MKMapView 响应touchesbegan事件

我写个iphone程序，想实现单击MKMapView弹出另一个视图，不用手势识别，怎么捕获MKMapView的touchesBegan事件。我是在UIview上添加了一个MKMapView，运行程序，单击MKMapView的时候，touchesBegan没有被调用啊，改怎么解决呢

[解决办法]

C/C++ code

   // 1、在viewDidLoad中添加我们要捕获的手势：        UITapGestureRecognizer *mTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapPress:)];    [_mapView addGestureRecognizer:mTap];    [mTap release];- (void)tapPress:(UIGestureRecognizer*)gestureRecognizer {       //用做啥自己写在这里}
