];
...

// Place outgoing call.
id<SINCallClient> callClient = [sinchClient callClient];
id<SINCall> call = [callClient callUserWithId:@"<REMOTE USERID>"];

// Set the call delegate that handles all the call state changes
call.delegate= ... ;

// ...

// Hang up the call
[call hangup];

  • The object that acts as the delegate of the call client.

    The delegate object handles call state change events and must adopt the SINCallClientDelegate protocol.
