定位GMSMapView以一次显示多个注释 [英] Positioning GMSMapView to show multiple annotations at once

问题描述

我的问题与这个很相似，除了MKMapView。 a>
如何使用Google地图执行相同的过程（调整地图大小以适应屏幕上的所有注释/标记）？
据我所知，我必须将MKCoordinateRegion转换为GMSProjection，是我的方式吗？

My question is quite similar to this, except MKMapView. How can I do the same process(resize the map to fit all annotations/markers on screen at once) with Google Maps? As I understand I have to convert MKCoordinateRegion to GMSProjection, is my way right?

推荐答案

：

Thats very simple, just:

@property (nonatomic, strong) GMSMapView *mapView;

- (void)didTapFitBoundsWithMarkers:(NSArray *)markers
{
GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] init];;

for (GMSMarker *marker in markers) {
    bounds = [bounds includingCoordinate:marker.position];
}

GMSCameraUpdate *update = [GMSCameraUpdate fitBounds:bounds];
[self.mapView moveCamera:update];
[self.mapView animateToViewingAngle:50];
}
