Need help calling a method after pressing a button from a UIActionSheet

I have a UIActionSheet that I am able to successfully call from a UIBarButtonItem in my app. However, when I click on a button that is on the UIActionSheet, the method that I am trying to get it to call does not appear to be called, and the UIActionSheet goes away. My relevant code looks like this:

In my MapViewController.h file:

@interface MapViewController : UIViewController<MKMapViewDelegate, UIActionSheetDelegate>{

In my MapViewController.m file:

-(IBAction)showActionSheet {
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Share your favourite restaurant with your friends" delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"EMail",@"Facebook",@"Twitter",nil];
[actionSheet showInView:self.view];
[actionSheet release];
}

-(void)actionS开发者_Go百科heet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if(buttonIndex == 0)
    NSLog(@"You chose email!");
if(buttonIndex == 1)
    NSLog(@"You chose facebook!");
if(buttonIndex == 2)
    NSLog(@"You chose twitter!");
}

Can anyone see where I am going wrong? My personal hunch is that it may have something to do with how I am implementing the UIActionSheetDelegate interface.

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Share your favourite restaurant with your friends" delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"EMail",@"Facebook",@"Twitter",nil];

should be

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Share your favourite restaurant with your friends" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"EMail",@"Facebook",@"Twitter",nil];

And also make sure your .h file implements the UIActionSheetDelegate protocol

You are passing nil as the delegate, but the delegate is your view controller, so pass self:

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Share your favourite restaurant with your friends" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"EMail",@"Facebook",@"Twitter",nil];

May be you forget to set the delegate , Add below in your code

actionSheet.delegate = self ;

From the Documentation ... The receiver’s delegate or nil if it doesn’t have a delegate.

@property(nonatomic, assign) id<UIActionSheetDelegate> delegate
