ios - 如何仅在 gmscircle 区域显示标记，否则在 ios 中隐藏

Question

如何仅在 GMSCirle 区域显示标记，否则隐藏在 iOS 中，我使用谷歌地图创建了 GMSCirle，现在我只想在 区域显示标记>GMSCirle 否则隐藏标记。

这是我的代码:

GMSMarker *centerPoint=[GMSMarker markerWithPosition:CLLocationCoordinate2DMake(16.301687, 80.419235)];
    centerPoint.icon=[UIImage imageNamed:@"PinImage.png"];

    circ.fillColor = [UIColor colorWithRed:0.25 green:0 blue:0 alpha:0.05];
    circ.strokeColor = [UIColor blackColor];
    circ.strokeWidth = 5;
    circ.tappable=true;
    circ.map = mapView_;
    mapView_.settings.myLocationButton=YES;
    mapView_.settings.zoomGestures=YES;
    mapView_.settings.zoomGestures=YES;
    mapView_.settings.compassButton=YES;
    mapView_.settings.rotateGestures=YES;
    mapView_.settings.scrollGestures=YES;
    mapView_.settings.tiltGestures=YES;
    mapView_.myLocationEnabled=YES;

如果有任何想法值得赞赏，我会努力奋斗，在此先感谢。

只是我只想知道如何在 iOS 中仅在特定区域显示标记

您可以使用以下简单的想法。

-(BOOL) checkMarker:(CLLocation*)locB

{
CLLocation *locA = [[CLLocation alloc]
                    initWithLatitude:24.590095
                    longitude:73.698256];

CLLocationDistance distance = [locA distanceFromLocation:locB];
NSLog(@"%f",distance);

if(distance <= RADIUS)
{
    NSLog(@"You are in Circle ");
    return true;
}
else
{
    NSLog(@"You are not in circle");
    return false;
    }
}
