如何（谷歌地圖iOS）獲取當前地圖視圖綁定？

Question

如何（谷歌地圖iOS）獲取當前地圖視圖綁定？ 我發現ios api與google map javascript api完全不同。

Answer 1

做了一番研究後，下面是工作代碼。

// 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); 


}
