使用选择器'touchesBegan：withEvent：'的重写方法具有不兼容的类型'（NSSet，UIEvent）->（）'

Swift 1.2（Xpre 6.3）
引入了

Set

NSSet

该

UIResponder

func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent)

您可以像这样覆盖它：

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {    if let touch = touches.first as? UITouch {        // ...    }    super.touchesBegan(touches , withEvent:event)}

Swift 2（Xpre 7）更新：（ 比较Swift 2中的OverrideFunc错误]

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {    if let touch = touches.first {        // ...    }    super.touchesBegan(touches, withEvent:event)}

Swift 3更新：

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {    if let touch = touches.first {        // ...    }    super.touchesBegan(touches, with: event)}
