Answer 1

let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipes(sender:))) 

@objc func handleSwipes(sender: UISwipeGestureRecognizer) { 
    // ... 
} 

무엇입니까 오류 내 프로그램

override func viewDidLoad() { 
    super.viewDidLoad() 

    let leftSwipe = UISwipeGestureRecognizer(target: self, action: Selector(("handleSwipes:"))) 
    let rightSwipe = UISwipeGestureRecognizer(target: self, action: Selector(("handleSwipes:"))) 

    leftSwipe.direction = .left 
    rightSwipe.direction = .right 

    self.view.addGestureRecognizer(leftSwipe) 
    self.view.addGestureRecognizer(rightSwipe) 
} 

func handleSwipes(sender: UISwipeGestureRecognizer) { 
    if (sender.direction == .left) { 
     headerLabel.text = "Zodiac Yearly" 
    } 

    if (sender.direction == .right) { 
     headerLabel.text = "Characteristics" 
    } 
}
