iOS 根据经纬度翻译成详细位置的各种方法(2)

调用的话就是这样
 jsonString = [NSString stringWithFormat:SEARCH_GOOGLE,location.coordinate.latitude,location.coordinate.longitude,@"food"];
 jsonString = [NSString stringWithFormat:SEARCH_GOOGLE,location.coordinate.latitude,location.coordinate.longitude,@"bus_station"];
jsonString = [NSString stringWithFormat:SEARCH_GOOGLE,location.coordinate.latitude,location.coordinate.longitude,@"hospital"];

PS2：有个功能，如果长时间按住地图上某个地方，如何获取其经纬度，进而对其显示位置呢？

//开始点击长按，不然会执行2次。 
if (sender.state==UIGestureRecognizerStateBegan) { 
    //isLongPress=YES; 
    CGPoint touchPoint=[sender locationInView:self.myMapView]; 
    CLLocationCoordinate2D touchCoordinate=[self.myMapView convertPoint:touchPoint toCoordinateFromView:self.myMapView];//将触摸点转换经纬度 
    //反向解析长按时的大头针的信息 
    location =[[CLLocation alloc]initWithLatitude:touchCoordinate.latitude longitude:touchCoordinate.longitude];
