Obj-C - Google Maps SDK获取所选标记的数据？

#import <GoogleMaps/GoogleMaps.h>

@interface ViewController : UIViewController <GMSMapViewDelegate>

@property (nonatomic, strong) GMSMapView *mapView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // 创建地图视图
    self.mapView = [[GMSMapView alloc] initWithFrame:self.view.bounds];
    self.mapView.delegate = self;
    [self.view addSubview:self.mapView];
    
    // 创建标记
    GMSMarker *marker = [[GMSMarker alloc] init];
    marker.position = CLLocationCoordinate2DMake(37.7749, -122.4194);
    marker.title = @"San Francisco";
    marker.map = self.mapView;
}

- (void)mapView:(GMSMapView *)mapView didTapMarker:(GMSMarker *)marker {
    // 获取所选标记的数据
    NSString *title = marker.title;
    CLLocationCoordinate2D position = marker.position;
    
    // 在控制台打印标记的数据
    NSLog(@"Selected Marker - Title: %@, Position: (%f, %f)", title, position.latitude, position.longitude);
}
