나는 생각할 수있는 모든 순열을 시도해보고 Swift에 관한 모든 종류의 문서를 읽었지만 어디에도 없습니다. 여기 코드는 다음과 같습니다간단한 Swift #selector를 컴파일 할 수 없습니다.
class AFSelectionState: GKComponent {
let clearSelectionIndicator: (Set<Int>?) -> Void
let setSelectionIndicator: (Set<Int>) -> Void
init(setSelectionIndicator: @escaping (Set<Int>) -> Void, clearSelectionIndicator: @escaping (Set<Int>?) -> Void) {
self.clearSelectionIndicator = clearSelectionIndicator
self.setSelectionIndicator = setSelectionIndicator
}
}
class GameScene: SKScene, SKViewDelegate {
var selectionState: AFSelectionState!
override func sceneDidLoad() {
...
/****************** Compiler errors coming up ****************
**
** Tried #selector(setSelectionIndicator_(_:))
** Got "Cannot convert value of type 'Selector' to expected
** argument type '(Set<Int>) -> Void'"
** From what I've read, the above should be working, but you know
** how it is when people say "should".
**
** Tried #selector(setSelectionIndicator_(_:) ->())
** Got "Expected type before '->'".
**
** Tried all sorts of other stuff. There's something about
** selectors that I'm missing.

*********************** Et cetera! *************************/
selectionState = AFSelectionState(
setSelectionIndicator: #selector(setSelectionIndicator_(_:)),
clearSelectionIndicator: #selector(clearSelectionIndicator_(_:))
)
...
}
}
