iOS button dial

[mekopolis]

what i am attempting to do is when a user touches a butotn, it dials a number

i was going to use the open url through safari approach to dial out

and this code:

- (void)applicationDidFinishLaunching:(UIApplication *)application {	
	// Override point for customization after app launch
    
    // Schedule -showUsageAlertDialog on the next cycle of the event loop to give the 
    // application:handleOpenURL: delegate method an opportunity to handle an incoming URL.
    // If that delegate method is called, it sets the showUsageAlert to NO, which prevents
    // the usage dialog from being shown.
    showUsageAlert = YES;
    [self performSelector:@selector(showUsageAlertDialog) withObject:nil afterDelay:0.0];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{   
    showUsageAlert = NO;
	
    // You should be extremely careful when handling URL requests.
    // You must take steps to validate the URL before handling it.
    
    if (!url) {
        // The URL is nil. There's nothing more to do.
        return NO;
    }
    
    NSString *URLString = [url absoluteString];
    
    NSString *message = [NSString stringWithFormat:@"The application received a request to open this URL: %@. Be careful when servicing handleOpenURL requests!", URLString];
    
    UIAlertView *openURLAlert = [[UIAlertView alloc] initWithTitle:@"handleOpenURL:" message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [openURLAlert show];
    [openURLAlert release];
    
    if (!URLString) {
        // The URL's absoluteString is nil. There's nothing more to do.
        return NO;
    }
    
    // Your application is defining the new URL type, so you should know the maximum character
    // count of the URL. Anything longer than what you expect is likely to be dangerous.
    NSInteger maximumExpectedLength = 50;
    
    if ([URLString length] > maximumExpectedLength) {
        // The URL is longer than we expect. Stop servicing it.
        return NO;
    }
	
    return YES;
}

- (void)showUsageAlertDialog
{
    if (showUsageAlert) {
        NSString *message = @"To demonstrate how this application handles a URL request for the new URL type that it registers, enter a URL in Safari that begins the with scheme of the URL type (launchme://) and press the Go button.";
        self.usageAlertView = [[UIAlertView alloc] initWithTitle:@"Usage" message:message delegate:self cancelButtonTitle:@"Launch Safari" otherButtonTitles:nil];
        [self.usageAlertView show];
    }
}

- (void)dismissUsageAlert
{
    [self.usageAlertView dismissWithClickedButtonIndex:-1 animated:YES];
}

- (void)modalViewCancel:(UIAlertView *)alertView
{
    [alertView release];
}

- (void)modalView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if (buttonIndex != -1) {
        // Open Safari only if the user clicked the 'Launch Safari' button, but not if this
        // delegate method is called by UIKit to cancel it. In that case, buttonIndex is -1.
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.apple.com"]];
    }
    [alertView release];
}

- (void)dealloc {
	[window release];
	[super dealloc];
}

so do i do something like IBaction ...i think thats the wrong syntax
but do i use the button press syntax code, to execute the code above?

- (IBAction)dialnum {  code here } end
