如何在objective C中动态地在Google地图上创建多个图钉

#import <GoogleMaps/GoogleMaps.h>

// 在视图控制器中创建地图视图
GMSMapView *mapView = [[GMSMapView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:mapView];

// 创建图钉
GMSMarker *marker1 = [[GMSMarker alloc] init];
marker1.position = CLLocationCoordinate2DMake(37.7749, -122.4194); // 设置图钉位置
marker1.title = @"San Francisco"; // 设置图钉标题
marker1.icon = [UIImage imageNamed:@"pin_icon"]; // 设置图钉图标

// 将图钉添加到地图视图
marker1.map = mapView;

// 创建多个图钉
NSArray *locations = @[
    @{@"title": @"Location 1", @"latitude": @(37.7749), @"longitude": @(-122.4194)},
    @{@"title": @"Location 2", @"latitude": @(37.7833), @"longitude": @(-122.4167)},
    @{@"title": @"Location 3", @"latitude": @(37.7933), @"longitude": @(-122.4067)}
];

for (NSDictionary *location in locations) {
    GMSMarker *marker = [[GMSMarker alloc] init];
    marker.position = CLLocationCoordinate2DMake([location[@"latitude"] doubleValue], [location[@"longitude"] doubleValue]);
    marker.title = location[@"title"];
    marker.map = mapView;
}
