マップビューにポイントをプロットしようとしています。2つのファイルを作成しました。1。nsobjectを拡張するファイル、および2.ビューを拡張するファイル。両方のファイルのソースコードは次のとおりです。
#import "gpMapViewAnnotations.h"
@implementation gpMapViewAnnotations
@synthesize title, coordinate;
- (id)initWithTitle:(NSString *)ttl andCoordinate:(CLLocationCoordinate2D)c2d {
title = ttl;
coordinate = c2d;
return self;
}
これはインターフェースファイルのコードです。
#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
@interface gpMapViewAnnotations : NSObject <MKAnnotation>{
NSString *title;
CLLocationCoordinate2D coordinate;
}
@property (nonatomic, copy) NSString *title;
@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
- (id)initWithTitle:(NSString *)ttl andCoordinate:(CLLocationCoordinate2D)c2d;
@end
@終わり
これがビューファイルのソースコードです。
#import <UIKit/UIKit.h>
#import <MapKit/Mapkit.h>
#import "ASIHTTPRequestDelegate.h"
#import "AppDelegate.h"
#import "gpMapViewAnnotations.h"
@interface gpViewController : UIViewController
< ASIHTTPRequestDelegate, MKMapViewDelegate>
{
MKMapView *gpMapView;
gpMapViewAnnotations *gpAnnotations;
}
@property (strong, nonatomic) IBOutlet MKMapView *gpMapView;
@end
そして、ここに実装ファイルがあります：
#import "gpViewController.h"
#import "ASIHTTPRequest.h"
#import "Parser.h"
#import "AppDelegate.h"
#import "TFHpple.h"
#import "TouchXML.h"

単純な点をプロットする際にどこが間違っているのか、私には手がかりがありません。xmlファイルを読み取って作成した配列を使用して複数のポイントを配置する必要があります。しかし、単純な点でさえ、現在はプロットされていません。ここで私が間違っていることはありますか？
