Passing the value of a textfield to a function on CocoaTouch

I have the following code on the .h file:

@interface ComposeViewController : UIViewController {
    id  delegate;
    IBOutlet UITextField *notificationTitle;
}
@property (nonatomic, assign) id  delegate;
- (IBAction)done:(id)sender;
- (void)scheduleAlert;
@end

And on the .m file

- (void)scheduleAlert {
        // open an alert with just an OK button
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" message:(@"Hi") delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];

      开发者_开发技巧  [alert release];
}

I want to put the content of the NSString *notificationTitle on the message propietry of the *alert. If I pass using that code it crashes

- (void)scheduleAlert {
        // open an alert with just an OK button
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" message:(@"%@", notificationTitle)
                               delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        [alert release];
}

How I may pass the *notificationTitle to *alert message?

Thank you in advance :)

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" 
                          message:notificationTitle
                          delegate:self 
                          cancelButtonTitle:@"OK" 
                          otherButtonTitles: nil];

or

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" 
                          message:[NSString stringWithFormat:@"This is the string: %@", notificationTitle]
                          delegate:self 
                          cancelButtonTitle:@"OK" 
                          otherButtonTitles: nil];

for UIText field, you should use its text property like this

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView" message:notificationTitle.text delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
