添加长按手势，在地图上加注解标识

为mapView添加长按手势

UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizeralloc]initWithTarget:selfaction:@selector(pick:)];//添加手势

   [mapViewaddGestureRecognizer:longPress];

实现pick:方法

 

//长按手势处理方法

- (void)pick:(id)sender{

   CGPointpickPoint =[(UILongPressGestureRecognizer*)sender locationInView:mapView];//取到长按的点

   NSLog(@"%f,%f",pickPoint.x,pickPoint.y);

   // -(CLLocationCoordinate2D)convertPoint:(CGPoint)pointtoCoordinateFromView:(UIView *)view

   CLLocationCoordinate2Dcoornation = [mapViewconvertPoint:pickPoint toCoordinateFromView:mapView];//获取经纬度

    

   MyAnotation*ann =[[MyAnotation alloc]init];//初始化注解对象

   ann.coordinate =coornation;//定位经纬度

   [self.mapView addAnnotation:ann];//添加注解

    

}
