Swift에서 여러 UIButtons의 탭 처리 방법

Question

레이블 텍스트로 한 자리 숫자의 레이블이있는 Swift에서 응용 프로그램을 만들려고합니다. 나는 라벨을 탭하고 정수를 증가시키고 싶다. 나는 Tic Tac Toe 앱에 대한 튜토리얼을 통해 각 라벨을 클리어 버튼 (1-36)으로 오버레이하고 탭을 사용하여 라벨을 증가시킬 수 있다고 배웠다. (1 -36) 텍스트 번호. 여태까지는 그런대로 잘됐다. 이 자습서에서는 switch 문을 사용하여 단추의 태그를 두드려서 사례를 Label 참조에 하드 코딩합니다. Tic Tac Toe는 3x3 그리드이기 때문에 괜찮습니다. 그리드는 6x6이고 36 개 모든 경우를 하드 코드하기에는 너무 게을러서입니다. 버튼 태그를 전달하고이 작업을 수행하는 더 똑똑한 방법이 있습니까?

나는 단추 레이블 텍스트 정수를 배열에 저장하고 거기에서 레이블을 업데이트하고/쓰기/쓰기를 생각하고 있습니다. 이것은 아마도 지금 가지고있는 것보다 낫지 만 스위치 문 문제를 해결할 것이라고는 생각하지 않습니다.

모든 조언을 주시면 감사하겠습니다.

추가 레이블 대신 단추의 label 속성을 사용하십시오. 이 모양은 다음과 같습니다.

@IBOutlet var Button1: UIButton! //Row one 
@IBOutlet var Button2: UIButton! 
@IBOutlet var Button3: UIButton! 
@IBOutlet var Button4: UIButton! 
@IBOutlet var Button5: UIButton! 
@IBOutlet var Button6: UIButton! 
.... 

@IBAction func increaseLabel(sender: UIButton) { 
    var currentLabel = sender.titleLabel.text.toInt()! 
    currentLabel = currentLabel + 1 
    sender.setTitle("\(currentLabel)", forState: .Normal) 
} 

그런 다음 모든 단추를 Interface Builder에서 해당 작업에 연결하십시오.
