如何(谷歌地图iOS)获取当前地图视图绑定？

Question

如何(谷歌地图iOS)获取当前地图视图绑定？我发现ios api与谷歌地图javascript api完全不同.

Answer 1

做了一些研究后,下面是工作代码.

// work only on real device, not work on simulator



- (void)mapView:(GMSMapView *)mapView
idleAtCameraPosition:(GMSCameraPosition *)cameraPosition {




    // show current map view bound
    GMSVisibleRegion visibleRegion = [mapView_.projection visibleRegion];
    GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc]initWithRegion:visibleRegion];

    CLLocationCoordinate2D northEast = bounds.northEast;
    CLLocationCoordinate2D northWest = CLLocationCoordinate2DMake(bounds.northEast.latitude, bounds.southWest.longitude);
    CLLocationCoordinate2D southEast = CLLocationCoordinate2DMake(bounds.southWest.latitude, bounds.northEast.longitude);

    CLLocationCoordinate2D  southWest = bounds.southWest;


    NSLog(@"NORTH-EST: %.5f",northEast.latitude);
    NSLog(@"NORTH-EST: %.5f",northEast.longitude);

    NSLog(@"NORTH-WEST: %.5f",northWest.latitude);
    NSLog(@"NORTH-WEST: %.5f",northWest.longitude);

    NSLog(@"South-EST: %.5f",southEast.longitude);
    NSLog(@"South-EST: %.5f",southEast.latitude);

    NSLog(@"SOUTH-WEST: %.5f",southWest.latitude);
    NSLog(@"SOUTH-WEST: %.5f",southWest.longitude);


}
