如何在地圖上定位公司（mapkit iOS）

Question

我正在開發一個簡單的地圖，我想使用公司名稱在地圖上找到公司。例如「Apple Inc.」。

你知道我該怎麼做？

非常感謝！

你需要有實現MKAnnotation協議的類。下面是一個例子

@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 

下面是執行：

@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 

然後，在你的MapView你需要添加公司所在地像下面。

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]; 

希望這將有助於....
