在iOS中以編程方式將呼叫音頻路由從藍牙耳機更改為iPhone揚聲器

如果藍牙設備已配對，我需要將呼叫音頻路由從藍牙耳機傳輸到iPhone設備，反之亦然。

任何幫助將不勝感激 ？

以下是我用於以編程方式將呼叫音頻路由從藍牙耳機更改為iPhone揚聲器的代碼集

MPAVRoutingController* routingController = [[MPAVRoutingController alloc] init];
[routingController setDiscoveryMode:1];
[routingController fetchAvailableRoutesWithCompletionHandler: ^{
 NSMutableArray* arr = [[NSMutableArray alloc] init];
 for (MPAVRoute* route in [routingController availableRoutes]) {
        [arr addObject:route];
    }

 NSPredicate* predicate = [NSPredicate predicateWithFormat: @"routeUID contains %@", @"Speaker"];

 NSArray* val = [arr filteredArrayUsingPredicate:predicate];
    if ([val count] > 0) {
        [routingController pickRoute:val[0]];
    }
}];
