tvOS how to recognize remote gestures for Objective C?

Question

How would I go about recognizing remote swipes and button taps with Objective C for tvOS? Everywhere I find comes up with Swift, which I'm not used to yet.

Thanks!

Answer 1

The Swift code from your example:

let swipeDown:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedDown:"))
swipeDown.direction = .Down
view.addGestureRecognizer(swipeDown)

func swipedDown(sender:UISwipeGestureRecognizer){
    NSLog("It worked")
}

Swift 5:

let swipeDown:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedDown:"))
swipeDown.direction = .down
view.addGestureRecognizer(swipeDown)

func swipedDown(sender:UISwipeGestureRecognizer){
    NSLog("It worked")
}

Translating to Objective C:

- (void)viewDidLoad {
    [super viewDidLoad];

    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeDown:)];
    recognizer.direction = UISwipeGestureRecognizerDirectionDown;
    [self.view addGestureRecognizer:recognizer];
}

- (void)swipeDown:(UISwipeGestureRecognizer *)sender
{
    NSLog(@"It works");
}

Which seems to work:
