Code Challenge: Adding Login and Sign Up Screens

Hi, I could really use some help with this one.

In the view controller below about songs, tapping on a button to add a new song needs to perform a segue to another view controller. The button is wired up to an IBAction with the signature '- (void)addSong'. Start by defining this method.

#import "MusicViewController.h"

@implementation MusicViewController

- (void)viewDidLoad {
    [super viewDidLoad];

- (IBAction)addSong:(id)sender {
}
}

@end

That's all I got.

The method signature is provided in the question. So you should define it exactly as mentioned: - (void)addSong.

Hi Amit,

Thanks for replying. I'm still having difficultly with this one.

import "MusicViewController.h"

@implementation MusicViewController Hey Amit, thanks for the reply. I'm still struggling with this. I know I need to tell it to perform a segue right?

  • (void)viewDidLoad { [super viewDidLoad];

  • (void)addSong:(id)sender { } }

@end

You cannot define one method inside another. The addSong is a separate method definition which means it's outside the curly braces of the viewDidLoad method. Also the method definition does not take an argument sender. It is simply-(void)addSong`.
