iOS 觸摸的位置放一個大頭針

UITapGestureRecognizer *mTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapPRess:)];  
    [self.mapView addGestureRecognizer:mTap];  

事件實現如下：
[cpp] view plaincopyprint?
- (void)tapPress:(UIGestureRecognizer*)gestureRecognizer {  
      
   

    CGPoint touchPoint = [gestureRecognizer locationInView:_mapView];//這里touchPoint是點擊的某點在地圖控件中的位置

    CLLocationCoordinate2D touchMapCoordinate =

    [_mapView convertPoint:touchPoint toCoordinateFromView:_mapView];//這里touchMapCoordinate就是該點的經緯度了

    NSLog(@"touching %f,%f",touchMapCoordinate.latitude,touchMapCoordinate.longitude);

        CLLocationCoordinate2D location=CLLocationCoordinate2DMake(touchMapCoordinate.latitude, touchMapCoordinate.longitude);

        KCAnnotation *annotation=[[KCAnnotation alloc]init];

        annotation.title=@"Kenshin&Kaoru";

        annotation.subtitle=@"Kenshin Cui's Home";

        annotation.coordinate=location;

        annotation.image=[UIImage imageNamed:@"icon_paopao_waterdrop_streetscape.png"];

        annotation.icon=[UIImage imageNamed:@"icon_mark2.png"];

        annotation.detail=@"Kenshin Cui...";

        annotation2.rate=[UIImage imageNamed:@"icon_Movie_Star_rating.png"];

        [_mapView addAnnotation:annotation2];

}
