私は Xcode を初めて使用し、基本的には、MKMapView各ピンに個別の色を追加したいと考えています。現在、ピンに注釈を付けています。
LocationAnnotation.h:
@interface LocationAnnotation : NSObject <MKAnnotation>
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *subtitle;
@end
LocationAnnotation.m:
#import "LocationAnnotation.h"
@implementation LocationAnnotation
@synthesize coordinate, title, subtitle;
@end
私の各座標は、MainMapViewController.h で次のようになります。
#define TheKingBill_LATITUDE 50.431379
#define TheKingBill_LONGITUDE -3.685495
//Annotation
NSMutableArray * locations = [[NSMutableArray alloc] init];
CLLocationCoordinate2D location;
LocationAnnotation * myAnn;
//The King Bill Annotation
myAnn = [[LocationAnnotation alloc] init];
location.latitude = TheKingBill_LATITUDE;
location.longitude = TheKingBill_LONGITUDE;
myAnn.coordinate = location;
myAnn.title = @"The King Bill";
myAnn.subtitle = @"Another Pub In Town";
[locations addObject:myAnn];
//The Seven Stars Annotations
myAnn = [[LocationAnnotation alloc] init];
location.latitude = TheSevenStars_LATITUDE;
location.longitude = TheSevenStars_LONGITUDE;
myAnn.coordinate = location;
myAnn.title = @"The Royal Seven Stars Hotel";
myAnn.subtitle = @"Hotel In Town";
[locations addObject:myAnn];
[self.MainMapView addAnnotations:locations];
各ピンの色を変えるために何を追加する必要があるかについてのアイデアはありますか?
ありがとう！
さて、この LocationAnnotation ファイルにリンクする他のマップに問題があります。これにもカラーピンを追加したいです。新しいコードが以前の mapviewcontroller と同じであれば理想的です。これがコードです...
