Question

so i am using presentmodalviewcontroller to change the active views in an ipad app. however when i try to change it using the statement [self presentModalViewController:createCharacter animated:NO]; in an ibaction that is triggered by a button. however i get an error saying expected expression before ‘createCharacter’. createCharacter is a custom view controller that i have created… does anyone know what i am doing wrong? if you need any more relevant code just let me know,thanks

additional relevant code:

#import "createCharacter.h";


-(IBAction) buildCharacter{
    [self presentModalViewController:createCharacter animated:NO];      
}

createCharacter.h :

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface createCharacter : UIViewController {
    IBOutlet UIView *view;
}

@end

I’d love to see some code to look at, and without it maybe this advice will be wrong, BUT…in my experience I’ve always used IBActions with a single argument, and that argument has always been the sender, so something like tying a button press to `

-(IBAction) presentNewController:(id)sender` 

where sender is the button that was pressed.

If you use a method like that to detect the button press from IB, then in code what you would want is something like:

// In your current view controller, the target where you wired up the button
-(IBAction) presentNewController:(id)sender
{
    if([sender isEqual:<whatever button you expect>])
    {
        CustomController *con = [[[CustomController alloc] init] autorelease];
        [selfpresentModalViewController:con animated:YES];
    }
}
