GMSCollisionBehaviorRequired (padrão): sempre mostrar o marcador, independentemente do conflito. Esse é o comportamento padrão. Não tem impacto na exibição de outros marcadores ou rótulos de mapa de base.
GMSCollisionBehaviorOptionalAndHidesLowerPriority: só mostrar o marcador se ele não se sobrepuser a outros elementos. Em caso de conflito, o marcador com o maior zIndex vai aparecer. Se eles tiverem o mesmo
zIndex, aquele com a posição vertical mais abaixo na tela será mostrado.
GMSCollisionBehaviorRequiredAndHidesOptional: sempre mostrar o marcador, independentemente do conflito, e ocultar todos os GMSCollisionBehaviorOptionalAndHidesLowerPriority. Só mostrar o marcador se ele não se sobrepuser a outros elementos. Não
GMSCollisionBehaviorRequired. Em caso de conflito, o marcador com o maior zIndex vai aparecer. As regras de colisão para marcadores com o mesmo zIndex são indefinidas.
Swift
// Defines a marker to always display and hide any marker or label overlay with this marker in the base mapmarker.collisionBehavior=.requiredAndHidesOptional
Objective-C
// Defines a marker to always display and hide any marker or label overlay with this marker in the base mapmarker.collisionBehavior=GMSCollisionBehaviorRequiredAndHidesOptional
