| - (BOOL) showBluetoothPowerAlert |
|
readwritenonatomicassign |
Mostra o alerta do sistema quando o Bluetooth está desativado. O padrão é YES.
| - (GNSErrorStateHandler) microphonePermissionErrorHandler |
|
readwritenonatomiccopy |
Os seguintes gerenciadores de erros são chamados (na linha de execução principal) quando o status do erro muda.
Um valor YES implica um erro. A permissão de acesso ao microfone foi negada.
| - (GNSErrorStateHandler) bluetoothPermissionErrorHandler |
|
readwritenonatomiccopy |
Permissão de Bluetooth negada.
| - (GNSErrorStateHandler) bluetoothPowerErrorHandler |
|
readwritenonatomiccopy |
O Bluetooth está desligado.
| - (BOOL) useBestAudioSessionCategory |
|
readwritenonatomicassign |
Esse parâmetro só é relevante se o app usa a mídia de áudio para a descoberta.
Quando definida como YES, o Nearby definirá a categoria e as opções de AVAudioSession como os valores que funcionam melhor para Nearby: AVAudioSessionCategoryPlayAndRecord e AVAudioSessionCategoryOptionDefaultToSpeaker, respectivamente. Se você defini-la como NO, a categoria e as opções atuais serão preservadas e usadas pelo Nearby. Isso pode resultar na impossibilidade de o Nearby transmitir ou gravar áudio. Por exemplo, se o app usa AVAudioSessionCategoryAmbient, o Nearby pode não conseguir ouvir áudio de dispositivos por perto. Se o app usar o AVAudioSessionCategoryRecord, o Nearby não poderá transmitir áudio para dispositivos por perto. O padrão é YES.
