我发现很难解决此错误,请谁能帮助我
Xcode 7 Beta 2

设置UITouch?没有名为Generator的成员

      override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
        for obj in touches {
            if let touch = obj as? UITouch {
                let view = self.touchToView[touch]

                self.handleControl(view, controlEvent: .TouchCancel)

                self.touchToView[touch] = nil
            }
        }

    }
}

最佳答案

您需要打开可选包装-试试

for obj in touches! {
   // code here
}
