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GMSCirle
区域显示标记,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;
如果有任何想法可以理解,我会挣扎很多,提前谢谢。

你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;
}
}
