Cancel a call invitation

Cancel an unanswered call invitation with the OpenIM iOS SDK.

Copy

Before an invitation has been answered, the caller can cancel it:

[[OIMManager manager] signalingCancel:signalingInfo
                            onSuccess:^{ [self releaseCallResources]; }
                            onFailure:^(NSInteger code, NSString * _Nullable message) {
    [self showCallError:code message:message ?: @"Failed to cancel the invitation"];
}];

Use the complete OIMSignalingInfo saved when the invitation was initiated. The success callback means that the cancellation signaling request completed. The app should also leave its waiting state and release media resources.
