CGPoint touchPoint = [gestureRecognizer locationInView:self.mapView];
CLLocationCoordinate2D touchMapCoordinate =
[self.mapView convertPoint:touchPoint toCoordinateFromView:self.mapView];
//这里的touchMapCoordinate.latitude和touchMapCoordinate.longitude就是你要的经纬度，
NSLog(@"%f",touchMapCoordinate.latitude);
NSLog(@"%f",touchMapCoordinate.longitude);
//30.264998 120.122538 30.285012 120.117989
LocationObject *aLocationObject = [[LocationObject alloc]initWithTitle:@"hello" latitue:touchMapCoordinate.latitude longitude:touchMapCoordinate.longitude];
aLocationObject._subTitleString = @"world";
NSMutableArray *_mapAnnotations = [[NSMutableArray alloc]initWithCapacity:1];
[_mapAnnotations addObject:aLocationObject];
[self.mapView addAnnotations:_mapAnnotations ];
[_mapAnnotations release];
[aLocationObject release];

}
}

希望能帮到你，求采纳。
