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google map javascript api完全不同。

Answer 1

经过一番研究后，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);


}
