余分なコードが追加されました

私はxcodeが初めてです。マップ上にさまざまな色で注釈を作成することができました。私がやりたいのは、各注釈が開示ボタンで新しい場所につながるようにすることです。右矢印の開示ボタンを実装したので、知る必要があるのは、それをリンクして、各注釈が選択した別のビュー コントローラーにつながるようにする方法です。これが私の MapViewController 実装の現在のコードです。

これをチェックして：

-(void)clickOnMapAnnotation:(UIButton*)送信者

{

int AnnotationClicked =sender.tag;

if(AnnotationClicked ==1)
{
    //PushViewcontroller1
}
else
{
      //PushViewcontroller1
}

}

  • (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id ) 注釈 {

    if ([注釈 isKindOfClass:[MKUserLocation クラス]]) return nil;

    MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pin"];

    int annId = ((LocationAnnotation *)annotation).idNumber; annView.pinColor = (annId == 1) ? MKPinAnnotationColorPurple : (annId == 2) ? MKPinAnnotationColorGreen : MKPinAnnotationColorRed;

    //新しいView ControllerにつなげたいDetail Disclosureボタン。

    UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; [rightButton addTarget:self action:@selector(clickOnMapAnnotation:) forControlEvents:UIControlEventTouchUpInside]; rightButton.tag = annId;

    annView.rightCalloutAccessoryView = rightButton;

    annView.canShowCallout = はい;

    annView を返します。

}

rightbutton のタグを annID に設定します。

rightButton.tag = annId;

次に、Selector を touchup イベントに割り当てます: [rightButton addTarget:self action:@selector(YourMethod:) forControlEvents:UIControlEventTouchUpInside];

YourMethod では、senders タグを使用して別のビューに移動できます

-(void)YourMethod:(UIButton*)sender { if(sender.tag==1)

{

//viewcontroller1 をプッシュ

}

そうしないと

{

//ビューコントローラーをプッシュ

}

戻る; }
