I am stuggling to pass one of the iOS challenges please help

Assume we are creating an app to display random quotes. So far our app has a label and a button that have been added to the view. We need to create an 'IBAction' for our button. Please define a method called 'buttonPressed' and make sure it returns an 'IBAction'.

import "THViewController.h"

@implementation THViewController

  • (IBAction)buttonPressed;

@end

However, I am not getting it correct. Please help.

it looks like you are currently putting this code in the implementation file for this class. You need to put your method declaration in the interface file (.h) not the implementation (.m). There should be a tab where you can switch between files in the challenge engine. other than that your code looks correct

Like Stone said, usually methods are declared in the .h file. However if I remember on the code challenges you can't change between .h (interface) and .m (implementation) files. But when you define methods in the .m file the syntax is a little different. To declare in the .h file you use what you have i.e.

  -(IBAction) buttonPressed;

and then in the .m file you need {} on the end like so:

-(IBAction) buttonPressed{
   //stuff to do when our button is pressed
}

Without seeing the question I can't tell for sure but hopefully this helps.
