I have tried following code in iPhone MapView

UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(checkpinch)]; [self.mapView addGestureRecognizer:pinch]; [pinch release];

Add following code in your view did load and add Gesture recognizer delegate in you .h file.

Enjoy...:)

[self.view insertSubview:mapView atIndex:0];

//Gesture reconizer
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(checkpinch)];
[pinch setDelegate:self];
[pinch setDelaysTouchesBegan:YES];
[self.mapView addGestureRecognizer:pinch];
[pinch release];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(checktap)];
[singleTap setDelegate:self];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired =2;
[self.mapView addGestureRecognizer:singleTap];
[singleTap release];


UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(checktap)];
[doubleTap setDelegate:self];
doubleTap.numberOfTapsRequired = 2;
doubleTap.numberOfTouchesRequired =1;
[self.mapView addGestureRecognizer:doubleTap];
[doubleTap release];
