我有 class Menu: SKScene，然后里面有一个 func touchesBegan，它给我以下错误:
Method 'touchesBegan(:withEvent:)' with Objective-C selector 'touchesBegan:withEvent:' conflicts with method 'touchesBegan(:withEvent:)' from superclass 'UIResponder' with the same Objective-C selector
无论如何，如果我在它说的函数前面添加覆盖:
Method does not override any method from its superclass.
有什么想法吗？完整代码:
import SpriteKit
class Menu: SKScene {
var title : SKLabelNode?
var start : SKLabelNode?
override func didMoveToView(view: SKView) {
backgroundColor = SKColor.whiteColor()
self.title = SKLabelNode(fontNamed: "Chalkduster")
self.start = SKLabelNode(fontNamed: "Chalkduster")
self.title!.name = "title"
self.start!.name = "new"
self.addChild(self.title!)
self.addChild(self.start!)
}
func touchesBegan(touches: NSSet, withEvent even: UIEvent) {
self.menuHelper(touches)
}
func menuHelper(touches: NSSet) {
for touch in touches {
let nodeAtTouch = self.nodeAtPoint(touch.locationInNode(self))
if nodeAtTouch.name == "title" {
print("Title pressed")
}
else if nodeAtTouch.name == "new" {
print("Start pressed")
}
}
}
