Question

我正在开发一个简单的地图，我想在地图上找到一家公司，例如公司名称。例如，“Apple Inc。”。

你知道我该怎么办？

非常感谢！

您需要有一个实现MKAnnotation协议的类。这是一个例子

@interface MapPin : NSObject<MKAnnotation> {
    CLLocationCoordinate2D coordinate;
    NSString *title;
    NSString *subtitle;
}

@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
@property (nonatomic, readonly) NSString *title;
@property (nonatomic, readonly) NSString *subtitle;

- (id)initWithCoordinates:(CLLocationCoordinate2D)location placeName:(NSString *)placeName description:(NSString *)description;

@end

以下是实施：

@implementation MapPin

@synthesize coordinate;
@synthesize title;
@synthesize subtitle;

- (id)initWithCoordinates:(CLLocationCoordinate2D)location placeName:placeName description:description {
    self = [super init];
    if (self != nil) {
        coordinate = location;
        title = placeName;
        [title retain];
        subtitle = description;
        [subtitle retain];
    }
    return self;
}

- (void)dealloc {
    [title release];
    [subtitle release];
    [super dealloc];
}


@end

然后，在MapView中，您需要添加公司位置，如下所示。

CLLocationCoordinate2D coord = [[[CLLocation alloc] initWithLatitude:35.936902 longitude:-79.024953] coordinate];//Here you need to mention your company latitude and longitude
MapPin *pin = [[MapPin alloc] initWithCoordinates:coord placeName:@"Apple Inc" description:@""];
[map addAnnotation:pin];

希望这会有所帮助....
