Combine é uma
framework para lidar com eventos assíncronos combinando operadores de processamento de eventos.
A função Combine facilita a leitura e a manutenção do código, centralizando o código de processamento de eventos.
A biblioteca GoogleMapsPlatformCombine.
é uma biblioteca Swift que retorna
Publishers
para o SDK do Maps para iOS e o SDK do Places para iOS. Assim, você aproveita
do amplo conjunto de recursos de combinação.
Instalação
Consulte a
biblioteca GoogleMapsPlatformCombine.
no GitHub para conferir os requisitos mais recentes do sistema e instruções de instalação.
Exemplo de uso
A biblioteca GoogleMapsPlatformCombine inclui as
Classe GMSMapViewPublisher
que contém propriedades de editor que permitem que você se inscreva em eventos emitidos pelo mapa.
O exemplo a seguir configura uma instância GMSMapViewPublisher para assinatura
eventos de mudança de câmera:
let publisher = GMSMapViewPublisher(mapView: mapView)
publisher.didChangeCameraPosition.sink { cameraPosition in
print("Camera position at \(cameraPosition.target)")
}
