Question

I have a UIAlertView with buttons and I am trying to make these buttons execute an action. The problem is I have an “undeclared identifier” in my method.

THE ISSUE I SEE http://tinypic.com/view.php?pic=28qvhom&s=6

THE CODE

The alert view

 UIAlertView *alert = [[UIAlertView alloc]
    initWithTitle:@"Well done!"
    message: @"You got all 20 in Time: x"
    delegate:nil
    cancelButtonTitle:nil
    otherButtonTitles:@"Save and Quit", @"Quit", nil];


[alert show];}

the void

-(void)alertView:(UIAlertView* )alertView 
clickedButtonAtIndex:(NSInteger)buttonIndex         

{

    if(buttonIndex==0) {/*some action */ }
    else if(butonIndex==1){/*some action */}

}


     //I aso have <UIAlertViewDelegate> in my .h file.   

Answer 1

The problem is in else if(butonIndex==1) you’re missing the second “t” in the word button.

For future reference, Xcode’s “Fix-It” feature will fix trivial mistakes like this for you.

Click the red circle to activate the fix-it menu then simply hit enter.

EDIT:

Do this:

- (void)myMethod{

}

-(void)alertView:(UIAlertView* )alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{

}

Not this:

- (void)someMethod
{
    -(void)alertView:(UIAlertView* )alertView clickedButtonAtIndex:(NSInteger)buttonIndex
    {

    }
}

If this isn’t the case, then you are missing a closing brace “}” at the end of the method before the alert view delegate.
