放大屏幕中心-Google Maps iOS SDK Swift [英] Zoom in the center of the screen - Google Maps iOS SDK Swift

问题描述

我目前正在迅速构建一个iOS应用.我在自己的一个ViewController中放置了一个GMSMapView，并在屏幕中间放置了一个标记.标记永远不会移动.

I am currently building an iOS app in swift. I put a GMSMapView inside one of my ViewControllers and I put a marker in the middle of the screen. The marker never moves.

当我缩放或缩放时，标记位置会改变，与标记关联的地址也会改变.我希望能够缩放与Uber应用上相同的精确位置.

When I zoom or unzoom, the marker position changes and so does the address associated to the marker. I want to be able to zoom on the same exact position as it is done on the Uber app.

我已经阅读了关于stackoverflow的一些答案，例如: Google Maps Center在缩放时，但没有一个起作用.

I've read some of the answers on stackoverflow like this one : Google Maps Center while zooming but none of them worked.

是否可以直接使用Google Maps SDK执行此操作，还是应该编写一种算法来保存最近的已知位置并放大该位置?

Is there a way to do this directly with the Google maps SDK or should I write an algorithm that saves the last known position and zooms on this position ?

推荐答案

如果我正确理解，您是否希望在屏幕中间居中，然后进行放大和缩小，但没有mapview滚动?

If I understand correctly, you are looking to centre in the middle of the screen, then zoom in and out, but not have the mapview scroll?

Google地图确实具有此功能.为了防止地图视图滚动，请为您的地图视图实现allowScrollGesturesDuringRotateOrZoom = false

Google maps does have this feature. To prevent the mapview from scrolling, implement allowScrollGesturesDuringRotateOrZoom = false for your mapview.settings:

myMapView.settings.allowScrollGesturesDuringRotateOrZoom = false
