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]; [self addSong]; // I add this line to add a song
}
@end
I can not recognize two things 1)The button is wired up to an IBAction with the signature '- (void)addSong'. 2)Start by defining this method.
How should I go to think of them

it means that he connected a Button (when touched) to the code using assistant editor (tuxedo guy) and name it "addSong"
2)Start by defining this method
it means you should put the method "- (void)addSong" in the implementation file

4,260 PointsThe methods in .h file must be exactly as the methods on the .m file
So all you have to do is copy the method to the implantation file
Write -(void)addSong{}
